Forced circulation boiler - Wikiped
The forced circulation boiler begins the same as a natural circulation boiler, at the feed water pump. Water is introduced into the steam drum and is circulated around the boiler, leaving only as steam. What makes the forced circulation boiler different is its use of a secondary pump that circulates water through the boiler. The secondary pump takes the feed water going to the boiler and raises the pressure of …Get a Quote
