Detailed description of the invention
Describe the present invention in detail below in conjunction with accompanying drawing and specific embodiment, in this signal of the present inventionProperty embodiment and explanation are used for explaining the present invention, but not as a limitation of the invention.
Embodiment
As shown in Figures 1 and 2, a kind of biomass double furnace thorax ultrahigh temperature combustion machine, comprising: loading hopper 1,Air blast 2, the first burner hearth 3 and the second burner hearth 4; Described loading hopper 1 is for loading biomass fuel,The discharging opening of its below is communicated with described the first burner hearth 3, and discharging opening place is provided with baffle plate, by handwheel 11The opening and closing of controlling baffle plate, described the first burner hearth 3 is for insufficient combustion for the first time of biomass fuelBurn, described the first burner hearth 3 is communicated with described the second burner hearth 4, and described the second burner hearth 4 is by tube connector 37Be provided with bocca 5, bocca 5 comprises inner tube 39 and outer tube 51, and wherein inner tube 39 connects with tube connector 37Logical, 51 of outer tubes are communicated with air blast 2 by connecting airduct 37, wherein the first burner hearth 3, the second burner hearth4 all adopt special refractory to make; The air outlet of described air blast 2 respectively by the first air inlet pipe 31,The second air inlet pipe 32 is communicated with described the first burner hearth 3, the second burner hearth 4.
By above-described embodiment scheme, biomass fuel is by the first air inlet pipe 31 oxygen supplys, at the first burner hearth 3Middle burn incompletely, the flue gas of generation enters the second burner hearth 4 under the guide functions of the first air inlet pipe 31,In the second burner hearth 4, by the second air inlet pipe 32 oxygen supplys, flue gas carries out gasification, and combustion, and ignition temperature is furtherImprove, flame sprays from bocca 5 under the guide functions in the second air inlet pipe 32.
As the improvement of above-described embodiment scheme, the discharging opening of described loading hopper 1 by feed pipe 12 withDescribed the first burner hearth 3 is communicated with, and in described feed pipe 12, is provided with follower arm, and described follower arm footpath is upwards provided withHelical blade, described spiral leaf bar is connected with drive unit 13, under the effect of follower arm, realizes living beingsThe quantitative constant speed of fuel is supplied with.
As the improvement of above-described embodiment scheme, the air outlet of described air blast 2 is by the 3rd air inlet pipe 33Be communicated with described feed pipe 12, make loading hopper 1 form negative pressure at discharging opening, accelerate on the one hand living beingsThe conveying of fuel, avoids biomass fuel to stop up, and also can reduce on the other hand follower arm, helical blade etc.The temperature of parts, in order to realize the first air inlet pipe 31, the second air inlet pipe 32 and the 3rd air inlet pipe 33Comprehensive Control, can by the air outlet of air blast 2 with establish valvular control cabinet 6 and be connected, control cabinet 6Be communicated with the first air inlet pipe 31, the second air inlet pipe 32 and the 3rd air inlet pipe 33 respectively.
