Abstract
The utility model relates to the field of boiler technology a biomass fuel boiler, form by boiler body, furnace arch, automatic burner, ash hole, feed bin, auger, fuel injection machine, grate, two substandard cloth tuber pipes, combustion chamber furnace arch, arch wall, flue, draught fan and dust collector. Many return strokes auger with fuel powder pure, refine, by fuel injection machine direct spirt combustion chamber lower part once burning, two substandard cloth tuber pipes make once burning not have fuel suspension carrying on on the combustion chamber upper portion postcombustion of after -flame, flame, flue gas that the burning produced pass arch wall down in the draught fan effect and get into the flue gas room, move towardss to get into the flue along the S type that is separated by the furnace arch, pass through the emission of chimney high altitude behind draught fan and dust collector. The beneficial effects are that: can solve material loading homogeneity and boiler and give wind rationality problem, it is fully efficient to burn, and soot emissions is pollution -free, applicable in various biomass fuel.

China is a large agricultural country, and living beings kind is many, enormous amount, efficiently, reasonably utilizes the abandoned biomass such as wood shavings, sawdust, straw, rice husk, stalk to substitute the fossil fuels such as coal-fired, not only energy-conservation but also environmental protection.At present, existing biomass fuel boiler generally adopts artificial loading or traveling-grate stoker feed, two kinds of feeding methods all do not solve being uniformly distributed with boiler to the reasonability problem of wind of material loading very well, also exist burning insufficient, efficiency is not high, soot emissions are difficult to the defects such as up to standard, some boilers also also exist biomass fuel Single-issue.
Summary of the invention
For overcoming prior art defect, the technical problem that the utility model solves is to provide a kind of biomass fuel boiler, adopt the feeding of many backhauls cage, fuel spraying machine and repeatedly to technology such as wind, solve material loading uniformity and boiler to wind reasonability problem, the abundant efficiency of fuel combustion is high, and soot emissions are pollution-free.
In order to achieve the above object, the utility model realizes by the following technical solutions:
A kind of biomass fuel boiler, comprise boiler body, chimney arch, automatic burning device, ash hole, feed bin, auger, fuel spraying machine, fire grate, secondary wind distribution pipe, combustion chamber chimney arch, arch wall, flue, air-introduced machine and dust arrester, it is characterized in that, in described boiler body, front portion, lower-left is provided with automatic burning device, rear portion, lower-left is provided with ash hole, and top is provided with secondary wind distribution pipe; Boiler intracavity is divided into combustion chamber and smoke chamber by described arch wall, and combustion chamber is divided into upper and lower two parts by combustion chamber chimney arch, and fire grate is arranged on bottom, combustion chamber, automatic burning device top; Being provided with many backhauls auger in described feed bin, chats in one end of auger and fuel spraying machine, the other end access bottom, boiler body combustion chamber of fuel spraying machine; Described chimney arch is three pieces, and one end that top is two pieces is connected with boiler body top, and the other end is unsettled, and one end of following one piece is connected with boiler body bottom, and the other end is unsettled; One end of described flue is communicated with boiler body, and the other end is connected with air-introduced machine and dust arrester.
Described chimney arch is ground one's teeth and is provided with N number of ventilating opening.
Described combustion chamber chimney arch is provided with N number of ventilating opening.
Described arch wall is provided with some flame and exhaust gases passes.
Compared with prior art, the beneficial effects of the utility model are: adopt the feeding of many backhauls cage, fuel spraying machine and repeatedly to technology such as wind, solve material loading uniformity and boiler to wind reasonability problem, the abundant efficiency of fuel combustion is high, soot emissions are pollution-free, are applicable to various biomass fuel.
