per NEMA 23 and NEMA 24 is an impulse blow where steam is bottled up in the boiler attached to the opposite end of the steam piping to the steam turbine. A break out point at the steam turbine is established and a quick opening valve is attached to this break out and a short piece of pipe is attached to vent the steam in a safe direction.

Soot Blowing - an overview | ScienceDirect Topics

Steam Soot-blowers. Soot blowing is most commonly carried out using dry saturated or slightly superheated steam at boiler pressure. The use of dry saturated steam generally has a better impact effect in removing deposits than superheated steam, but precautions must be taken to preclude slugs of water from entering the boiler flueways.

Boiler blowdown - Wikipedia

2019-5-29 · 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
