Steam Power Plant ConstructionWorking Advantages and ...

Aug 09 2016 · The steam gets condensed with the help of cold water from the cooling tower. The condensed water with the feed water enters into the economiser. In the economiser the feed water gets heated up before entering into the boiler. This heating of water increases the efficiency of the boiler.

How Does a Coal Power Plant Work? - Bright Hub Engineering

Dec 04 2008 · The first conversion of energy takes place in the boiler. Coal is burnt in the boiler furnace to produce heat. Carbon in the coal and Oxygen in the air combine to produce Carbon Dioxide and heat. Stage 2. The second stage is the thermodynamic process. The heat from combustion of the coal boils water in the boiler to produce steam.
