Abstract
The utility model discloses a kind of low-caloricity gas burner: comprise housing, described enclosure interior is disposed with interior mixed zone, fully mixing section and burning zone; Described housing is provided with air intlet, fuel gas inlet and ever-burning flame igniting unit; Mixing tube and secondary uniform board is disposed with in abundant mixing section in described housing; Gas secondary mixed zone is provided with between described secondary uniform board and mixing tube.Combustion gas and the combustion air of the utility model low-caloricity gas burner enter combustion chamber respectively by guide vane, carry out premixed in interior mixed zone, fully mixed by mixing auger in mixing tube, can ensure that low heat value biomass combustion gas is conveniently lighted and burns, simultaneously, hybrid mode can be adjusted by the front and back of combustion zone, ensure in mixing tube and mixing auger is not gathered rear blocking by tar.
Description
Technical field
The utility model relates to a kind of gas combustion apparatus, particularly a kind of low-caloricity gas burner.
Background technology
Due to the popularity of natural gas applications and reserves limited, the application of living beings fuel gas with low heat value receives publicity day by day.But living beings fuel gas with low heat value low heat value, not easily light and burn and cause living beings fuel gas with low heat value to be hindered in the application of natural gas motorcar occasion.Simultaneously because gasification of biomass is a kind of conventional biomass energy switch technology, in gasification, tar is inevitable accessory substance.
At high temperature can there is cracking in tar, in gaseous state together with gasification gas, but when lower than 200 DEG C, just start to be condensed into liquid, become the sticky grease of black, affect that equipment for gasification is stable, safe operation, cause energy dissipation, reduce gasification efficiency; And the polynuclear aromatic race in tar ingredients forms serious harm when purifying and burn to environment and human health.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of mixing fully, and combustion zone is adjustable, without the low-caloricity gas burner of blocking.
For solving the problems of the technologies described above, a kind of low-caloricity gas burner of the utility model, comprises housing, and described enclosure interior is disposed with interior mixed zone, fully mixing section and burning zone; Described housing is provided with air intlet, fuel gas inlet and ever-burning flame igniting unit, and described air intlet, fuel gas inlet are positioned on mixed zone, and described ever-burning flame igniting unit is positioned on burning zone; Be disposed with mixing tube and secondary uniform board in abundant mixing section in described housing, described mixing tube is connected with housing by Gas Pipe bulkhead bracket, is provided with at least one mixing auger in described mixing tube simultaneously; Gas secondary mixed zone is provided with between described secondary uniform board and mixing tube, one end mouth of pipe of described mixing tube is communicated with interior mixed zone, the other end mouth of pipe is communicated with gas secondary mixed zone, described housing comprises the heat-insulation layer and shell that set gradually from inside to outside, described secondary uniform board is provided with gas mixed hole, and described gas mixed hole is evenly distributed on secondary uniform board.
The head number of described mixing auger is two.
Low-caloricity gas burner of the present utility model compared to existing technology, there is following beneficial effect: combustion gas and combustion air are led to and carry out premixed in interior mixed zone, fully mixed by mixing auger in mixing tube, this ensure that low heat value biomass combustion gas is conveniently lighted and burns, simultaneously, hybrid mode can be adjusted by the front and back of combustion zone, ensure in mixing tube and mixing auger is not gathered rear blocking by tar.

Detailed description of the invention
Embodiment 1
As depicted in figs. 1 and 2, a kind of low-caloricity gas burner: comprise housing 1, described housing 1 inside is disposed with interior mixed zone 3, fully mixing section and burning zone 8; Described housing 1 is provided with air intlet 2, fuel gas inlet 4 and ever-burning flame igniting unit 9, and described air intlet 2, fuel gas inlet 4 are positioned on mixed zone 3, and described ever-burning flame igniting unit 9 is positioned on burning zone 8; Be disposed with mixing tube 5 and secondary uniform board 7 in abundant mixing section in described housing 1, described mixing tube 5 is connected with housing 1 by Gas Pipe bulkhead bracket 10, is provided with at least one mixing auger 6 in described mixing tube 5 simultaneously; Gas secondary mixed zone is provided with between described secondary uniform board 7 and mixing tube 5, one end mouth of pipe of described mixing tube 5 is communicated with interior mixed zone 3, the other end mouth of pipe is communicated with gas secondary mixed zone, described housing 1 comprises the heat-insulation layer 11 and shell 12 that set gradually from inside to outside, described secondary uniform board 7 is provided with gas mixed hole, and described gas mixed hole is evenly distributed on secondary uniform board 7.
The head number of described mixing auger 6 is two.
During work, first ever-burning flame igniting unit 9 is lighted, combustion gas is from fuel gas inlet 4, combustion air enters housing 1 respectively from air intlet 2 and tentatively mixes in interior mixed zone 3, mist fully mixes by entering next step during mixing tube 5 in mixing auger 6, mist is when secondary uniform board 7, mix more abundant because secondary uniform board 7 is evenly equipped with gas mixed hole, mixed fuel gas enters burning zone 8 burning under the lighting of ever-burning flame igniting unit 9, extinguishes ever-burning flame igniting unit 9 after flameholding.
Ever-burning flame igniting unit 9 first light when being and ensureing that air mixture enters burning zone 8 can burn, can not meet accident danger.
During normal combustion, combustion zone is in burning zone 8, after running a period of time, because the temperature of mixing section is relatively low, there is tar to accumulate in mixing tube 5 and mixing auger 6, adjust combustion zone by the ratio adjusting combustion gas and the air entered, combustion zone is adjusted to mixing tube 5 region, burning accumulating in mixing tube 5 with the tar on mixing auger 6, avoiding tar to block the gas path pipe of burning.
The above is only preferred embodiment of the present utility model; be noted that for those skilled in the art; under the premise without departing from the principles of the invention, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
