Pumps Selection & Sizing - Industrial steam

Pumps Selection & Sizing. The ASME code requires that the boiler feed pump be able to put water in the boiler at the evaporation rate at a pressure which is 3% greater than the highest setting of the safety valves. If the boiler in this example is designed for 150 psig operating pressure, the safety valves could be set at 175 psig.

Boiler blowdown - Wikipedia

Boiler blowdown is water intentionally wasted from a boiler to avoid concentration of impurities during continuing evaporation of steam. The water is blown out of the boiler with some force by steam pressure within the boiler. Bottom blowdown used with early boilers caused abrupt downward adjustment of boiler water level and was customarily expelled downward to avoid the safety hazard of
