Boiler Blowdown and heat recovery - energypurse.com

Blowdown is the process of removing these impurities by draining some of the water from the boiler. A small amount of water is drained continuously from the surface of the water inside the boiler. Water is also drained periodically from the bottom of the boiler. Due to the level of impurities, bottom blowdown is not used for heat recovery.
