Constantly circulation, to room air heat, in cyclic process, due in flue gas contain a large amount of vapor, if by heat exchanger 1 with
The heat of cold water exchange is excessive, and the temperature of flue gas is likely lower than condensation temperature, and then condensation occurs, especially in combustion gas wall
When extension furnace is in Smaller load working condition, since the combustion power of burner 4 is small, the amount and temperature of flue gas are held with regard to small, therefore very
Condensation easily occurs in heat transfer process.
The burnt gas wall hanging furnace of the utility model at work, the aperture of gas valve is detected by gas valve aperture detection device
Size determines the load operating conditions of burnt gas wall hanging furnace, if aperture is lower than the 1/3 of total aperture, i.e. judgement burnt gas wall hanging furnace is in
Smaller load working condition, on the contrary it is big load operating conditions；When burnt gas wall hanging furnace is in Smaller load working condition, electronic cut-off is allowed
Valve opens 3 runner of isocon, flows through a part of water from isocon 3, and to reduce the water flow for passing through heat exchanger 1, flue gas is low
The heat that warm water absorbs is reduced, and the temperature of flue gas increases, meanwhile, in the case that in water outlet, 22 temperature is certain, using moisture stream,
So last water outlet 22 is hot water or cold water mixing, so the water temperature for flowing through heat exchanger 1 needs to be higher than 22 temperature of water outlet,
In this way when group setup temperature is identical, flue-gas temperature is high when can be than not shunting, and under this double action, steams the water in flue gas
The temperature of gas is higher than condensation temperature, therefore condensation will not occur；When being in big load operating conditions, electric check valve is allowed to close
3 runner of isocon is closed, to increase the water flow for passing through heat exchanger 1, improves the thermal efficiency.
