Steam Accumulator

a steam boiler with an increased capacity for heat accumulation and emission that results primarily from its increased water volume and is important for industrial boilers, which operate mainly with varying steam consumption. Upon an increase in pressure or the water level in the boiler (or both), excess heat is developed; as the pressure decreases (and the water in the boiler becomes superheated), the excess heat may be used for additional evaporation of part of the water from the water volume.
