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 systems will usually result in a payback in a few short months from fuel savings alone.
Recovers 90% of heat 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
