Abstract
The utility model relates to a natural air supplying biomass semi-gasification furnace which comprises a combustion chamber, a fire gathering opening, a cooking opening, a fire grate and a dust accumulation chamber, wherein a semi-gasification combustor is arranged above the fire gathering opening, and the cooking opening is formed in the upper end of the semi-gasification combustor; a secondary air disc containing an annular cavity is additionally installed on the fire gathering opening, and air exhaust small holes are arranged in the annular inner ring surface of the secondary air disc; 2-4 air pipes are arranged in a furnace body, one end of each air pipe is communicated to the external of the furnace, and the other end of each air pipe is communicated with the annular cavity of the secondary air disc. According to the natural air supplying biomass semi-gasification furnace, air supplementation is automatically achieved by means of a pressure difference produced by cold and hot air, an air blower is needless to be used, and the furnace is simple in structure, convenient to use and high in heat efficiency.
Description
Technical field
The utility model relates to a kind of civilian biomass stove, the natural air feed biomass half-gasification oven that particularly to use living beings be fuel.
Background technology
With crops stem, branch, leaf, stalk the like waste, as fuel, be called biomass fuel.The old-fashioned kitchen range that rural area is traditional and the current commercially available most combustion efficiency of civilian living beings kitchen range are poor, and the combustion-supporting ability of large pogoniasis configuration air blast is normally used, and has increased acquisition cost, and connects electricity trouble, has increased unsafe factor in use.
Summary of the invention
The purpose of this utility model is a kind of gravity-flow ventilation half-gasification oven of design, and it,, without configuration air blast, utilizes natural wind can reach good air feed combustion-supporting effect.
The utility model nature air feed biomass half-gasification oven, comprises body of heater, combustion chamber, poly-burner, cooking mouth, fire grate and dust stratification thorax, and described poly-burner top is provided with half gasification combustion chamber, and cooking mouth is located at the upper end of half gasification combustion chamber; On poly-burner, install the Secondary Air dish that includes toroidal cavity additional, the annular inner ring face of Secondary Air dish is arranged with air-out aperture; Described body of heater is provided with 2-4 root airduct, and outside the logical stove in one end of each airduct, the other end communicates with the toroidal cavity of Secondary Air dish.
The bottom-up flame retardant coating through combustion chamber periphery of described each airduct, upper end all communicates with the toroidal cavity of Secondary Air dish, and each airduct is equidistantly to distribute.
The lower port of described airduct is respectively equipped with adjusts windscreen sheet.
Described airduct number is advisable with 3.
Described half gasification combustion chamber is connected with smoke hatch.
In this stove and accessory, fire grate, for once ventilating, is provided with the secondary air feed system being connected with many airducts by Secondary Air dish simultaneously, utilize body of heater upper and lower between the pressure differential of cold and hot γ-ray emission can automatically realize wind-force and supplement, the large I of firepower is by adjusting windscreen sheet to regulate.This stove be take biomass material as fuel, sufficient combustion, strong without black smoke, firepower, and without the air blast of the machine of use, simple in structure, easy to use, the thermal efficiency is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of this stove and accessory.
Fig. 2 is the A-A cutaway view of Fig. 1.
In figure, 1-smoke hatch, 2 —Ban gasification combustion chamber, 3-cooking mouth, 4-air-out aperture, 5-Secondary Air dish, 6-body of heater, 7-fire grate handle, 8-movable furnace grate, 9-dust stratification thorax, 10-ash pinch, 11-stove pin, 12-tune windscreen sheet, 13-flame retardant coating, 14-airduct, 15-combustion chamber, 16-poly-burner.
The specific embodiment
Below in conjunction with accompanying drawing, further illustrate structure and the operation principle of the utility model nature air feed biomass half-gasification oven.
The structure of nature air feed biomass half-gasification oven is as Fig. 1 and Fig. 2, and poly-burner 16 tops are provided with half gasification combustion chamber 2, and cooking mouth 3 is located at the upper end of half gasification combustion chamber; Secondary Air dish 5 containing toroidal cavity is placed on poly-burner 16, and its annular inner ring face is arranged with air-out aperture 4; Three airducts 14 equidistantly distribute, the bottom-up flame retardant coating 13 through combustion chamber 15 peripheries of difference, and upper end all communicates with the toroidal cavity of Secondary Air dish 5, and lower end is led to outside stove, and the lower port of each airduct 14 is respectively equipped with adjusts windscreen sheet 12.
During the work of this combustion furnace, first will in combustion chamber 15, fill it up with biomass fuel to the height that approaches Secondary Air dish 5, then from poly-burner 16, light biomass fuel.The tune windscreen sheet 12 of three ventilating duct 14 bottom outlets is opened greatly, and body of heater 6 extraneous air Fen San roads pass in Secondary Air dish 5, by the one week exhaust vent 4 on Secondary Air dish 5, are flowed out, and double gasification combustion chamber is combustion-supporting.After flare burning is more stable, can carry out cooking work, according to the needs to stove fire intensity in cooking, can regulate at any time windscreen sheet 12, the size that changes Secondary Air is controlled firepower.The hot flue gas producing can be warmed oneself by the logical a heatable brick bed of smoke hatch 1.After fuel combustion, its ashes fall to dust stratification thorax 9 by shake fire grate handle 7 by movable furnace grate 8 gaps, use ash pinch 10 deashings.
Claims (5)
1. natural air feed biomass half-gasification oven, comprises body of heater, combustion chamber, poly-burner, cooking mouth, fire grate and dust stratification thorax, it is characterized in that described poly-burner top is provided with half gasification combustion chamber, and cooking mouth is located at the upper end of half gasification combustion chamber; On poly-burner, install the Secondary Air dish that includes toroidal cavity additional, the annular inner ring face of Secondary Air dish is arranged with air-out aperture; Described body of heater is provided with 2-4 root airduct, and outside the logical stove in one end of each airduct, the other end communicates with the toroidal cavity of Secondary Air dish.
