bund feed watter heater aamtaur parr khol aur tube heat exchanger hotey hain jahan feed watter tubes mein gujarta haye aur turbine nishkarshan bhaap dwara germ kiya jaataa haye. inhen ack khule heater key saath nikaale gaye bhaap key dabaav key liye feed watter koo badhaane key liye heater seey pahale aur baad mein alag pampon kii aavashyakta naheen hoti haye. haalaanki, nikali gaee bhaap (joe feed watter koo germ karane key baad lagbhag poori tarah seey sanghanit hoti haye) koo phir sanghanak dabaav mein thrott kiya jaanaa chaahiye, ack isenthalpic prakriya jisake parinamswarup samagr chakr dakshata parr thodaa dund key saath kuchh entropy laabh hotaa haih
kaee bijli sanyantron mein kaee feed watter heater shamil hotey hain aur way khule aur bund donon ghatakon kaa upayog curr sakate hain. feedwater heater kaa upayog jeevaashm aur paramanu-eendhan vaale bijli sanyantron donon mein kiya jaataa haye.
arth-saadhan.
ack arth-saadhan ack feed watter heater key samaan uddeshya puuraa kartaa haye, lekin takniki roop seey alag haye kyonki yeh germ karane key liye chakr bhaap kaa upayog naheen kartaa haye. jeevaashm-eendhan sanyantron mein, arth-nirdhaarak bhatti seey sabse cumm tapman vaali flue gais kaa upayog boiler mein pravesh karane seey pahale paani koo germ karane key liye kartaa haye. yeh bhatti aur feed watter key beach garmi hastaantaran koo ack chhote ausat tapman pravanata (poore bhaap generator key liye) mein honey kii anumati detaa haye. isaliye eendhan kii vaastavik oorjaa samagri key sambandh mein dekhane parr pranali kii dakshata mein aur vriddhi hoti haye. 
adhikansh paramanu oorjaa sanyantron mein ack arth-saadhan naheen hotaa haye. haalaanki, dahan engineering pranali 80 + paramanu sanyantra design aur isake vikaasvaadi uttaradhikari, (ee.jee. koria vidyut oorjaa nigam key aeye. pee. aar.-1400) mein ack abhinn feed watter economizer shamil haye. yeh arth-saadhan sabse cumm tapman vaale praathamik sheetlak kaa upayog karke bhaap generator key pravesh dwaar parr bhaap generator feed watter koo pahale seey germ kartaa haye.
