Specific embodiment
Embodiment 1
Modified flue gas reuse heat-accumulating burner, including L-type shell 1, air/smoke channel 2, blast tube 3 and igniting
Rifle 4 is equipped with honeycomb heat accumulation body 5 in air/smoke channel, and interval opens up maintenance door 1 and maintenance on the adjacent side body of heat storage
Door 2 52, facilitates the replacement of heat storage, and top is equipped with air/smoke connector 6,3 one end of blast tube and air/smoke channel 2
Vertical connection, the other end are equipped with the nozzle 7 of tubaeform gradually wide structure, and natural gas tube 8 is coaxially provided in blast tube 3, and combustion gas is logical
The junction in road 3 and air/smoke channel 2 is equipped with the air cyclone 31 and flue gas cyclone of whirl hole distribution annular in shape

32。
Burning torch 4 is mounted on shell 1 and extends at nozzle 7, and burning torch is equipped with ignition controller, for examining
Survey flame combustion state and control burning torch igniting, it is ensured that safe combustion.
The burning of heat-accumulating burner is arranged:
As shown in figure 3, two modified flue gas reuse heat-accumulating burners in mirror image distribution are one group, type cigarette is often only improved
The air/smoke interface of gas reuse heat-accumulating burner installs a set of three-way diverter valve, for the conversion of air and flue gas, reflux
Flue entrance installs a set of control valve, and for the open and close of backflow flue gas, gas inlet installation is a set of natural
Gas control valve, the open and close for natural gas.
When in actual work, the air valve of a modified flue gas reuse Pulverizing Jet Three-way Diverter Valve Of Heat Accumulating Type opened, flue gas
Valve is closed, and backflow flue gas valve is opened, natural air valve is opened, and the smoke valve of another modified flue gas reuse heat-accumulating burner is beaten
It opens, air valve is closed, backflow flue gas valve is closed, natural air valve is closed, two modified flue gas reuse heat accumulating types burnings after commutation

The smoke outlet of every modified flue gas reuse heat-accumulating burner all installs the cigarette of a thermocouple detection discharge
Temperature degree, commutating period are set in conversion in 60 seconds once, and flue-gas temperature is controlled at≤120 DEG C.When flue-gas temperature is more than 120 DEG C
When, control program carries out forced commutation.Operation work in cycles is carried out under the instruction of control program.Ensure to reduce heat
Discharge, it is energy saving, reduce energy consumption.
Burning working method:
Air enters modified flue gas reuse heat-accumulating burner, flows through after heat storage and backflow flue gas infiltration enters burner,
It is mixed again with natural gas, at this time when this TV station burner flame release heat, another modified flue gas reuse heat-accumulating burner sucking
The flue gas that this TV station burner generates carries out smoke evacuation and heats heat accumulation to the heat storage in this burner.After commutation, the function of two burners
It can convert mutually, the burner originally discharged fume is converted to flame release heat, and the burner of flame burning is converted to smoke evacuation, and heat storage adds
Hot heat accumulation.
Heat in heat storage is stored in during this to heat the cold air of entrance, and with the flue gas, the natural gas that back into
It is mixed and sprays into furnace, so that the uniformity of furnace temp is reached optimum efficiency by the combustion system of this drawing and pulling type, have
It is heated evenly conducive to workpiece, reduces the consumption of natural gas, save fuel.
When flue-gas temperature is in 1200 DEG C of discharges, air preheating temperature can theoretically can reach to 1000 DEG C or more, can make
The heat consumption of stove will be substantially reduced than general heating furnace, to save fuel 40% or so.
