As a kind of prioritization scheme, the body of heater of described burner hearth position is provided with cavity and air admission hole.
A kind of concrete prioritization scheme, an end of described air admission hole is communicated with cavity, and the other end of described air admission hole is communicated with burner hearth.
A kind of concrete prioritization scheme, described air admission hole is along the peripheral, oblique setting.
A kind of concrete prioritization scheme, the quantity of described air admission hole are several, and several air admission holes are along circumferentially uniform.
A kind of concrete prioritization scheme, described cavity is communicated with pipeline between outlet side and the burner hearth.
As a kind of prioritization scheme, described inlet end is provided with air blast, and described air blast is connected with inlet end by pipeline.
As a kind of prioritization scheme, described heat-exchanger rig comprises housing, and the two ends of described housing are respectively arranged with the sealing gripper shoe, is provided with some heat exchanger tubes between two sealing gripper shoes, and the place, centre position of described housing is provided with dividing plate.
The utility model is taked above technical scheme, have the following advantages: because pipe is provided with heat-exchanger rig, heat-exchanger rig is provided with inlet end and outlet side, so, when flue gas process heat-exchanger rig, can heat by the interior air of heat exchanging device, the air of process heating is in piping is transported to burner hearth, in the time of in air enters burner hearth, can not reduce the temperature in the burner hearth, and increase the content of the oxygen in the burner hearth, thereby fuel is burnt fully, reduce the consumption of fuel, the heat that fuel combustion produces is fully utilized, and has improved the thermal efficiency of boiler, behind the full combustion of fuel, content of harmful gas reduces greatly in the flue gas of discharging, thereby has reduced the pollution to environment.
The utility model is described in further detail below in conjunction with drawings and Examples.
