Heat recovery system with flue gas purifying - uses twin circuit gas-water double transformation stage with heat pump and intermediate heat carrier stage

摘要

The two-circuit appts. for flue gas purifying and recovering heat from the burners using oil, gas, coke or other fuel has an air/water heat exchanger connected to a water/water heat pump. The appts. uses a refrigerating circuit completely separate. The exhaust gas heat exchanger slopes down to a condensate trough, preceded by a droplet separator. The exchanger is connected to an evaporator. Additional heat, e.g. from exhaust water exchangers or solar collectors, can be introduced via valves, also used for filling and emptying the system. The refrigerator circuit has an evaporator, compressor and condenser. A high pressure meter monitors the hot gas side, with a second meter, controlling the low pressure side.
