forced circulation type water tube boiler

Natural Circulation in Boilers - venus-boiler.com

The water is forced through the economizer by the boiler feed pumps. Superheaters add heat to steam. That is the heat is added to steam leaving the Boiler steam drum /Boiler shell. The steam passes through the superheater tubes by virtue of the boiler operating pressure. Evaporators may be multi tubular shell, Waterwall tubes, Boiler bank tubes
