BLOWDOWN CALCULATION FOR BOILER - Altret

2019-4-17 · E = Evaporation or steam generation rate. S = Amount of solids (ppm) 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".
