History of Power Development in RajasthanRajasthan 1949; 19 princely states merged.

Total number of towns and villages electrifiedMax 42.

Installed generating capacity 13.27 MW.

Rajasthan State Electricity Board (RSEB) formed 1st July 1957 and

development of power sector started.

Under new Power Reforms Undertaken by State Government, RSEB was

unbundled into five Power Companies in July 2000.

Rajasthan Rajya Vidyut Utpadan Nigam Limited (RRVUNL) is one of them.

RRVUNL is also managing and operating the following Inter State Projects (ISP)

S.No Power Station Present Capacity

01. Rana Pratap Sagar Hydel PS (4X43 MW) 172 MW

02. Jawahar Sagar Hydel PS (3X33 MW) 99 MW

Total 271 MW

Introduction of RRVUNL

RRVUNL has been entrusted with the job of development of power projects

under state sector, in the state along with operation & maintenance of state owned

power stations.

Present Installed Capacity of RRVUNL is 7277.35 MW and 271 MW (ISP).

INNOVATIVE PROJECTS SUMMARY1. Erection of Isolation Gate at PA Fan Discharge Duct (FY 2018-19)

Impact:- Recently in Dec 2019 one PA fan of Unit#1 was under

breakdown for 15 days and with the help of this recently erected gate

Unit run continuously on 60-70% load instead of shutdown the Unit and

the damaged fan was attended in parallel.

2. Refractory Works in Economizer and LTSH Bends (FY 2017-18)

Perforated Plates (size-600X25X6MM) covered by refractory for

protecting bends from erosion due to flue gases.

Impact:- BTL due to erosion of bends from flue gases has been

controlled.

3. Shielding Plates in Heat Recovery Area (FY 2017-18)

Impact:- Erosion of bends from flue gases has been controlled.

INNOVATIVE PROJECTS1. Erection of Isolation Gate at PA Fan Discharge Duct FY 2018-19

Problem:-

During running of Unit, If any

one PA Fan goes under

breakdown, It required to be

isolated to attend the problem.

With available discharge

damper it was not possible to

isolate the PA Fan completely.

Due to Passing of air from

discharge damper PA Fan under

breakdown rotates in reverse

direction, due to which

maintenance work was not

possible and also it hurdles

when again PA Fan is required

to be taken in service.

Investment (Rs. In Lakhs):- 23.524

Annual savings (Rs. In Lakhs) :- 5873.76

(Estimated)

Replication Potential :- Can be explored by

other plants also if they are also facing such type of

problems.

2. Refractory Works in Economizer and LTSH Bends

(FY 2017-18)

Problem:- Erosion in bends could

cause BTL.

Investment:- Rs. 1.0 Lakhs.

Estimated Annual Saving:- Rs. 5484.371 Lakhs

Replication Potential:- Yes. Can be explored by other plants

also if they are having high BTLs in Economizer and LTSH Bends.

Action Taken:- Covered porous plate

(perforated plate of size-600X25X6MM) in

economizer and LTSH area by refractory.

INNOVATIVE PROJECTS3. Shielding Plates in Heat Recovery Area (FY 2017-18)

Project Details

Problem Action Taken

During Annual Shutdown while

carrying out De-metering of

Tubes and Bends in Heat

Recovery Area, It had been

Observed that Tubes and Bends

started eroding due to Impact of

Flue Gasses.

Provided SS (Stainless Steel) shielding

plates on tubes & bends in front Heat

Recovery Area for protecting erosion

of tubes and bends due to flue gases.

This arrangement was not provided by

OEM in original design.

Investment:- Rs. 3.38 Lakhs.

Estimated Annual Saving:- Rs. 3656.25 Lakhs

Replication Potential:- Yes. Can be explored by other plants also.

OTHER MODIFICATIONS1. Modification Done in Wet Bottom Ash Hopper (BAH) to avoid damage of

Refractory and Seal Trough

Original Drawing of BAHOEM -M/s Macawber Beekay Pvt. Ltd, Noida.

In consultation with OEM

Page 23: KALISINDH THERMAL POWER PROJECT, RRVUNL, JHALAWAR … · Suratgarh Supercritical Thermal Power Station U# 7 660 MW 2. Suratgarh Supercritical Thermal Power Station U# 8 660 MW Total

Problem

Whenever Clinkers fall in Bottom Ash Hopper, It causes damage of refractoryon walls of bottom ash hoppers & seal trough due to explosion occurred bysplashing of water on the refractory of walls.

Impact

Frequent Occurrence of this phenomenon leads disturbance in furnace, whichfurther causes drastic variation in draft making Units unstable and prone totripping.

Sometimes this phenomenon may become cause of accident and human injuryalso.

23

OEM suggestion

Additional strengthening (by MS/SS angles, plates stiffeners & SS anchors

etc)

Result

Refractory of said portion has been carried out in both units but the problem

remains the same.

Result:- Frequent problem of damage of bottom ash

hoppers walls, seal trough, refractory etc. was resolved.

Our Observation

Main problem in the existing design

was rectangular portion of Bottom Ash

Hopper. At the time of explosion water

of bottom ash hopper spreads & strikes

on the walls of rectangular portion and

seal trough which resulting damage of

refractory of walls & seal trough of

bottom ash hopper.

Modifications done

The bottle neck portion of

bottom ash hopper was

minimized to provide

path/space (by providing

taper plates) for water

splashing during the falling of

clinkers in bottom ash

hoppers.

OTHER MODIFICATIONS1. Modification Done in Wet Bottom Ash Hopper (BAH) to avoid damage of

Refractory and Seal Trough

PROJECTS IMPLEMENTED THROUGH KAIZENSupervisor Level

Investment:- Rs. 2.0 Lakhs

Annual saving :- Rs. 5342.381 Lakhs.(Estimated)

Problem:- BTL observed 6 times in two

Financial Years due to misalignment of tubes and

bends of economizer & LTSH zone.

Action Taken

Implemented at site in year 2019.

Observation

All tubes remained aligned and BTL

also controlled in these zone.

1. Boiler Area

Proposed Solution

Providing U-Clamps upon these tubes

and bends, for preventing tubes and

bends to be misaligned and henceforth

to be eroded due to flue gasses.U- Clamps

Annual Saving in APC:-10.78 MU (Rs. 2.97 Crores) and

running operation/maintenance cost of compressors also reduced.

(Saving of APC)

OEM Design

Installed =15 Nos. (11 Nos. working + 4

Nos. Stand By).

Supervisor observation & Suggestion

Daily pattern of loading/unloading hours of

running compressors and suggested to reduce

the nos. of compressors in service. Now only 8

Nos. compressors are running on full load & 7

Nos. compressors on partial load.

Annual Saving

4.91 MU.

Same practice adopted for Instrument & Service Air Compressors

Annual saving :-5.87 MU.

Pollution Control Board

Guideline

Zero liquid discharge.

Suggestion

Modify existing drainage system

of BTG area.

Action Taken:- Some drainages/trenches have

modified and water transferred to already existing

boiler-ESP drain sump then tube settler for

clarification then finally this water is transferred to

HP/LP suction pit for use of bottom overflow &

bottom De-Ashing of Units.

Result:- Saving in fresh water consumption

besides helping in achieving Zero Liquid Discharge.

BEST PRACTICES ADOPTED AT KATPP

Previous Running of MDBFP during Cold

Start Up :- 20 to 23 hours

Practice Changed:-

In Current year only one TDBFP are being

run during cold and warm start up of units

in place of MDBFP if one unit is running

already to reduce APC.

Only two compressors are being kept in

service (1-SAC & 1-IAC) in place of

earlier practice of 3-nos. for reduction of

APC.

One CWP pump has been taken out from

service for full winter season and only two

CWPs are being run per unit (without

sacrificing vacuum) in place of earlier

practice of 3-nos.Reduction in APC.

BEST PRACTICES ADOPTED AT KATPP

All 03 Nos. of CPU are being

taken in service during unit start

up of unit which has reduced

time of DPR and helped in early

normalization / achieving full

load of unit.

Monitoring and Supervision at the time of turbine rolling and heat soaking

Maintaining controlled firing rate/ heat input

Result

Unit is being synchronized in 10 to 12 hours in comparison to previous

years’Unit synchronization time of 15 to 18 hours during the cold start up.

Reduction in Unit start up

and synchronization time,

during hot as well as cold

Start Up

Passing of steam through high energy drains to

condenser and to start up flash tank/ IBD have been

arrested / minimized.

More valves are being replaced immediately.

Reduced

Energy Losses
