THIS PRESENTATION IS PRENSENTEDBY SWAI SINGH ONRGTPPINTRODUCTION OF RAMGARHGASTHERMAL POWERPLANTRAMGARH GAS THERMAL POWER PLANT IS THE FIRST GAS THERMAL POWER PLANT OF THE RAJASTHANTHE PRESENT INSTALLED CAPACITY OF RGTPP IS 270.50 MW.RGTPP IS LOCATED NEAR RAMGARH TOWN AT ABOUT 60 KM FROM DISTRICT HEAD QUARTER, JAISALMER (RAJ.)

THREE STAGE IN THIS PLANT :- FIRST STAGE IN THIS STAGE ONLY ONE GAS TURBINE [GT-1 35.5 MW] STARTING ON 12.01.1996SECOND STAGE THIRD STAGE IN THIS STAGE ONE GAS TURBINE [GT-2 37.5 MW] STARTING ON 07.08.2002 AND ONE STEAM TURBINE [STG-1 37.5 MW] STARTING ON 25.04.2003IN THIS STAGE ONE GAS TURBINE [GT-3 110 MW] STARTING ON 20.03.2013 AND ONE STEAM TURBINE [STG-2 50 MW] STARTING ON 05.04.2014AT RGTPP GAS TO THE TURBINES IS BEING SUPPLIED THROUGH GAIS AUTHORITY OF INDIA LTD. FROM ONGC AND OIL INDIA LTD. IN RGTPP REQUIREMENT OF WATER IS SUPPLIED THROUGH SAGAR MAL GOPA BRANCH OF IGNP (INDIRA GANDHI NAHAR PROJECT)THE QUANTITY OF THE GAS IS 6-8 LAC SCM PER DAY FROM GAIL TERMINAL POWER PLANT CYCLE RAMGARH GAS THERMAL POWER PLANT IS COMBINED CYCLE POWER PLANTTHE GAS TURBINE IS OPERATED ON BRAYTON CYCLE PRINCIPLEANDTHE STEAM TURBINE IS ROTATED ON RANKINE CYCLE PRINCIPLE.

Gas turbines are described thermodynamically by theBrayton cycleIn this cycle:1-2 Isentropic compression (in a compressor)2-3 Constant pressure heat addition (in a combustor)3-4 Isentropic expansion (in a turbine)4-1 Constant pressure heat rejectionBrayton cycle

Steam turbine are described thermodynamically by the Rankine cycle. This cycle follows the idea of the Carnot cycle but can be practically implemented.In this cycle :4-1 isentropic pump 1-2 constant pressure heat addition2-3 isentropic turbine 3-4 constant pressure heat rejection

GAS TURBINEGAS TURBINE ANIMATION

1. COMPRESSOR

The atmosphere air is compressed to the 17 stage compressor and before it passes through the filter . The compressor ratio is 10 and this is routed to the combustors .

2. COMBUSTORSThe fuel (gas) is provided to ten equal flow lines ,each terminating at a fuel nozzle centered in the end plate of a ten separate combustion chamber and prior to being distributed to the nozzles ,that fuel is actually controlled at a rate consistent with the speed and load requirements of gas turbine . The nozzle introduces the fuel into the combustion chambers where it mixes with the combustion air and is ignited by the spark plugs . At instant when fuel is ignited in one combustion chamber , flame is propagated through connecting crossfire tubes to all other combustion chamber . 3. TRANSITION PIECES

The hot gases from the combustion chambers expand into the ten separate transition pieces and from there to the three stage turbine section of the machine. 4. TURBINE

There are three stage of the turbine and each consists of a row of fixed nozzle row, the kinetic energy of the jet is increased with an associated pressure drop and in each following row of a moving buckets, a portion of the kinetic energy of the jet is absorbed as useful work on the turbine rotor. 5. EXHAUST

After passing through the third stage buckets , the gases are directed into the exhaust hood diffuser which contains a series of turning vanes to turn the gases from an axial direction , thereby minimizing exhaust hood losses. The gases then pass into the exhaust plenum and are introduced to atmosphere through the exhaust stack or to the HRSG .EXHAUSTSTEAM TURBINE

STEAM TURBINE The HP Steam Turbine is drawn from HP steam header of HRSG 1 & 2. The HP Steam parameters of the HP steam are 60 kg/cm2 pressure and 480 deg C temperature . The LP steam to turbine is drawn from LP steam header of HRSG 1 & 2 . The LP steam parameters of LP steam are 4.3 kg/cm2 and 148 deg C temperature .

Heat recovery steam generator(hrsg)

HRSG is a horizontal, natural circulation, bid ru, dual pressure unfired water tube boiler . It is designed to generate HP steam at 62 kg/cm2 pressure and 483 deg C temperature with 59.9 t/hr steam flow .LP steam is generated at 5 kg/cm2 pressure and at saturated temperature with 10.9 t/hr steam flow . These HRSGs are having facilities of HP and LP bypass system 100% for both the circuits to match the rated parameters (pressure and temperature) while starting the HRSGs and to minimize the losses of water and heat while shutting down the m/c . These are also useful when STG trips and to keep boiler in service . Major equipment of recovery boilers are : Diverter damper and its seal air fan , Super heater , Evaporator (HP & LP) , Economizer (HP-1 ,HP-2 & LP) , CPH , Stack (height) .COOLING SYSTEM OF RGTPP

CONTROL ROOM OF RGTPP

Various measurements are taken at the control room simultaneously. In RGTPP two control room. One control room is used for GT-1, GT-2 and STG-1. Second control room is used for GT-3 and STG-2.

All parameter like pressure, temperature, turbine speed etc. Is finding in control room. In control room valve of all parameter is seen at different computer, so control room is comprised or panelisem room. After analyzing the RGTPP 270.50 MW combined cycle power plant, we can describe that this power plant is a very efficient one as compared to other power plants in its series. Also, we would like to add up that it is very compact in size, less pollutive to nature, easily controlled & decent power plant that we had ever seen. We really had nice time here & got a treasure of practical knowledge from the RGTPP employees. In future we are sure that this vocational training in RGTPP is going to help us in our rest of the studies.CONCLUSIONRAMGARH GAS THERMAL POWER PLANTOVERVIEW
