Background technique
Biomass energy is the energy that lived plant provides in nature.These plants are using biomass as medium storing
Solar energy, the energy used in human history earliest is biomass energy, and before latter half in 19th century, the energy of human use is with firewood
Based on bavin.In current world energy sources structure, biomass energy proportion is very little.Harmful substance in biomass energy contains
Amount is very low, belongs to clean energy resource.Meanwhile the conversion process of biomass energy is by the photosynthesis of green plants by titanium dioxide
At biomass, the use process of biomass energy generates carbon dioxide and water again for carbon and hydration, forms the circulation row of carbon dioxide
Journey is let off, the net discharge amount of mankind's carbon dioxide can be effectively reduced, reduces greenhouse effects.
Biomass energy can be converted into conventional solid-state, liquid and fuel gas, inexhaustible, nexhaustible, be that one kind can
The renewable sources of energy.Biomass pyrogenation gasification technology is biomass in high temperature (850~950 DEG C) anoxic (air excess 0.25~0.3)
Under the conditions of imperfect combustion, be converted to the technology of high-temperature fuel gas, the principal combustible components of combustion gas are CO, Ch4, H2 etc., temperature
It is 350~450 DEG C, existing biological fuel gas applies biological fuel gas range since the temperature of its discharge is more constant
It is relatively narrow, and existing biological fuel gas is often wasted due to the inconvenience of its Collection utilization, therefore the prior art needs further
Improvement.
Summary of the invention
The purpose of this utility model is to provide one kind, and biogas can be made full use of to generate heat, and controllable life
The biological fuel gas special hot air stove of flue-gas temperature after the burning of substance gas.
Based on above-mentioned purpose, the utility model adopts the following technical scheme:
A kind of biological fuel gas special hot air stove, including into gas chamber, be equipped with into gas chamber into gas port, into gas chamber
It is interior to run through first passage, first passage upper end closed and it is located at into above gas chamber, positioned at into the first passage above gas chamber
Side wall be equipped with first into air scoop and liquefied gas inlet, ignitor is equipped in first passage, into gas chamber below be connected to
The lower end of second channel, first passage is protruded into second channel, is had between the side wall of first passage and the side wall of second channel
Interval, second channel are arranged air chamber outside, and second channel is connected to air chamber by first through hole band, and air chamber has burner hearth,
Burner hearth is connected to by the second through-hole band below air chamber, second channel lower end is protruded into burner hearth, be additionally provided on air chamber second into
Air scoop, burner hearth sidewall are equipped with outlet flue, connect ash hopper below burner hearth.
Further, the perforated area ratio of the perforated area of the first through hole band and the second through-hole band is 1:2.
Further, the lower section of the second channel is conical outlet.
Further, described into entering biogas in gas chamber.
Further, the outlet flue is located at the middle section of burner hearth.
The utility model can sufficiently burn biogas, can make full use of biogas, and adjustable combustion
Flue-gas temperature after burning expands its application range, and easy to use, structure is simple, saves the energy.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the cross-sectional view of A-A in Fig. 1；
Fig. 3 is the cross-sectional view of D-D in Fig. 2.
Specific embodiment
A kind of biological fuel gas special hot air stove as shown in Figs. 1-3, including into gas chamber 1, into gas chamber 1 be equipped with into
Gas port 101, into gas chamber 1 in run through first passage 2,2 upper end closed of first passage and be located at into the top of gas chamber 1, be located at
Side wall into the first passage 2 of the top of gas chamber 1 is equipped with first into air scoop 3 and liquefied gas inlet 4, sets in first passage 2
Have ignitor 5, into gas chamber 1 below be connected to second channel 6, the lower end of first passage 2 protrudes into second channel 6, and first is logical
There is interval between the side wall in road 2 and the side wall of second channel 6, be arranged air chamber 7 outside second channel 6, second channel 6 passes through the
One through-hole band 8 is connected to air chamber 7, and air chamber 7 has burner hearth 10, passes through the second through-hole band 9 connection burner hearth below air chamber 7
10,6 lower ends are protruded into burner hearth 10, and second is additionally provided on air chamber 7 into air scoop 13, and 10 side wall of burner hearth is equipped with outlet flue 11,
The perforated area of connection ash hopper 12 below burner hearth 10, the perforated area of the first through hole band 8 and the second through-hole band 9 is 1:
2, the lower section of the second channel 6 is conical outlet, described into entering biogas, the outlet flue in gas chamber 1
11 are located at the middle section of burner hearth 10.
In use, be passed through air to first into air scoop 3, liquefied gas is passed through to liquefied gas inlet 4, and ignitor 5 is by liquid
The mixed gas for changing gas and air is lighted, to the high-temperature biomass gas being passed through into gas port 101 from gasification furnace out, biogas
Into in second channel 6, blast air into air chamber 7 from second into air scoop 13, into air chamber 7 air a part from
First through hole band 8 enters in the cavity between first through hole band 8 and 6 lower end of second channel, the air and biogas of the part
First time burning is carried out after mixing between 6 lower end of first through hole band 8 and second channel, then imperfect combustion biogas
Body enters in burner hearth 10, at the same time, enters furnace into another part air in the air of air chamber 7 from the second through-hole band 9
Intracavitary, the air of imperfect combustion biomass gas and the part occurs second and burns, the life after burning in burner hearth 10
Substance gas generate flue gas from outlet flue 11 be discharged, when need flue gas temperature it is lower when, second can be increased into air scoop 13
Air intake be when the flue-gas temperature of needs is higher similarly, it is possible to reduce second into air scoop 13 air intake,
Impurity after burning falls into ash hopper 12.
Since the perforated area of first through hole band and the perforated area ratio of the second through-hole band are 1:2, air is through first through hole
Enter the tolerance of second channel 6 with 8 and enters the tolerance of burner hearth through the second through-hole band 9 than being about 1:2, when needing high-temperature flue gas
When, the theoretical air requirement when air total amount of entrance is biological fuel gas completely burned, the combustion system of biological fuel gas is portion
Divide premixed combustion, the premix amount of air is the 1/3 of theoretical air requirement.When needing lower flue-gas temperature, increase air capacity, one
Secondary air incrementss are the 1/3 of total incrementss, ensure that being normally carried out for burning, when increased air capacity is theoretical air requirement
At 3 times, primary air amount is the clean-burning theoretical air requirement of combustion gas, and biomass combustion also can normal combustion.
