China is a big agricultural country, straw treatment is a national problem all the time, about 8 million tons of straws are produced every year, about 3.4 million tons of straws can be used as fuel except part of straws used as paper making raw materials, livestock feeds and the like, and the quantity of straws is reduced to 17000 million tons of standard coal. According to policy and environmental protection requirements of China, coal burning is not allowed for 20-ton boilers and the output of a plurality of biomass burners cannot be large, so that the medium-sized boiler cannot be changed into biomass burning. The existing biomass burner only can burn good materials when picking materials, and the materials with large water content and large ash content of fuel cannot be burned, so that the price of the good fuel is always in the rising trend of price.
The existing biomass burner has the serious problem of coking, mainly because the circular fire outlet area is small, the inner wall of the circular fire outlet is easy to coke, the coking is generated and accumulated, the fire outlet is blocked, the area of the fire outlet is smaller and smaller, the power output is insufficient, the heat transmission is not smooth, dense smoke heat can be generated, the detonation danger is generated, and major accidents are easily caused.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is to overcome prior art not enough and provide a novel biomass briquette fuel combustor go out fire device, increased the area of going out fire of combustor, reduced the coking phenomenon of going out fire.
In order to solve the technical problem, the utility model discloses the technical scheme who takes is:
a fire outlet device of a novel biomass briquette combustor is arranged outside a fire outlet on the side wall of a hollow cylindrical combustion chamber; comprises a square arched door-shaped fire outlet channel; a plurality of transverse air distribution air inlet pipes are respectively embedded in the left side wall and the right side wall of the fire outlet channel, and air inlets at the outer ends of the air distribution air inlet pipes in the left side wall and the right side wall are respectively communicated with air distribution branch pipes arranged on the left side and the right side of the fire outlet channel; and the air inlet ends of the air distribution branch pipes on the left side and the right side are connected with an air distribution main pipe connected with an air outlet of the air distribution machine.
Furthermore, the projection of the fire outlet on a plane perpendicular to the central line of the fire outlet channel is also in a square arch shape.
Furthermore, the fire outlet channel comprises a fire outlet fire-resistant layer, a fire outlet heat-insulating layer and a fire outlet outer skin which are sequentially arranged from inside to outside; the air distribution air inlet pipe sequentially penetrates through the fire outlet outer skin, the fire outlet heat insulation layer and the fire outlet fire-resistant layer from outside to inside.
Furthermore, the fire outlet fire-resistant layer and the inner fire-resistant layer of the combustion chamber are of an integrated structure; and the inner end of the fire outlet outer skin is provided with a fire outlet flange connected with the outer skin of the combustion chamber.
Adopt the produced beneficial effect of above-mentioned technical scheme to lie in:
the utility model adopts the square arched door-shaped fire outlet channel, when being applied to the burner, the fire outlet area of the burner is increased, so that the fire outlet is not easy to coke, and the deflagration phenomenon is reduced; because the internal area of the fire outlet is large, sudden power failure does not have the heat expansion danger.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 1-3, the utility model discloses a fire outlet device of a novel biomass briquette combustion machine, which is arranged outside a fire outlet on the side wall of a hollow cylindrical combustion chamber 4; comprises a square arched door-shaped fire outlet channel 7; the projection of the fire outlet on a plane vertical to the central line of the fire outlet channel 7 is also in a square arch shape. A plurality of transverse air distribution air inlet pipes 46 are respectively embedded in the left side wall and the right side wall of the fire outlet channel 7, and air inlets at the outer ends of the air distribution air inlet pipes 46 in the left side wall and the right side wall are respectively communicated with air distribution branch pipes 45 arranged at the left outer side and the right outer side of the fire outlet channel 7; the air inlet ends of the air distribution branch pipes 45 on the left side and the right side are connected with an air distribution main pipe 44 which is connected with an air outlet of the air distribution machine 10.
