Waste heat recovery - Alfa Lav

2016-10-25 · Process heat is usually generated in steam boilers and/or in fired heaters/furnaces. In both cases, waste heat recovery can lead to substantial fuel savings. Process heat from steam boilers Recovering waste heat often reduces the need for steam in a plant. Consequently the boiler's fuel consumption is reduced, as are

Boiler blowdown - Wikiped

2019-10-15 · 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
