Description
Technical field
The utility model belongs to biomass gasification equipment, and biological fuel gas and natural gas are used more particularly to boiler body
The device of burning.
Background technology
The burner of the gas outlet of biomass gasifying furnace at present can only fire caused by single biomass burning gasification
Gas, and primary, the secondary air distribution being incorporated still can not ensure that biological fuel gas burns cinder completely, it is flammable containing not burning down in flue gas
Property gas probability increase, greatly reduce biomass gasification fired thermal energy conversion efficiency.When encountering biomass fuel feelings in short supply
Under condition, other fuel can not be used to carry out quick replacement, be switched fast burning, will appear caused because of fuel supply problem in this way
Halt production phenomenon occurs for thermal break.
Utility model content
For the utility model in order to solve the above problem, the utility model provides a kind of adapted biomass combustion gas and natural gas
Dual-purpose switching burning is to ensure to continue the burner for thermal energy.
In order to achieve the goal above, the technical scheme adopted by the utility model is that being implemented：A kind of biological fuel gas
With natural gas dual burner, including biomass fuel gas port, biomass fuel gas port is passed through biological fuel gas and First air, the life
Guide shell is arranged in the inside of substance combustible gas mouth, and primary combustion air distribution combustion is generated in guide shell, is set on the outside of biomass fuel gas port
Set secondary air chamber, the outside of the secondary air chamber is set with conical furnace mouth, taper fire door setting natural gas channel, outside guide shell
The space formed between side and taper fire door inside is connected to secondary air chamber, and tertiary-air pipe is connected in natural gas channel.
Further, several eddy flow slots of the madial wall setting spiral configuration of the guide shell.
Air distribution diffusion disc is arranged in the exit of the secondary air chamber.
Gas diffusion disk is arranged in the exit in the natural gas channel.
Implement technical solutions of the utility model, for the combustion gas that is generated after gasification of biomass carry out it is primary, secondary, divide three times
Level air-distribution burns, and is correspondingly formed and carries out control air distribution in flame, Flame and outer flame, keeps combustion process more abundant, soon
Ignition temperature is improved fastly.Controllable secondary air distribution can be carried out to natural gas and be sufficiently mixed burning.Oxygen content can be effectively controlled,
Achieve the effect that low-nitrogen discharged.Biological fuel gas more fully efficiently, improves efficiency of combustion, while convenient fast in combustion
Victory is switched to the combustion system using natural gas, meets the selection that same model burner adapts to pluralities of fuel.
The characteristics of the utility model：1, primary, secondary and three times air distribution be all made of eddy flow slot be oriented to air distribution, make air distribution with combustion
Gas mixing is more uniformly abundant, ensure that oxygen amount needed for combustion process.
2, biological fuel gas, natural gas can be used and individually carry out air distribution combustion, it is also possible to biological fuel gas, natural gas mixing
Burning, functional diversities.
3, using the burning fire door of taper, conducive to air distribution with combustion gas being sufficiently mixed in the region, the flame of ejection is more
Strongly, full.
Description of the drawings
Fig. 1 is the structural schematic diagram of biological fuel gas and natural gas dual burner.
Fig. 2 is guide shell and the sectional view at air distribution diffusion disc assembly.
Specific implementation mode
As shown in Figure 1, biological fuel gas and natural gas dual burner mainly by biomass fuel gas port 1, secondary air chamber 3,
Guide shell 2, natural gas channel 8 and taper fire door 9 form.
The inside of biomass fuel gas port 1 is embedded in guide shell 2, and outer support 11 is arranged on the outside of guide shell, biomass fuel gas port 1
Secondary air chamber 3 is arranged in outside, and the outside suit conical furnace mouth 9 of secondary air chamber 3, natural gas channel 8 is arranged in taper fire door 9.It is secondary
Air compartment 3 connects secondary air channel 4, and secondary air chamber provides secondary air distribution.Tertiary-air pipe 6 and natural gas line are connected in natural gas channel 8
7, natural gas channel provides air distribution and natural gas three times.The madial wall of guide shell is provided with several eddy flow slots of spiral configuration
(piece) 2.1, the space formed between 2 outside of guide shell and 9 inside of taper fire door are connected to secondary air chamber 3 to generate secondary air distribution
Burning.The exit setting air distribution diffusion disc 10 of secondary air chamber 3, the exit setting Gas diffusion disk 5 in natural gas channel 8,
The structure of Gas diffusion disk 5 is identical as air distribution diffusion disc 10.The main body of air distribution diffusion disc 10 is circulating line, in circulating line
The eddy flow slot 10.1 of interior setting spiral configuration.It is adjoint while biomass fuel gas port 1 inputs biological fuel gas to be mixed into First air.
The combustion gas that gasification of biomass room generates is sprayed through biological fuel gas outlet 1 and water conservancy diversion inner cylinder 2 under the action of First air and is burnt, and one
Secondary wind carries out air distribution by water conservancy diversion inner cylinder and eddy flow slot.
First air carries out air distribution combustion by the eddy flow slot of inner cylinder to the internal flame position of flame；Secondary Air passes through secondary air channel
4, secondary air chamber 3, the incision of air distribution diffusion disc 10 carry out air distribution combustion to the middle flame position of flame；Tertiary air by tertiary-air pipe 6,
Gas diffusion disk 5 is cut carries out air distribution combustion to the flame envelope of flame；Natural gas passes through natural gas line 7 and Gas diffusion disk
5 spray burning, and secondary air channel 4, secondary air chamber 3 and air distribution diffusion disc 10 carry out air distribution combustion to natural gas.
According to the length of boiler furnace, change natural gas, the angle of air distribution diffusion disc eddy flow slot can control combustion flame
Length.
