Detailed description of the invention
The technological means realized to make the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment being clearly and completely described.
Referring to Fig. 1-5, this detailed description of the invention is achieved by the following technical solutions, it comprises high pressure positive blower 1, the air-flow output of this high pressure positive blower 1 is connected with diversion three-way 4 through volume control damper 2 by main air supply duct 3, the other two ends of described diversion three-way 4 are connected with right flank blast main road 6 with left surface blast main road 5 arranged in parallel respectively, described left surface blast main road 5 is installed with left surface air-supply arrangement, described right flank blast main road 6 is installed with the right flank air-supply arrangement relative with left surface air-supply arrangement, described left surface air-supply arrangement comprises the left surface air-supply standpipe 7 be intermittently arranged on left surface blast main road 5, the side of this left surface air-supply standpipe 7 is vertically installed with the left surface blowpipe 9 relative with right side air-supply arrangement, described right flank air-supply arrangement comprises the right flank air-supply standpipe 8 be intermittently arranged on right flank blast main road 6, the side of this right flank air-supply standpipe 8 is vertically installed with the right flank blowpipe 10 relative with left side air-supply arrangement.
The quantity of each row left surface blowpipe 9 in the air-supply arrangement of described left side is arranged on each left surface air-supply standpipe 7 according to certain axial order.
The quantity of each row right flank blowpipe 10 in the air-supply arrangement of described right side is arranged on each right flank air-supply standpipe 8 according to certain axial order.
In the present embodiment, left and right air outlet inwardly increases gradually along burner hearth, and air output continues to increase, and forms gradual change and expands air supply stream.
The course of work: after boiler startup, start high pressure positive blower 1, regulated the size of air quantity by volume control damper 2, Secondary Air, respectively by respective left surface blowpipe 9 and right flank blowpipe 10, is sent into burner hearth by left surface blast main road 5 and right flank blast main road 6; Because left surface air-supply arrangement and right flank air-supply arrangement are oppositely arranged each other, the air sent into inwardly is increased along burner hearth gradually by left and right air outlet, air output continues to increase, form gradual change and expand air supply stream, produce flaring crosswind in opposite directions in combustion to biomass fuel, be conducive to the burning completely of biomass fuel, tar cannot deposit at fire grate simultaneously, and be in suspended state, and be repeatedly mixed to get to burn with biomass fuel.In combustion process, fire grate is pusher, and biomass fuel is in suspended state, cannot slagging scorification on fire grate, and lime-ash is pushed to ashcan by fire grate running, gets rid of outward transport by spiral-type slag eliminator.
Last it is noted that above embodiment is only in order to illustrate the technical solution of the utility model, be not intended to limit; Although be described in detail the utility model with reference to previous embodiment, those of ordinary skill in the art is to be understood that, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature; And these amendments or replacement, do not make the essence of appropriate technical solution depart from the spirit and scope of each embodiment technical scheme of the utility model.
