1 Suratgarh Super Thermal Power Station2

Suratgarh Super Thermal Power Station SURATGARH THERMAL POWER STATION IS THE FIRST SUPER THERMAL PLANT OF RAJASTHAN.

IT HAS INSTALLED CAPACITY OF 1500 MW POWER , WHICH IS HIGHEST IN THE STATE.SIX UNITS IN SURATGARH THERMAL POWER STATION AND EACH ONE OF THEM HAS CAPACITY OF 250 MW POWER .

(250*6=1500)MW

Water is heated, turns into steam and spins asteam turbinewhich either drives anelectrical generator . After it passes through the turbine, the steam is condensedin acondenserand recycled to where it was heated; this is known as aRankine cycle. Some prefer to use the termenergy centerbecause such facilities convert forms of heatenergyinto electrical energy.

COAL HANDLING PLANTCoal Comes from M.P.(Bilaspur) & Chhattisgarh.Raw coal is transported from coal mines by railways.Coal is unloaded from wagons by wagon tippler. 1. Wagons are rotated upside down through an angle of 180 degrees. 2. coal is manually crushed then it pass through crusher transported to crusher house with the help of conveyer belts.Crusher crushes coal to a size of 20mm.Then coal is sent to pulvarizing mill.

This plant can be divided into 3 sub plants as follows:-1) Flue and Ash Plant.2) Air and Gas Plant.3) Ash Disposal and & Dust Collection plantASH HANDLING PLANTUTILIZATION OF ASH1.Manufacturing of building materials.2. Making of concrete.3. Manufacturing of cement.4. Road construction etc.BOILER Water is converted into steam inside the boiler.

Coal is burnt inside boiler.

Generated heat is used to generate steam.

WATER TUBE BOILER are used in SSTPS.

HEIGHT OF BOILER :- 60METER

Technical Specification

1).Type Water Tube Boiler 2).Make BHEL3).Capacity 780 tones per hour4).Steam pressure 150kg/ sq. cm5).Efficiency 90%6).Steam temperature 550 deg.c

SUPER HEATER13Super heater is used to remove the moisture content from the steam.The steam at pressure 140 kg/m and 530 degree C is passed to the super heater from boiler drum.Super heater raises the temperature of steam above 540 degree C.Steam is passed to the hpt.Advantages of super heater 1. Increases efficiency 2. Reduces corrosion of turbine blades.ECONOMISER14Flue gases coming out of the boiler carries lot of heat.ECONOMISER extracts a part of heat from the flue gases and uses for heating the feed water.Thus improves efficiency of plant. Temp. inside ECONOMISER is about 315 deg c.

CHIMNEYChimney is used to leave the flue gases at proper height in the environment.Their height is so decided that flue gases cant affect area of about 50km.Content of flue gases are checked at different heights inside the chimney.

TURBINETurbine converts heat energy of steam into mechanical energy.

Kinetic energy is changed to mechanical energy.

Rotational speed is 3000rpm,15000rpm.

TYPES OF TURBINE

16 HP turbine having 25 blades & single flow.

IP turbine having 17 blades & single flow.

LP turbine having 8 blades & double flow.GENERATORGenerator converts mechanical energy into electrical energy.The generator is driven by directly coupled steam turbine at a speed of 3000 r.p.m.

Hydrogen is used for cooling medium primarily because of its superior cooling properties & low density.The purity of hydrogen should be 98% or above.17

COOLING TOWER Cool the warm water discharged from the condenser and feed the cooled water back to the condenser. Reduced the cooling water demand In the plant.
