- For steam applications
- Captures waste heat from blowdown process
- Preheats cold makeup water
- Up to 22 gpm blowdown water
- Up to 180 gpm makeup water
- Efficient baffling separates the dirty blowdown water from the clean steam
- Transfers the remaining heat normally lost during blowdown to the cold makeup water as it flows to the feedwater heater
- Consists of an ASME-approved and stamped flash tank and a blowdown heat exchanger
- Compact, low-cost alternative to the shell and tube design
- Heat recovered as flashed steam
In addition to the heat recovered as flashed steam, the heat exchanger will transfer the remaining heat normally lost during blowdown to the cold makeup water as it flows to the feedwater heater. The systems quickly pay for themselves with fuel savings resulting from using heat that would otherwise be wasted. The model AHR is a coil-type, flash tank heat exchanger. It is a compact, low-cost alternative to the shell and tube design, while still offering waste heat recovery to pre-heat make-up water, reducing operating costs for the system.
- 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
- 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
- Recovers 90% of energy normally lost
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. 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.
