BLOWDOWN CALCULATION FOR BOILER | v p - …

The blow down is the water removed from boiler to maintain the solids level in the boiler drum. This can be calculated as follows: 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
