| Abstract: | The diffusion of condensing boilers has been hampered by the fact that their efficiency advantages become significant only when reaching a low return.Particularly in the field of district heating,condensing technology has not been used due to the high return temperature.A new exhaust condensing heat recovery system for district heating with gas boiler is developed,in which absorption heat pump is combined with the gas boiler to recover exhaust condensing heat of the gas boiler,even the temperature of the return water for district heating is so low that the latent heat of vapor in the flue gas could not be recovered directly by the general condensing technologies. With this technology the heating thermal efficiency will be increased 10% that is 5% more than the general latent heat of vapor in the flue gas recovering technologies. |
