Description
Technical field
The utility model relates to a kind of coal-burning boiler, especially relates to a kind of counter-burning type normal pressure coal burning water heating gas boiler.
Background technology
Large-scale coal gasification boiler of the prior art all is direct-fired; The flue gas that produces promptly enters atmosphere without overcharging divided combustion; While is with a large amount of dust and do not have clean-burning particle to enter atmosphere, and promptly contaminated environment has been wasted resource again, and the chimney easy blocking; The coal gas that produces in the combustion process is not utilized, and the thermal efficiency is low.
The utility model content
The utility model technical problem to be solved is: a kind of counter-burning type coal gasification boiler is provided, and this boiler can make the coal gas, dust and the particle that produce in the combustion process through second-time burning, improves the thermal efficiency, reduces environmental pollution, and chimney is difficult for blocked.
For solving the problems of the technologies described above; The utility model adopts following technical scheme: counter-burning type normal pressure coal burning water heating gas boiler; Comprise: boiler body, said boiler body are provided with burner hearth, heat exchange hydroecium and are enclosed in the water jacket of said burner hearth, and said water jacket is connected with said heat exchange hydroecium; Be provided with the boiler fire tube in the said heat exchange hydroecium; Be provided with the heat exchange fire grate that is communicated with said heat exchange hydroecium and water jacket in the said burner hearth, the zone that in said burner hearth, is positioned at below the said heat exchange fire grate is the combustion chamber, and the burner that advances of said boiler fire tube communicates with said combustion chamber; The crater of said boiler fire tube communicates with air-introduced machine; The zone that in said burner hearth, is positioned at above the said heat exchange fire grate is provided with the coal gas apotheca, and said coal gas apotheca is being provided with coal feeding hole near said heat exchange fire grate place, and the chimney of said boiler is connected with said coal gas apotheca.
Preferably, said boiler fire tube has two backhauls at least.
After having adopted technique scheme; The beneficial effect of the utility model is: because the zone that in said burner hearth, is positioned at above the said heat exchange fire grate is provided with the coal gas apotheca, said coal gas apotheca is being provided with coal feeding hole near said heat exchange fire grate place, and the chimney of said boiler is connected with said coal gas apotheca; So coal gas, dust and particle are through second-time burning; Improved the thermal efficiency, reduced environmental pollution, chimney is not blocked.
Because said boiler fire tube has two backhauls at least,, thereby improve the thermal efficiency so the heat exchange of flue gas is more abundant.
Description of drawings
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is done further detailed explanation:
Fig. 1 is the internal structure sketch map of the utility model;
Wherein, 1 boiler body; 2 burner hearths; 3 heat exchange hydroeciums; 4 water jackets; 5 boiler fire tubes; 6 advance burner; 7 combustion chambers; 8 craters; 9 air-introduced machines; 10 heat exchange fire grates; 11 coal gas apothecas; 12 coal feeding holes; 13 chimneys.
The specific embodiment
As shown in Figure 1, counter-burning type normal pressure coal burning water heating gas boiler comprises: boiler body 1; Said boiler body 1 is provided with burner hearth 2, heat exchange hydroecium 3 and is enclosed in the water jacket 4 of said burner hearth; Said water jacket 4 is connected with said heat exchange hydroecium 3, is provided with boiler fire tube 5 in the said heat exchange hydroecium 3, is provided with the heat exchange fire grate 10 that is communicated with said heat exchange hydroecium 3 and water jacket 4 in the said burner hearth 2; The zone that in said burner hearth 2, is positioned at below the said heat exchange fire grate 10 is combustion chamber 7; The burner 6 that advances of said boiler fire tube 5 communicates with said combustion chamber 7, and the crater 8 of said boiler fire tube 5 communicates with air-introduced machine 9, and the zone that in said burner hearth 2, is positioned at above the said heat exchange fire grate 10 is provided with coal gas apotheca 11; Said coal gas apotheca 11 is being provided with coal feeding hole 12 near said heat exchange fire grate 10 places; The chimney 13 of said boiler is connected with said coal gas apotheca 11, and said boiler fire tube 5 has two backhauls at least, and the backhaul heat exchange of thickness gas more is abundant more.
When coal is filled it up with burner hearth 2, close coal feeding hole 12, coal becomes lime-ash through burning; Simultaneously not clean-burning part produces coal gas and used heat, and coal gas and used heat are stored in coal gas apotheca 11 under a wind action, when air-introduced machine 9 work; Coal gas and used heat get into combustion chamber 7 under the secondary wind action, carry out secondary and fully burn, and accomplish after the heat exchange; The waste gas that produces gets into chimney 13 after carrying out dedusting through dust arrester under the effect of air-introduced machine 9; Thereby improved the thermal efficiency, reduced environmental pollution, reached energy-efficient and purpose environmental protection.
The utility model is not limited to above-mentioned concrete embodiment, and those of ordinary skill in the art is from above-mentioned design, and without performing creative labour, all conversion of having done all drop within protection scope of the present invention.
