Blowdown Heat Recovery

Boiler Blowdown Systems

  • For steam applications
  • Captures waste heat from blowdown process
  • Maintains desired level of total dissolved solids (TDS)
  • Up to 22 gpm blowdown water
  • Up to 180 gpm makeup water


Continuous boiler surface blowdown heat recovery (BDHR) is the most effective method of purging destructive solids from any steam boiler system, while also using the energy from the heated blowdown water to pre-heat the make-up water.

  • Product Overview
  • Related Resources
  • Applications
  • Recovers 90% of energy normally lost
  • Automatically controls surface blowdown flow to maintain desired concentration of dissolved solids within the boiler
  • Compact size for convenient placement
  • Transfers the blowdown heat to the makeup, thereby decreasing fuel costs; nearly 100% efficiency at all operating points
  • Saves chemical costs by reducing blowdown


The BDHR automatically controls the surface blowdown to maintain the desired level of total dissolved solids (TDS) in the boiler, reducing the amount of blowdown to a minimum. It also recovers the heat from the high-temperature blowdown and transfers it to the incoming cold makeup water, maximizing boiler efficiency.

The blowdown heat recovery system will usually result in a payback in a few short months from fuel savings alone.
