Description

A kind of big burner hearth biomass burner
Technical field
The utility model relates to a kind of big burner hearth biomass burner.
Background technology
At present, the stockhole of biomass stove all is cone shape, and secondary air hole is distributed on the conical surface, and for the small oven of firing biomass fuel, this layout structure is simple and reliable, sufficient combustion.But, when burner hearth during greater than certain size, the macro-organism matter cooking stove in dining room particularly, the secondary wind on the conical surface can't add to the cores of fire door, thereby causes biomass fuel combustion very insufficient, a large amount of black smokes of emerging.
In sum, to the defective of prior art, need a kind of big burner hearth biomass burner especially, with the problem of mentioning more than solving.
The utility model content
The purpose of the utility model is to provide a kind of big burner hearth biomass burner; Through changing the shape of stockhole, improve the temperature of secondary wind, and with the high temperature secondary wind stockhole center of extending; Biomass fuel is fully burned in stove, reaches effect energy-conservation, efficient low-discharging.
The technical problem that the utility model solved can adopt following technical scheme to realize:
A kind of big burner hearth biomass burner comprises a cylinder-shaped body, and the set inside of main body is a burner hearth, and external side of main body is provided with charge door, and the bottom of main body is provided with air inlet; The bottom of said burner hearth is provided with grate, and air inlet and burner hearth are communicated in the bottom of main body, and charge door and burner hearth are communicated in a side of main body; It is characterized in that; The inside of main body also is equipped with the secondary air feed system of being made up of secondary air channel, annular passage, fire door heat-insulation layer and the eye of wind, and said fire door heat-insulation layer is arranged at the top of main body, and annular passage is close to the below of fire door heat-insulation layer; The bottom of annular passage is communicated with some secondary air channels; The other end of secondary air channel is set to two air inlets, and the centre of said fire door heat-insulation layer is a stockhole, and the arranged outside of annular passage has some eyes of wind.
In an embodiment of the utility model, said charge door comprises passage and sliding door.
In an embodiment of the utility model, said stockhole adopts the decussate texture design.
The beneficial effect of the utility model is: the burning in the burner hearth is more abundant, has realized the requirement of energy-saving and environmental protection, efficient, low emission.
Description of drawings
Fig. 1 is the structural representation of the described big burner hearth biomass burner of the utility model.
Fig. 2 is the vertical view of the described big burner hearth biomass burner of the utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and be easy to understand understanding with effect, below in conjunction with the specific embodiment, further set forth the utility model.
As depicted in figs. 1 and 2, the described a kind of big burner hearth biomass burner of the utility model comprises a cylinder-shaped body, and the set inside of main body is a burner hearth 5, and external side of main body is provided with charge door 9, and the bottom of main body is provided with air inlet 10; The bottom of said burner hearth 5 is provided with grate 8, and air inlet 10 and burner hearth 5 are communicated in the bottom of main body, and charge door 9 and burner hearth 5 are communicated in a side of main body.
The inside of main body also is equipped with the secondary air feed system of being made up of secondary air channel 6, annular passage 4, fire door heat-insulation layer 3 and the eye of wind 2; Said fire door heat-insulation layer 3 is arranged at the top of main body; Annular passage 4 is close to the below of fire door heat-insulation layer 3, and the bottom of annular passage 4 is communicated with some secondary air channels, and the other end of secondary air channel is set to two air inlets 9; The centre of said fire door heat-insulation layer 3 is the stockhole 1 of decussate texture, and the arranged outside of annular passage 4 has some eyes of wind 2.
The workflow of the utility model is following:
The secondary air feed system of being made up of secondary air channel 6, annular passage 4, the eye of wind 2, fire door heat-insulation layer 3 places in the burner hearth 5; Biomass fuel gets into burner hearth 5 from charge door 9; Light biomass fuel, close charge door 9, open air inlet 10 one time; A wind got in the burner hearth 5 through grate 8 and was the oxygen supply of burning the first time of biomass fuel this moment; Because secondary air channel 6, annular passage 4 has absorbed a large amount of heat in burner hearth 5 during burning, and secondary wind is through secondary air mouth 7, secondary air channel 6, annular passage 4, become high-temperature hot-air by cold wind when the eye of wind 2 comes out.When furnace flame rushes at cross stockhole 1, just with the secondary high-temperature hot-air that is uniformly distributed with along cross stockhole 1 periphery fully burning takes place for the second time.Again because stockhole be cross, under the prerequisite that does not reduce the due area of passage of stockhole, stockhole is crossed flow diameter 11 and can be reduced greatly, like this flame of stockhole center also just can with the abundant mixed combustion of secondary high-temperature hot-air.
The beneficial effect of the utility model is: the burning in the burner hearth is more abundant, has realized the requirement of energy-saving and environmental protection, efficient, low emission.
More than show and described basic principle of the utility model and the advantage of principal character and the utility model.The technical staff of the industry should understand; The utility model is not restricted to the described embodiments; The principle of describing in the foregoing description and the specification that the utility model just is described; Under the prerequisite that does not break away from the utility model spirit and scope, the utility model also has various changes and modifications, and these variations and improvement all fall in the utility model scope that requires protection.The utility model requires protection domain to be defined by appending claims and equivalent thereof.
