water heat recovery boil

Heat Recovery from Boiler Blowdown TDS Control Only. Boiler water is blown down to control the amount of total dissolved solids (TDS) in the boiler. This water is pressurised, hot and dirty, creating large volumes of flash steam and possible disposal problems. A heat recovery system can reclaim large amounts of energy during this essential process.

blowdown calculation for boiler - altr

BLOWDOWN CALCULATION FOR BOILER - Altr

B = Blow down (m3 / hr) C = Maximum permissible concentration of solid inside the boiler drum B = E x S (m3 / hr.) C – S % B = S C – S This formula has been equally applied to control individual constituents in boiler. Blow down means, “lost heat”. This is because any water, which is getting drained from the boiler drum, will be at the saturation temperature of steam
