Pre-Heat Boiler Feed Water


A power plant generates steam for a neighboring paper recycling mill. Condensate could not be returned from the mill. Therefore, the power plant required an instantaneous supply of hot water to keep up with varying demands on the boiler. Space was limited making the use of bulky storage tanks or shell-and-tube heat exchangers impractical. Considerations needed to be made for high-pressure superheated steam supply.
