Abstract

The utility model discloses a biomass combustor, relating to combustion equipment and aims at providing a biomass combustor capable of leading flammable biomass briquette to be burned continuously. The technical scheme is as follows: the biomass combustor comprises a vaporizing chamber, a mixed combustion chamber, a feeder and a slag remover, wherein a distributing device is arranged below the feed port of the vaporizing chamber; the lower part of the vaporizing chamber is communicated with the mixed combustion chamber; a chain-type fire grate is arranged below and communicated with the vaporizing chamber and the mixed combustion chamber; a reduction box is respectively connected with a motor and the main shaft of the chain-type fire grate; the chain wheel on the main shaft of the distributing device is opposite to the chain wheel on the main shaft of the chain-type fire grate; and two side walls of the vaporizing chamber and the mixed combustion chamber are provided with air distribution outlets which are communicated with the air outlet pipe of a fan. The utility model is used for biomass combustors.

Description

A kind of biomass burner

Technical field:

The utility model relates to a kind of combustion apparatus, particularly a kind of biomass burner.

Background technology:

The structure of existing biomass burner is that vaporizer is established on top, and the bottom is a hybrid combustor, and fire grate is fixed, this structure is for various farming stalks, the shaped fuel that is pressed into of maize straw particularly, the very fast slagging scorification because burning time is short, burner can't normally use when serious.

Summary of the invention:

The purpose of this utility model provides a kind of biomass burner that makes inflammable biomass block continuous burning.The technical solution of the utility model is, comprise vaporizer, hybrid combustor, feeder and slag remover, it is characterized in that: below the charging aperture of vaporizer, be provided with distributing device, the bottom of vaporizer is communicated with hybrid combustor, chain furnace grate places the below of vaporizer and hybrid combustor to be communicated with above-mentioned vaporizer and mixing chamber, reductor is connected with the chain furnace grate main shaft with motor respectively, sprocket wheel on the distributing device main shaft is relative with sprocket wheel on the chain furnace grate main shaft, is provided with air distribution outlet and is communicated with the discharge pipe of blower fan on the two side of vaporizer and hybrid combustor.The utility model has the remarkable advantage of the fast continuous normal combustion of biomass block of easy firing slagging scorification compared with the prior art.

Description of drawings:

Fig. 1 is a structural representation of the present utility model, and Fig. 2 is the A-A profile of Fig. 1, and Fig. 3 is the vertical view of Fig. 1, and Fig. 4 is the B-B profile of Fig. 3.

The specific embodiment:

In conjunction with above accompanying drawing the utility model is described in detail, front end at burner shell 1 internal upper part is a vaporizer 12, the charging aperture 10 on this vaporizer top is relative with the discharging opening of feeder, the rear side of vaporizer bottom is communicated with hybrid combustor 11, the secondary air distribution outlet 2 that the sidewall of vaporizer is provided with on air distribution outlet 3 and the hybrid combustor sidewall is communicated with the discharge pipe of blower fan respectively, chain furnace grate 14 places the below of vaporizer and hybrid combustor, reductor 5 is connected with chain furnace grate main shaft 13 with motor 4 respectively, mucking machine 7 is communicated with the lime-ash chamber of chain furnace grate below, and the lime-ash cavity is provided with ashpit 6.The below of vaporizer charging aperture is provided with distributing device, and the sprocket wheel on the distributing device main shaft is relative with sprocket wheel on the chain furnace grate main shaft.The right-hand member of hybrid combustor is provided with fire output hole 15 and is communicated with boiler.On the front side wall of vaporizer, be provided with igniting fire door 8, have flame-observing hole 9 on the igniting fire door.

Operation principle of the present utility model is, biomass block fuel is sent into vaporizer by feeder (can be the screw feeder feeder), when the fuel of vaporizer reach a certain height, the blade of distributing device unplugs fuel to both sides, fuel evenly is placed on the fire grate, guarantees that fuel can evenly gasify and smooth combustion.After even on the fuel, open igniting fire door 8, get light a fire in an amount of flammable materials load point stove door after, open boiler induced-draft fan, close the igniting fire door after three minutes, starting chain furnace grate rotates, open air blast, adjust the air quantity of each air distribution, make burning be in optimum state, adjust the fire grate speed of mainshaft simultaneously, make fuel arrive the preceding after-flame fully of fire grate end, adjust the material loading speed of feeder then, make material loading speed identical with the fire grate translational speed, keep the fuel height in the vaporizer to be consistent, realize the gasification of fuel and the stable operation of burning.When needing blowing out, stop material loading earlier, after the fuel in vaporizer is gasified totally, stop air blast and air-introduced machine again, boiler is out of service.

Claims
