Boiler Blowdown Control | Eurotherm by Schneider Electric

Blowdown control can be broken down into instantaneous or continuous systems and may be manual, semi-automatic or fully automatic. Instantaneous manual system The simplest implementation of blowdown control is an instantaneous manual system that is operated once per shift to reduce the boiler total dissolved solids (TDS) to a sufficient level well below the boiler specified maximum limit.
