&he overall re@uirement of steam for the plant is a/out ++,

day.

&he two 5eat ?ecovery Ateam 0enerator of capacity 8, t

provide , tonne of steam re@uired.

&he remaining is generated inside the water tu/e /oiler. %oileload of changing re@uirement of steam inside the plant.

&he steam generator is designed to fire 5A>$ LA5A=FO$and '0 with four set of oil and gas com/ination

/urners.

Bxhaust gas from the gas tur/ine is used in the 5?A0 to

generate steam.

STEAM GENERATOR$BOILER%

&he steam generator comprises a water cooled furnace$

convection /an"$ steam and water drum$ headers fo

collecting and distri/uting water and steam$ primary ansecondary super heater$ framed$ casing insulation etc.

It ta"es up the load of changing demand of steam in differen

operation performed inside the plant.

It also has a %oiler Feed water system to provide water odesired @uality to the /oiler for the generation of steam.

HEAT RECOVERY STEAM GENERA

A heat recovery steam generator or HRSG is an

recovery heat exchanger that recovers heat from a stream. It produces steam that can be used in a

process.

Two HSR generate !"# tonne of steam per hr.

It recovers heat from the f$ue gases coming from tturbine.

HRSs consist of four ma%or components& the econ

evaporator( Superheater and water pre heater.

GAS TUBINE POWER PLANT

The simp$e gas turbine power p$ant main$y consists of

turbine coup$ed to a rotary type air compressor and a com

or combustion chamber which is p$aced between the comp

and turbine in the fue$ circuit. Auxi$iaries( such as coo$in

water pumps( etc. and the generator itse$f( are a$so driv

the turbine. )ther auxi$iaries are starting device( $ubri

system( duct system( etc. A modified p$ant may have in ad

to the above( an inter*coo$er( a regenerator and a preheat
