Boiler Blowdown
Blowdown is the controlled removal of water from a boiler to limit the build-up of dissolved solids. Each litre leaves at saturation temperature, carrying energy away, so well-controlled blowdown — and recovering its heat — is a direct boiler-efficiency lever.
Boilers concentrate dissolved solids as steam is drawn off; blowdown keeps water chemistry in range to prevent scaling and carryover. Controlling blowdown to the actual conductivity rather than a fixed schedule, and recovering heat from the blowdown stream with a flash vessel or exchanger, both cut fuel use.
