Wilson Engineering’s CBHR is a low cost continuous blowdown heat recovery system that saves enough energy to pay for itself in just a few months. Flash is directed to the deaerator, remaining heat is transferred to the makeup water with a brazed plate hx. No source of power or air is required, this system is totally self contained.
The flash receiver shall be ASME rated for 50 psig. Internal design shall insure complete separation of the boiler blowdown effluent from the flash steam. For inspection and cleanout, a 4” x 6” hand hole will be provided.
Level control shall consist of a cast iron float and thermostatic (F&T) steam trap on the discharge of the heat exchanger. The F&T trap will continuously modulate cooled condensate to drain by maintaining the desired level in the flash vessel. Internal materials shall be 304 stainless steel with stainless steel seat and stainless steel valve.
