To achieve the goals above, the utility model adopts the following technical solution: a kind of coke oven flue is interior to heat flue gas liter
Warm device, including coke oven flue gas burner, the coke oven flue gas burner include horizontal firing room, gas pipe, igniting fuel gas conduit
And burning torch, the horizontal firing room are mounted in the horizontal segment of flue, the left end of the horizontal firing room is equipped with burning
Head, the combustion head stretches out outside flue to be connected to one end of gas pipe, the other end of the gas pipe and the igniting fuel gas conduit
One end connection, the other end of the igniting fuel gas conduit is arranged in the combustion head to be connect with burning torch.
Preferably, valve group, the valve group connection control are additionally provided with close to one end of igniting fuel gas conduit on the gas pipe
System, control system can control burning torch igniting, fire extinguishing according to flue-gas temperature, have defencive function.
Preferably, the outside of the outer wall of the horizontal firing room and horizontal firing room left end is poured fire proofed wood
Material, refractory material not only protect horizontal firing room, also act as heat-blocking action.
Preferably, the combustion head has combustion aid function far from combustion fan is equipped with below the one end of horizontal firing room.
Preferably, flue-gas temperature alarm device is installed, flue-gas temperature is lower than setting value, alarm, so on the combustion head
Firing up is carried out to flue gas afterwards.
Compared with prior art, coke oven cigarette is arranged in the utility model between coke oven flue gas delivery pipe and SCR denitration device
Air burner can effectively promote coke oven flue gas to medium temperature or high temperature from low temperature, improve coke oven flue gas and fill in SCR denitration
Denitration efficiency in setting also improves the service life of denitrating catalyst and using activity, reduces sold out operation expense, and denitration
System operation is relatively reliable and stablizes.
Detailed description of the invention
