Thermal power station

A thermal power station is a power station in which heat energy is converted to electric power. In most places the turbine is steam-driven. Water is heated, turns into steam and spins a steam turbine which drives an electrical generator. After it passes through the turbine the steam is condensed in a condenser and recycled to where it was heated.

Biomass Boiler - an overview

The steam–water system consists of components that are used to convert water to steam. Feedwater is pumped from a feedwater tank to the boiler. Feedwater is heated in the economizers and enters the drum. Saturated water flows downward in tubes called downcomers to be divided and distributed. Evaporating water rises up the wall tubes.


The cooling water flows through the tubes and exhausted steam over the surface of the tubes. The steam gives up its heat to water and is itself condensed. Advantages of this type of condenser are: condensate can be used as feed water, less pumping power required and creation of better vacuum at the turbine exhaust.
