how to reduce hot water boiler exhaust flue gas

Experimental investigation on vapor-pump equipped …

The exhaust flue gas temperature is in range of 28–32 °C when the ambient air temperature changes in range of 10–18 °C. The system performance is relatively stable. To further reduce the exhaust flue gas temperature, multistage heat exchanger or rotary wheel heat exchanger may be used. 2.
