BLOWDOWN CALCULATION FOR BOILER - Altret

steam can occur. To prevent boiler tube chocking and overheating of the boiler tubes the blow down is necessary. 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)
