The air inducing pipeline, air-introduced machine, economizer bank；Wherein, high-temperature flue gas is extracted via air inducing pipeline by air-introduced machine,
The exhaust gases passes of air inlet economizer bank, are preheated to the air in air duct；Ring rib is added in outside the copper pipe of exhaust gases passes
To increase the heat exchange area of air and copper pipe, baffle plate is added in the outer tube of air duct and surveyed, to increase the flow of air flow.
The smoking tube head is the circle pipe enclosed around burner one, smoking tube head of being extended respectively from all directions into stove, each
Smoking tube head is uniformly distributed around the circle of burner one.
The heat-exchanger rig that a kind of gas-cooker high-temperature flue gas of the present invention is utilized includes smoking tube head, induced duct with guard
Road, air-introduced machine, economizer bank, economizer bank include exhaust gases passes, air duct, copper dividing plate and fin, stainless steel tube,
Air preheat pipeline section；Wherein, there is air inducing pipeline connection between smoking tube head and air-introduced machine, air-introduced machine is followed by air preheat
Pipe.
The air inducing pipeline, air-introduced machine, economizer bank, wherein, high-temperature flue gas is extracted via air inducing pipeline by air-introduced machine
Collect, the exhaust gases passes of air inlet economizer bank are preheated to the air in air duct.
Beneficial effect：
(1) flue gas of inflow economizer bank 5 forms adverse current in exhaust gases passes 7 and air duct 6 with combustion air and changed
The part of waste heat of flue gas, is passed to low temperature combustion air, not only having preheated air also makes flue-gas temperature by heat through tube wall again
Further reduction, it is achieved thereby that the abundant recovery to high-temperature flue gas waste heat, improves the thermal efficiency of gas-cooker.
(2) deficiency for the combustion system that gas-cooker is used can be made up by improving the initial temperature of combustion air, while can also
Flue-gas temperature during burning is improved, fuel is effectively saved.

Embodiment
The present invention is the heat-exchanger rig that a kind of gas-cooker high-temperature flue gas is utilized, using by reclaiming the height not being fully utilized
Warm flue gas and the mode preheated to supplement air, to improve the bulk temperature of combustion gas and air mixture, so as to improve heat
Efficiency, saves fuel.The present invention includes following two parts：
1) high-temperature flue gas retracting device
Some appropriately sized holes are opened on the housing nearer apart from fire cover, for installing blower fan and smoking pipeline.Smoking
Pipeline extends out from housing, keeps suitable distance (it is required that neither influenceing the heating to the bottom of a pan, can suck again more with the bottom of a pan
The high temperature cigarette not being fully utilized), pipeline front end is provided with the less guard in aperture, prevents larger particles from being made into pipeline
Into obstruction, tail end is connected with air-introduced machine suction joint.
2) economizer bank is supplemented
Flue gas flows by bushing type pipeline section one section longer, the intermediate conduit good metal material of thermal conductivity simultaneously with air
Expect (present invention uses copper), perisporium is aided with ring rib.Pipe uses resistant to elevated temperatures stainless steel material, while the additional one layer of heat preservation of pipe
