Suratgarh Thermal Power Plant has a total installed capacity of 1500 MW and is located 27 km from Suratgarh town in Rajasthan. It has 6 stages of 250 MW coal power generation and 2 additional under construction stages of 660 MW each. The plant uses pulverized coal from local sources which is milled and fired into boilers to produce high pressure steam. This steam powers steam turbines which drive generators to produce electricity. The plant has won several national awards for its high performance standards.

A SEMINAR PRESENTATION ON SURATGARH SUPER THERMAL POWER PLANT By: RAHUL DABI MECHANICAL FINIAL YEAR 2015-2016
SURATGARH THERMAL POWER PLANT .
INTRODUCTION 1. Suratgarh thermal power station is the first super thermal power Station of Rajasthan with total installed capacity of 1500 MW and 93% PLF. 2. Suratgarh super thermal power station is located 27 km away from Suratgarh town in shri Ganganagar Dist. 3.This station is operated and maintained by ‘Rajasthan vidyut Utpadan Nigam Limited’.
S.S.T.P.S. is designed in six stages •STAGE I - 1x250 MW •STAGE II - 1X250 MW •STAGE III - 1X250 MW •STAGE IV - 1X250 MW •STAGE V 1X250 MW •STAGE VI - 1X250 MW •STAGE VII- 1X660MW(Under construction) •STAGE VIII- 1X660MW(Under construction) Total Power Generation - 1500 MW
YEAR ACHIVEMENTS 1999-2000 : Meritorious production & 3.74 lacs money 2000-2005 : Gold shield awarded by Ex President of India Late Mr. A.P.J. Abdul Kalam. 2005-2006 : Bronze shield awarded by Ex P.M. of India Dr. Manmohan Singh.

STEAM BOILER The boiler installed in S.T.P.S. are single drum, water tube naturally circulated over hanged, pulverizing coal firing with a max. Continuous steam output of 37 tons/hour at 138 kg/cm2 pressure and 5400C temperature. Heat transfer section in boiler : Furnace : Furnace is the primary element part of the boiler where the thermal energy is obtained by combustion.
BOILER: Flue gases Boiler water tubes & various stages Boiler furnace Pulverized coal Air from environment via draft fans Ash handling plant DM water Super heated steam stack
BOILER AUXILLARIES SUPER HEATER: Superheats are meant to raise the tem. of steam by absorbing heat from flue gases steam. Reheater: Reheater are used to raise the temp. of steam from which point the energy had been extracted in H.P. turbine . Reheating is continuing till temp. of steam is reaches to 5400C. Superheaters and reheaters tubes are made of 50 to 75 mm outside diameter.
Economizer : The function of an economizer in a steam-generating unit is to absorb heat from the flue gases and add this as sensible heat to fed water. It acts like feed water heater. The size of economiser tubes are 45 to70mm in outside diameter . Air Preheater: Air preheater is a heat exchanger in which preheating of air done by transferring heat from the flue gas before supplying to the combustion chamber. For better combustion the air temp. 250 to 350 is always desired. The preheating of air results: 1.Improved combustion 2.Saving in fuel consumption 3.Thermal efficiency.

STEAM TURBINE Turbine is a prime mover in which a shaft is rotate by impact or reaction of stream upon blades of a wheel. It converts the potential or kinetic energy of the steam into mechanical power. When the working substance is steam it is called the steam turbine. IMPULSE TURBINE: The passage of steam through moving part of turbine in such a manner that the pressure at the outlet side of the blade is equal to that at the inlet inside. Such a turbine is broadly termed as impulse turbine. IMPULSE REACTION TURBINE: Pressure of the steam at outlet from the moving blade may be less than that at the inlet side of the blades; the drop in pressure suffered by the steam during its flow through the moving causes a further generation of kinetic energy within the blades and adds to the propelling force which is applied to the turbine rotor. Such a turbine is broadly termed as ‘impulse reaction turbine’.

HIGH PRESSURE TURBINE: The HP turbine consists of 25 reaction stages. The moving and stationary blades are inserted into appropriately shapes into inner casing and the shaft. INTERMEDIATE PRESSURE TURBINE: The steam from HP turbine after reheating enters the inner casing from above and below through two inlet nozzles. The IP turbine consists of 20 reaction stages per flow. The moving and stationary blades are inserted in appropriately shaped grooves in shaft and inner casing. LOW PRESSURE TURBINE: Steam admitted to LP turbine from IP turbine flows into the inner casing from both sides through steam inlet nozzles.
