That the utility model originally has is simple in structure, the thermal efficiency is high, sufficient combustion, can not discharge black smoke, and advantage easy to use and with low cost.
Description of drawings
Fig. 1 is the cross-sectional view of a kind of embodiment of the utility model.
Fig. 2 is the perspective view of the combustion furnace of Fig. 1.
The specific embodiment
See also Fig. 1 and Fig. 2, what Fig. 1 and Fig. 2 disclosed is a kind of biomass powder combustor, at the uniform velocity charging gear 1, material gas mixing arrangement 2, combustion furnace 3 and oxygen-increasing device 4, described combustion furnace 3 is divided into just combustion chamber 31, afterflame chamber 32 and oxygenation combustion chamber 33 from bottom to up successively, and interior sky is full of twists and turns described just combustion chamber 31, afterflame chamber 32 and oxygenation combustion chamber 33 communicates; Described at the uniform velocity charging gear 1 links to each other with the charging aperture 21 of described material gas mixing arrangement 2, the discharging opening 22 of described material gas mixing arrangement 2 communicates with described just combustion chamber 31, described gas reinforcing device 4 communicates with described oxygenation combustion chamber 33, is provided with crater 34 in described oxygenation combustion chamber 33.
In the utility model, be provided with the first dividing plate 35 and second partition 36 in described combustion furnace 3, described the first dividing plate 35 and second partition 36 arrange in opposite directions, and with stove inwall 37 mutually across a certain distance, consist of full of twists and turns passage.Described combustion furnace 3 comprises inwall 37, heat-insulation layer 38 and shell 39, and described heat-insulation layer 38 is between described inwall 37 and shell 39.Described material gas mixing arrangement 2 is feeding fans.Described oxygen-increasing device 4 is air blasts.Described at the uniform velocity charging gear 1 comprises feed bin 11 and screw(-type) feeder 12, and described screw(-type) feeder 12 is positioned at the bottom of feed bin 11.
After the utility model adopts powder and air fully mixes, meet again the high temperature detonation and give birth to heat.The combustion chamber is made of high-temperature refractory, high temperature insulating material and box hat, combustion at the beginning of minute, afterflame and three parts of oxygenation, just carrying out in combustion chamber 31, afterflame chamber 32 and the oxygenation combustion chamber 33, can keep the high-temperature stable time respectively, can increase again powder and stop burning time.Material gas mixing arrangement 2 and oxygen-increasing device 4 are used VFC, and the continuous increase along with powder stream makes detonation become a succession of burning, and the heat energy stable output is desirable.
The utility model operation is as follows, lighting-up tuyere 40 usefulness diesel combustion machines in first combustion chamber 31 are heated to about 800 ℃, close subsequently lighting-up tuyere 40, change by material gas mixing arrangement 2 and continue to be blown into powder fuel, in just combustion chamber 31 interior detonations, open and regulate oxygen-increasing device 4, namely can obtain at crater 34 places desirable heat energy.The utility model adopts three grades of burnings, can reach clean-burning degree, after the burning, can not discharge black smoke from crater 34.
