If a boiler is to supply a given amount of steam, the water blown down must be in addition to this amount. The energy that is lost in blowdown is the energy that is supplied to the additional amount of water that is heated to saturation temperature, and then blown down. A close approximation can be obtained using steam
Boiler Blowdown of steam boilers is often neglected or abused. The purpose of boiler blowdown is to control solids in the boiler water.
