Described the first flue and described the second flue all communicate with the outlet of blower mill, described the first flue stretches into described burner hearth and communicates with described the first auxillary flue, the two-port of described the first auxillary flue is respectively equipped with described nozzle, described the second flue stretches into described burner hearth and communicates with described the second auxillary flue, the two-port of described the second auxillary flue is respectively equipped with described nozzle, and two described nozzles of described the first auxillary flue two-port are relative with described two nozzle locations of described the second auxillary flue two-port;
Described in each, on nozzle, be equipped with described burner;
Described burner hearth inside is provided with smoke-returning pipeline, and described smoke-returning pipeline communicates with described the first flue and described the second flue, is connected with back cigarette blower fan on described smoke-returning pipeline.
The utility model can also adopt following technical measures:
The position of two described nozzles of described the first auxillary flue two-port and described two nozzles of described the second auxillary flue two-port forms square.
Two described nozzles of described the first auxillary flue two-port and the angle of horizontal direction are 35 ° and its towards relative, and described two nozzles and the angle of horizontal direction of described the second auxillary flue two-port is 35 ° and it is towards relative.
Advantage and the good effect that the utlity model has are: technique scheme is when effectively improving boiler combustion efficiency, reasonably reuse the sufficient high-temperature flue gas of unburned in burner hearth, heat of high temperature and the sufficient coal charge of unburned have all been done to the good result that effective secondary utilization has reached energy-saving and emission-reduction.
