BOILER

INTRODUCTION:-

M/S BHEL ,hardware ,manufacture the boiler installed in SSTPS .Each of the boiler are single drum ,tangential fired water tube naturally circulated over hanged ,balance draft, dry bottom reheat type and is designed for pulverizing coal firing with a maximum continuous steam output of 375t/h at 138 kg/cm2 pressure 540 degree cent.temp.

The thermal efficiency of each boiler at MCR is 86.8%.Four no. of bowl mills have been installed for each boiler .oil burner are provided for initially start up and stabilization of loaw load ESP (one for each boiler ) is arranged to handle flue gases from the resp. boiler s. The gases from ESP are discharge through 180mt height of chimney .ID fan and a motor are provided near the chimney to induce the flue gases.

The boiler is provided with a balance draft consisting of two forced draft(F.D.)fans and two induced draft fan . Flue gases are utilized to heat to secondary air for combustion in the tubular type air heaters installed in the boiler. Since the boiler furnace is maintained at a negative pressure so to avoid atm.air entering a furnace a hydraulic pressure is maintend at the furnace bottom .

The water filled in the stainless steel seal through the hydraulic seal between the furnace ash hopper and the water wall ring heater. Adequate clearance is also provided for the downward expansion of the furnace.

Ash is formed by the result of burning of coalinside furnace. A small quantity of ash is collected in the ESP and magnetic separator hopper. This collected ash is disposed off in a slurry form in the disposal area.

BASIC THEORY AND AUXILARIES

The boiler also termed, as steam generator is a container in which water can be feed and by the application of heat evaporated continuously in steam .The heat source is obtained by burning the fuel, which is coal hear in our case .

The walls contained in the boiler drum in the flow through the down corner water walls and then through risers back to the drum .This closed circuit movement of boiler water is termed as circulation . The water wall and water in this circuit absorb the heat energy applied in the furnace & gate heated up.

This give rises to the formation to steam in the water walls. The water mixture of water and steam continuously and move to the steam drum to its lightness .The mixture of water and steam contniously displaced the colder water in the drum there by establishing a natural circulation.

The separation of water particles and stem take place in the steam separator sand the saturated steam is led into the upper heater for further heating and water particle fall back in to the drum

SUPER HEATER:-

Super heater is meant to raise the temp. of steam i.e. the saturation temp .by absorbing heat from flue gases .Limiting value of boiler is 540 degree celcious. Super heater eliminate the formulation pf condensate during transporting of steam in pipe line and inside the early stage of turbine, which is harmful to the turbine blade and pipe lines .

Super heater section is composed of four section viz. plates, pendant, rear, horizontals and steam cooled walls. The plate section is located just above the furnace in front of the furnace arc. The pladent section is located in the back of screen walls tubes. The rear horizontal is located in the furnace rear gas pass above the economizer and the steam cooled wall section comprises of side ,front rear, and roof of the vertical real gas pass.

Desuperheater are provided in between the finiak super heater and preheater to control the super heated steam temp: feed water is used as a spray to control the temp. Super heated to steam is lead into the H.P. turbine through main stram stop valve and hydraulically operated high pressure quick closing stop valve (HPQCSV)governing valve .After doing the useful work in the HP turbine the steam is returned to reheater through the cold reheat line.

12

REHEATER:-

Reheater are used to raise the temp of steam from which point of the energy had been exerted in HP turbine with increasing no. of reheating stages. Reheating is continued till temp of steam reaches to 540d/c. Reheating require additional equipment like as:-

(a) Heating surface.(b) Boiler turbine connecting pipe and safety equipment like safety valve,

non return valve (NRV) .isolating valve, steam temp, regulating equipment etc.

A reheater is composed of two section viz. front pendent vertical spaced, rear pendent vertical spaced. The front pendent vertical section is located between the rear water wall hanger tube and the super heater plate section.

The rear pendent vertical spaced section is locatd above the furnace arc between the water cooled system wall tube and heat wall hanger tubes.

ECONOMIZER:-

The function of economizer in a steam generating unit is to absorb heat from the flue gases and added this as sensible heat to feed water before the water enter the evorpating ckt: of the boiler .

The coal of economizer are designed for horizontal placement which facilities the draining of the coal and the favor the arrangement in second path of boiler.

Water flow from bottom to the top so that steam in any form during the heat transfer can move along with water and prevent the block up steam, which will cause overheating and failure of economizer.

13

AIRPREHEATER:-

Air preheater is a heat exchanger in which air temp. is raised by transferring heat from other fluid such as flue gases. Since air heater can be successfully employed to reclaim heat from flue gas at lower temp. Level so that it is possible so that the heat ejected to chimney can be reduce to a great extent thus increasing the efficiency of boilers.

14

TURBINE

INTRODUCTION:-

M/S BHEL Hardware has manufactured the steam turbine and their auxiliaries installed .The turbine are three cylinder, compound 3000 rpm, double flow exhaust type reheat unit with initial parameter of 13 kg/cm2 and 5 low pressure heart are feed .the high pressure cylinder comprise of two curt is wheel as a regulation stage .Intermediate pressure cylinder comprise of twelve stage and each of the double flow section of the LP cylinder consist of four stage.

OPERATION:-

There are two lime steam line connecting the boiler to the turbine. The super heated steam enter the HP turbine and strike its blades hence it energy of steam is converted in to mechanical energy .the steam from HP turbine is reheated in reheater (boiler) and reheated steam is sent to IP turbine through hot steam line (HRH). Here second stage of energy conversion is take place .Then steam is sent to L P turbine from where it is ejected by vacuum ejector and condensed.

Here are two cold reheat and two hot reheat line connecting the reheater and turbine.In each of two live steam line one electrically operating isolating valve ,one water

separator and one quick closing stop valve are mounted .The direction of revolution of turbine is clock wise when looking at turbine from front bearing pedestal. For the oil lubrication of bearing and fore governing .The main oil pump driven shaft is assembled in to the front bearing pedestal of turbine itself.

E S P

E.S.P.THEORY:-

The full form of ESP is electro static preceptor .ESP is highly efficient device for extraction of suspended particle and fly ash from the industrial flue gases .

WORKING PRINCIPLE: -

ESP can handle large volume of gases from which solid particles are to be removed .

Advantage of ESP are :

(a) High ash collection efficiency.

(b) Low resistance path for gas flow.

An ESP can be defined as a device that utilized electric forces to separate suspended particle from flue gases.

WORKING STEPS:-

ESP consist of two sets of electrode , one in the form of thin wire, called discharge or emitting electrode in the form of plates. the emitting electrode are placed in the center or mid way between two plates and are two connected to –ve (negative) polarity of high voltage DC source of order of 37 kv while collecting electrode are connecting to +ve (positive) polarity.

The voltage gradient between electrode creates “CORONA DISCHARGE“ i.e. ionizing the gas molecules .The dust particle present in the flue gases accure negative charge and get deposit on collecting electrode . The deposited particle are removed by knocking the electrode by a process a called “ RAPPING” done by “ RAPPING MOTORS “ .

20

ASH HENDLING PLANT

INTRODUCTION:-

The ash handling system provide continuous collection of bottom ash from the furnace hearth and its intermediate removal by hydro ejectors to a common slurry sump. It also provide for removal of fly ash to the common slurry sump.

Each boiler is provided with ash precipitator for collecting the fly ash from the flue gases with high efficiency .to minimize the dust mains and to reduce the water of ID (induced draft ) fan .the fly ash separated from where it is mixed with water to form slurry and disposed off to pumping area by mean of hydro ash pumps .

Bottom ash from the boiler furnace is passed through slag crusher s and then slurred to the slurry chamber to the suction of the disposal pumps. These are high pressure and low pressure pump for this purpose. At at time one pump is working and other then are standby .From the ash disposal pump house ash slurry is pumped through pipeline to the ash dump area within about 1.5 km away from the ash disposal pump house .

To separate ash , discharge line are provided one for each unit but only one line is used .The ash slurry from the two units is taken in one discharge line through electrically operated valve.

CONTROL AND INSTRUMENTION CIRCLE

INTRODUCTION:-

Control and instrumental play a major role in realizing the following objective of any power plant.

(a) Safety for plant and personnel.(b) Longer eqipment life

Since a lot of process are involved and distribute are frequent , the correction can be carried out efficiency and quickly only by the introduction of atomic control system eliminating any possible human error .

A power system is a combination of many individual eqipment and system and for better performance of these individual equipments. the equipment are interdependent and interrelated with each other . Electrical interlock system connect these individual eqipment and operate s with required sequence. For example boiler is a system comprising milling plant ,ID fan, FD fans PA fans etc.

These equipment are interlocked in such a way that they are started /shut down in specific sequence in order to avoid damage to equipment and men .

Also equipment are so interlocked that in case of failure of running equipment to discharge its function , the reserve one is automatically put into service .

A system of automatic sequence control simplifier the operator duty.

SSTPS have divided three sections in instrumental and control circle: -

1. SWAS package 2. FSSS package3. ATRS package

SODIMAT

The measurement of sodium in industrial ultra pure waters s essential . The measurement is based on a direct potentiometric technique, which uses highly sensitive sodium glass electrode. The difference of potential between the glass electrode and the reference electrode is directly proportional to the sodium concentration.

Modern high-pressure power plants require feed water of very high purity. Safety in that sector is of great importance and the sodium measurement plays a specific role compared to pH, conductivity and silica trace.

Actually sodium cations and anions are always linked. Most cations have a corrosive influence in water and vapour cooling circuits. Became of this chemical link between sodium cations and anions, sodium measurement presents particularly important risk of corrosion and other effects. The SODIMAT uses a sodium sensitive glass electrode to measure sodium in a sample which has been previously conditioned to a Ph>10.

HYDRASTAT

Low-carbon steel exhibits a significantly improved resistance to corrosion it in contact with water of high alkalinity (pH 9-10).

High pressure circuits operating with the alkaline reign, therefore employ volatile alkalizing agents such as ammonia in combination with hydrizne to elevate the feed water Ph to a level > ph 9.0 .

The addition of hydrazine serve the dual function of an alkalizing agent as well as on oxygen save energy thus lowering the level of corrosion. The anodic dissolution of iron in low carbon steels is nominal at pH 9.5 provided the totally demineralized water is available ammonia concentrations required to reach this high degree of alkalinity would be detrimental to the copper tubes of the condenser because of dissolution of copper, thus imposing an upper limit of ph 9-9.3.

24

CONDUCTIVITY MEASUREMENT

The electric conductivity measures the transport of electric change in any field. In metal conductors the current flows by transport of electrons where as in solution it flows by transportation such as Na+ and Cl- in which the higher transport of charges is the conductance of the solution.

Conductivity is the capacity of a solution to conduct current.

In solution conductivity is more complicated than in conductors because several species ensure the transport of charge for instance in drinking water the conductive species registered are sodium, calcium, magnesium, ferrous cations, ferrites phosphates and nitrate iron for slightly concentrated solution. The concentration of H+ protons and hydroxyl OH- ions can no longer be neglected. Therefore leads to a non-liner variation of conductivity / concentration.

ATRS [Automatic Turbine Run Up System]

Introduction

Turbine start up is the most difficult operation. Each start up will be different. Many parameters and procedures have to be scrupulously adhered to, as an error in human decision will result in heavier damage to the unit. Therefore modern day machines of higher capacity or machines ,which are to be started frequently ,are to be provided with automatic run up synchronizing loading gears.

Under normal condition this gear will accelerate the turbine from barring gear speed

uninterrupted at a rate determined by the initial turbine temp. condition. Under hot start condition ,this run up period may be of order of 5 to 10 minutes and comprises two zones ,the first half is relatively slow rate up to 1000rpm ,the second half is a fast rate from 1000 to 3000 rpm ( a range which includes critical speeds ). In the event of abnormal condition this program of acceleration is temporarily held (except in the regions of critical speed ),or in more severe conditions, reserved or tripped.

The turbovisory instruments moniter the abnormal condition. The gear if selected for the function also effects automatic synchronizing . this scheme matches the frequency voltage and time phase of generator output to that of existing bus bar and close the circuit braker.

Automatic loading gear enables the machine to be loaded automatically at the selected rate ,through the control of governor speed motor. The supervisory gear also will be in use during this function. The rate of loading varies widely from 5% per minute during the initial block loading to 20% M.C.R.. and also condition of the plant when the cold or hot start.

28

All control function related to turbine is realized by microprocessor based PROCONTROL ATRS System. This is based on user-friendly programming language p10 .The system is devided in three sub groups :-

1. SGC-OIL

It consist of three types of oil pumps:

1. Auxillary oil pump – 2 AC

2. Emergency oil pump- I AC & I DC

3 Jacking oil pump – 1 AC & 1 DC

Its function is:- Estabilishing lubricating oil & jacking oil supply.

Putting the turbine on barring gear speed.

Taking of JOP when sufficient speed is achived.

Taking of AOP when turbine main oil pump has taken over.

WHICH OIL PUMP WORKS AT DIFFERENT SPEEDS OF TURBINE?

2. SGC-CONDENSOR & EVACUATION

Condensate evacuation pump & vaccum operation.

It comprises of keeping at leat one of the two CEP’s in operation & evacuation the non- condensate gases from the system, maintaining the desired level of condenser pressure when turbine is in operation.

3. SGC-TURBINE

It is used for automatic synchronization of machine to the grid. Procontrol requires serial data exchange confined to the electronic room, process computer and control room.

PROCONTROL has following basic type of electronic modules:-

Individual Control Modules- These implemented to control, supervise,moniter protect individual valves ,pumps fans etc. modules equipped with a microprocessor built in i/o and dedicated control entity to control element. A serial i/o interface to the local bus to receive process signals required for interfaces & permissive logic. Hardware inter face is also requires to control room. Modules are AS45 ,AS46,AS47.

Programmable Processor – this module used for automation and superimposed on the individual control modules and allows building control, protection and alarms. Module is –PR05.

Input / Output Modules - various modules for input/output capabilities and connected to local bus. These modules can handle single, double throw contacts thermocouple, RTd’s milliAmp. signals etc. or to provide milliAmp. voltage electronic contact output signals.

FURNACE SAFEGUARD SUPERVISOR SYSTEM

This system is designed to ensure the execution of a safe, orderly operating sequence in start up & shut down of fuel firing equipment & to prevent errors of omission & commission in following such a safe operating procedure. This system takes care that every increment of fuel input corresponds to the available ignition energy inside the furnace. The following functions are entrusted to such end automatic burner management system:

1) Furnace purge supervision2) Igniter control3) Secondary air damper control4) Flame scanner intelligence5) Boiler trip protection

This system includes:

1) All Boiler Protections

(a)All Id Fans Off

Id (included draft) Fans suck the flue gases to the chimney through ESP. so if no ID fan is on the flue gases can’t be let out of yhe boiler. As the such here we give up a trip command.

(b)Both FD fans off

Fd (Force draft ) fans bring air to the furnace for combustion of coal. If no air is let in the furnace then complete combustion of coal does not occur.

NOTE:- There is a general principle i.e. fans On are to be greater or equal to FD fans are ON.

(c) Furnace Pressure

MAX – 150mmwcl MIN - -175mmwcl

If furnace is generally kept at 10mmwcl. If furnace is high all gases will gush out from all side. If low furnace will contract.

32

(d) Drum level

MAX - +250mmMIN - -250 mm

If drum level is very than steam formed will be more wet and may lead to more work for dryers. Wet steam may cause corrosion of turbine blades. If very low level than water is insufficient and may cause melting of boiler tubes.

(e) Unit Flame Failures

If the flame is not available then the boiler trips .

(f) Loss of All fuels

If there is no fuel available then the boiler trips.

(g) Air Flow<30%

Air flow from FD fans & PA fans combined should be more than 30% of maximum required.

(h) Re-Header Protection

Re header is located in the hottest part of the furnace. If the steam from HP TURBINE i.e. CRH line is not able to go reheater due to HP bypass closed and HPCV (high pressure control valve) closed ,then reheater can’t get steam and it’s tube may get melted. Similarly, if IPCV (intermediate pressure control valve) is closed then LP

Bypass is used to divert steam from HRH line (hot reheat line ) to condenser. also if GCB(grid circuit braker) opens then hp bypasss is opened.

(i) 24/220 V DC Supply

It is necessary for the system working i.e.24 V for the control panel and alarm system while 220 V for oil firing system.

33

2) Oil Firing System

We have got their levels/elevation from where oil is fired

AB --> heavy oil & light oil firingCD -->only heavy oil firingEF -->only heavy oil firing

Unit is light up using LFO with air. After –ward it is continued using HFO with steam. At diff. levels we have the ignition system to ignite oil. We are also having flame scanners. which monitor thr local fireball in the furnace. This system works on 220 V DC ans solenoids are present.

3) Soot Blower Control System

As the coal burn a large amount of ash is generated which clings to the wall & outer surface of tubes so we have a number of soot blower to blow the soot as it reduces thermal efficiency of tubes.

4) Secondary Air Damper Control(SADC)

It is based on tangential firing concept so as to create an imaginary fireball such that oil ,air & coal mix properly. It controls 6 nos: of fuel(coal) air dampers (A,B,C,D,E,F elevation),3 nos: of fuel(oil) air dampers(AB,CD,Ef) & 6 nos: of auxillary air dampers(AB,BC,CD,DE,EF,FF elevation) & 2 nos: of over fire dampers (lower & upper).

These dampers help in proper combustion by supplying air using FD fans to the furnace, which can be controlled using dampers/flaps. These auxillary air dampers maintain a predetermined set differential pressure between furnacre & wind box.

5)Auxilary Pressure Reducing Desuperheating (APRDS)

There are many places where steam is required like raising temp. of HFO & LFO system etc. the steam for these is obtained by taking a tapping from main steam. As the main steam is at pressure 145kg/cm2 & temp 540 C. the steam required is to be at 11 kf/cm2 & temp 340 C . so we have to both reduced temp & pressure. This is achieved by spraying water ,which helps to reduce temperature.

34

FURNACE PURGE

It is required after a boiler trip out ,before relighting the boiler ,to expel all unburnt fuel particles, vapour etc. from the boiler so that when is introduced during light up ,possibilities of an explosion are avoided. Till the boiler is purged no fuel mu
