Abstract

The utility model discloses a biomass fuel burning boiler which includes a furnace body, a furnace cavity, a furnace door, a soot door and a smoke exhaust port. Wherein, the upper part of the furnace cavity is provided with a globoid smoke-isolation top, and the lower part of the furnace cavity is provided with an inclination-type mutually-vertical composite-layer water cooling grate. The furnace cavity inner wall in the lower part of the composite-layer water cooling grate is provided with an insulation wall which is provided with a plurality of smoke pipes. One end of the smoke pipe is arranged on the furnace cavity inner wall in the upper part of the smoke-isolation top. The smoke-isolation top and the composite-layer water cooling grate are provided with a spiral material feeding machine, a blower and the furnace door. The furnace cavity in the lower part of the composite-layer water cooling grate is provided with the soot door. The utility model is simple-structured, convenient, environmentally protective and energy-saving. The utility model is a biomass fuel burning boiler of high thermal efficiency, no solid waste and ash fertilizer production.

Description

The firing biomass fuel boiler
Technical field
The utility model belongs to the combustion apparatus technical field, relates in particular to a kind of firing biomass fuel boiler.
Background technology
Biomass fuel is everlasting and is used in the boiler in rural area, have cheap, pollute little, easy to use, with advantages such as back ash can apply fertilizer, but the combustion chamber of present employed plain cylindrical furnace can not the completing combustion biomass fuel, as using, its thermal efficiency is low excessively, and energy waste is serious.
Summary of the invention
The purpose of this utility model is to be to provide a kind of thermal efficiency height, the generation of no solid waste and can to make the firing biomass fuel boiler of ash with fertilizer.
The purpose of this utility model is achieved in that the firing biomass fuel boiler that the utility model provides, comprise body of heater, burner hearth, fire door, ash-digging gate and exhaust opening, wherein, described upper furnace is provided with arc surfaced and pushes up every cigarette, upside is provided with water pipe every the cigarette top, can prevent that every cigarette top hot cigarette from directly discharging from exhaust opening, downside every the cigarette top is provided with the orthogonal multiple layer water-cooled grate of tilting, the orthogonal multiple layer water-cooled grate of tilting can make the fuel of sending here from feed screw evenly cover, its orthogonal multi-layer structure can make the tiny fuel particle that falls from upper fire-grating form second-time burning at lower fire grating, has improved the thermal efficiency, and the inboard wall of furnace body of multiple layer water-cooled grate downside is provided with adiabatic wall, further improved the thermal efficiency, adiabatic wall is provided with several and leads smoke pipe, and the other end of leading smoke pipe is located on the inboard wall of furnace body of cigarette top upside, and the body of heater between Yan Ding and multiple layer water-cooled grate is provided with feed screw and air blast.
Described body of heater between Yan Ding and multiple layer water-cooled grate is provided with fire door, is used to light, puts a chimney on the stove and make the fire draw and observation post's usefulness.
The body of heater of described multiple layer water-cooled grate downside is provided with ash-digging gate.
Be respectively equipped with delivery port and water inlet on described body of heater upside and the downside.
Usefulness of the present utility model is: 1, the orthogonal multiple layer water-cooled grate structure of tilting of the present utility model can make biomass fuel can access stable continuing and burning fully, has improved the thermal efficiency.2, arc surfaced of the present utility model pushes up and leads smoke pipe and can play anti-burning effect every cigarette, has prolonged the time of hot cigarette in stove, has further improved the thermal efficiency.3, be fully burned owing to living beings, the particulate matter of nonpollution environment in the cigarette, and ash can apply fertilizer.4, easy to use, simple in structure.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
In Fig. 1,1, burner hearth, 2, every the cigarette top, 3, a multiple layer water-cooled grate, 4, adiabatic wall, 5, lead smoke pipe, 6, body of heater, 7, feed screw, 8, air blast, 9, fire door, 10, ash-digging gate, 11, delivery port, 12, water inlet, 13, water pipe, 14, exhaust opening.
The specific embodiment
As shown in Figure 1, the firing biomass fuel boiler that the utility model provides, comprise body of heater, burner hearth, fire door, ash-digging gate and exhaust opening, wherein said burner hearth 1 top is provided with arc surfaced every cigarette top 2, push up 2 upsides every cigarette and be provided with water pipe 13, downside every cigarette top 2 is provided with the orthogonal multiple layer water-cooled grate 3 of tilting, these 6 inwalls of stove of orthogonal multiple layer water-cooled grate 3 downsides of tilting are provided with adiabatic wall 4, adiabatic wall 4 is provided with several and leads smoke pipe 5, the other end of leading smoke pipe 5 is located at every cigarette and pushes up on body of heater 6 inwalls of 2 upsides, body of heater 6 between cigarette top 2 and multiple layer water-cooled grate 3 is provided with feed screw 7 and air blast 8, described body of heater 6 between cigarette top 2 and multiple layer water-cooled grate 3 is provided with fire door 9, and the body of heater 6 of described multiple layer water-cooled grate 3 downsides is provided with ash-digging gate 10, is respectively equipped with delivery port 11 and water inlet 12 on described body of heater 6 upsides and the downside.
During concrete the use, earlier delivery port 11, connect unimpeded between water inlet 12 and the body of heater 6, imported water, in burner hearth 1, insert biomass fuel by feed screw 7 then, biomass fuel is put well on the orthogonal multiple layer water-cooled grate 3 of tilting, light by fire door 9, open air blast 8 constantly oxygen supply in burner hearth 1, biomass fuel is during burning on the multiple layer water-cooled grate 3, the tiny fuel particle that falls from the orthogonal upper fire-grating of layer water-cooled grate 3 again of tilting forms second-time burning at lower fire grating, the cigarette of burning imports in cigarette pushes up the body of heater 6 of 2 upsides by leading smoke pipe 5, water pipe 13 and body of heater 6 interior water in the body of heater 6 are warmed, discharge from exhaust opening 14, the ash of after-flame is then fallen furnace bottom, is drawn out by ash-digging gate 10 to get final product again.
