Control Of Steam Boilers - hof-hicken.de

Steam boilers produce steam that flows through pipes from areas of high pressure to areas of low pressure, unaided by an external energy source such as a pump. Steam utilized for heating can be directly utilized by steam using equipment or can provide heat through a heat exchanger that supplies hot water to the equipment.

Boiler - an overview | ScienceDirect Topics

Stephen Hall, in Branan's Rules of Thumb for Chemical Engineers (Fifth Edition), 2012. Introduction. Boilers are essentially shell-and-tube heat exchangers, with water being boiled to steam or transformed to high pressure hot water. Heat is generated by burning a fossil fuel; the combustion gas can be ducted around tubes containing the water (water-tube boiler), or the hot gas can pass inside
