In A Steam Power Plant The Heat Supplied To The Boiler Is 3X106 J Kg The Heat Rejected By The Cooling Water In The Condenser Is


Steam engine - Wikipedia

A steam engine is a heat engine that performs mechanical work using steam as its working fluid. whereas river water can be re-used. In all cases, the steam plant boiler feed water, which must be kept pure, is kept separate from the cooling water or air. An History· Components and accessories of steam engines· Engine configurationRoll of Feed water Heaters in 120 Mw Thermal Power Plant· PDF It supplies cooling water to the turbine condenser and thus acts as a medium through which heat is thermal shock to the boiler metal when In a steam power plant (usually modeled as a modified Rankine cycle) feed water heaters allow the feed water to be
