Degree is increased to designated value, can partial fume that smoke outlet leaves and low temperature be helped combustion gas mixing at this time, improved combustion-supporting
The temperature of gas.
Since the combustion-supporting component contents such as oxygen in flue gas are less, so preferentially selecting the heat that will not be utilized at heat outlet
Gas returns to furnace chamber and is continuing with, and when hot gas is it is impossible to meet needing, can just reuse flue gas.
Preferably, being enclosed with more than two gas circulation layers, the gas on the outside of the furnace chamber successively from inside to outside
The layer that circulates includes exhaust gases passes and pre- hot gas path, and the exhaust gases passes are connected to exhanst gas outlet, and preheater channel enters with cold air
Mouth connection.
As much as possible to improve the utilization rate of flue gas, using remaining flue gas after heat exchange to the gas in heat exchanger
It is preheated.Exhaust gases passes and preheater channel are equivalent to cover and impinge upon on furnace chamber, and contact area is big, and heat exchange efficiency is high.
Preferably, the exhaust gases passes and pre- hot gas path at least one there are two more than, and exhaust gases passes and
Pre- hot gas channel spacing setting, is interconnected between two neighboring exhaust gases passes or pre- hot gas path.
Theoretically, the time that flue gas and cold air flow in exhaust gases passes and preheater channel is longer, and heat exchange efficiency is got over
Height, but the cost of equipment can also increase, it is possible to as needed, select the quantity of exhaust gases passes and pre- hot gas path.
Preferably, the pre- hot gas path there are two more than, leads between two gases circulation layer of furnace chamber
Cross the heat exchanger connection.
Cold air preheating after enter heat exchanger in, carry out heat exchange after from most close to the gas of furnace chamber circulation layer in from
It opens, can further heat at this time.
Compared with prior art, the beneficial effects of the utility model are at least one of following：
Unique burner structure is conducive to being sufficiently mixed for oil gas and fuel gas, keeps burning more abundant.
Hot gas or flue gas are returned into burner hearth and re-use preheating therein, improves the efficiency of combustion of fuel.
