Description
Technical field
The invention belongs to biomass gasification equipment, and biological fuel gas and combustion of natural gas are used more particularly to boiler body
Device.
Technical background
The burner of the gas outlet of biomass gasifying furnace at present, can only combustion caused by single biomass burning gasification
Gas, and be incorporated once, secondary air distribution still can not ensure that biological fuel gas burns cinder completely, it is flammable containing not burning down in flue gas
Property the increase of gas probability, greatly reduce biomass gasification fired thermal energy conversion efficiency.When running into biomass fuel feelings in short supply
Under condition, can not use other fuel carry out quick replacement, be switched fast burning, so occur because fuel supply problem and caused by
Halt production phenomenon occurs for thermal break.
The content of the invention
For the present invention in order to solve the above problem, the present invention provides a kind of adapted biomass combustion gas and the dual-purpose switching of natural gas
Burn to ensure the lasting burner for thermal energy.
In order to realize the above object the present invention adopts the technical scheme that what is be implemented：A kind of biological fuel gas and day
Right gas dual burner, including biomass fuel gas port, biomass fuel gas port are passed through biological fuel gas and First air, the biomass
The inner side of gas port sets guide shell, and primary combustion air distribution combustion is produced in guide shell, and the outside of biomass fuel gas port sets two
Secondary air compartment, the outside suit conical furnace mouth of the secondary air chamber, the taper fire door set natural gas passage, on the outside of guide shell with
The space formed between on the inside of taper fire door is connected with secondary air chamber, and natural gas passage connects tertiary-air pipe.
Further, the madial wall of the guide shell sets some eddy flow grooves of spiral configuration.
The exit of the secondary air chamber sets air distribution diffusion disc.
The exit of the natural gas passage sets Gas diffusion disk.
Implement technical solution of the present invention, carried out once for the combustion gas that is produced after gasification of biomass, is secondary, grade separation three times
Wind burns, and is correspondingly formed and is controlled air distribution in flame, Flame and outer flame, makes combustion process more abundant, rapidly
Improve ignition temperature.Controllable secondary air distribution can be carried out to natural gas and be sufficiently mixed burning.Oxygen content can be effectively controlled, is reached
Low-nitrogen discharged effect.Biological fuel gas more fully efficiently, improves efficiency of combustion, while convenient and efficient cut in combustion
The combustion system using natural gas is changed to, meets the selection that same model burner adapts to pluralities of fuel.
The features of the present invention：1st, once, it is secondary and three times air distribution using eddy flow groove be oriented to air distribution, air distribution is mixed with combustion gas
Conjunction is more uniformly abundant, ensure that oxygen amount needed for combustion process.
2nd, biological fuel gas, natural gas can be used individually to carry out air distribution combustion, it is also possible to biological fuel gas, natural gas mixing
Burning, functional diversities.
3rd, using the burning fire door of taper, beneficial to air distribution with combustion gas being sufficiently mixed in the region, the flame of ejection is more
Strongly, it is full.
Brief description of the drawings
Fig. 1 is the structure diagram of biological fuel gas and natural gas dual burner.
Fig. 2 is guide shell and the sectional view at air distribution diffusion disc assembling.
Embodiment
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 passage 8 and taper fire door 9 form.
The inner side of biomass fuel gas port 1 is embedded in guide shell 2, and outer support 11 is set on the outside of guide shell, biomass fuel gas port 1
Outside sets secondary air chamber 3, and the outside suit conical furnace mouth 9 of secondary air chamber 3, taper fire door 9 sets natural gas passage 8.It is secondary
Air compartment 3 connects secondary air channel 4, and secondary air chamber provides secondary air distribution.Natural gas passage 8 connects tertiary-air pipe 6 and natural gas line
7, natural gas passage provides air distribution and natural gas three times.The madial wall of guide shell is provided with some eddy flow grooves of spiral configuration
(piece) 2.1, the space formed between the outside of guide shell 2 and the inner side of taper fire door 9 are connected to produce secondary air distribution with secondary air chamber 3
Burning.The exit of secondary air chamber 3 sets air distribution diffusion disc 10, and the exit of natural gas passage 8 sets Gas diffusion disk 5,
The structure of Gas diffusion disk 5 is identical with air distribution diffusion disc 10.The main body of air distribution diffusion disc 10 is circulating line, in circulating line
The interior eddy flow groove 10.1 that spiral configuration is set.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 produces is sprayed through biological fuel gas outlet 1 and water conservancy diversion inner cylinder 2 under the action of First air and burnt, and one
Secondary wind carries out air distribution by water conservancy diversion inner cylinder and eddy flow groove.
First air carries out air distribution combustion by the eddy flow groove of inner cylinder to the internal flame position of flame；Secondary Air passes through secondary air channel
4th, secondary air chamber 3, air distribution diffusion disc 10 are cut carries 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 groove can control combustion flame
Length.
