Boiler blowdown - Wikipedia

Boiler blowdown. 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

Flue gas temperature or flue gas loss | Bosch steam …

The flue gas temperatures at the boiler outlet are normally roughly 60K above the temperature of the product inside the steam boiler. At an operating pressure of 10 bar, which corresponds to a saturated steam temperature of 185°C, the flue gas temperature is therefore roughly 245°C. This corresponds to a flue gas loss of roughly 11%.
