Summary of the invention: the purpose of this utility model is design a kind of biomass fuel, a reverse burning semi-coal gas boiler, and it is explosion-proof and coal gas is collected, heat energy utilization is abundant, the problem of smoke abatement and dust control and raising heat-transfer effect to be used for overcoming and to solve boiler; Biomass fuel, reverse burning semi-coal gas boiler is by hopper, wireway, the water-cooled interlayer, igniting, give the wind hole, fire door, water-cooled grate, convection bank, blast pipe, outlet pipe, exhaust opening, burner hearth, convection bank district and return pipe are formed, the upright top that is contained in burner hearth of hopper, wireway is installed in hopper and the burner hearth, the top of boiler and wall are the water-cooled interlayer, igniting, give the wind hole, fire door is installed on the antetheca of boiler, return pipe and outlet pipe are installed the lower end and the upper end of water-cooled interlayer respectively, water-cooled grate is installed in the below of burner hearth and is communicated with the water-cooled interlayer, convection bank is installed in the below of water-cooled grate and the convection bank district and with the water-cooled interlayer and is communicated with, the blast pipe that communicates with the water-cooled interlayer of top, convection bank district is installed on the water-cooled interlayer of hopper lower side, exhaust opening is installed in the top of the rear wall of water-cooled interlayer, and the heat supply water pipe is installed in the top of water-cooled interlayer rear wall.
The utility model is applicable to the rural resident ' s family heating, heat supply water, and the heating medium is a water.
The beneficial effects of the utility model, advantage and characteristics:
1, simple in structure, produce, easy to manufacture, cost is low, be fit to farmers' family and buy, install and use;
2, fuel source is extensive, inexpensive, is fuel with agricultural waste material such as straw, rice husk, corncob, excrement of animals, has changed fuel structure, turns waste into wealth, and reduces the heating cost significantly, saves coal consumption;
3, by the reverse burning of semi-coal gasization, can make the abundant after-flame of fuel, environmental protection, easy to use.
4, have that coal gas is collected, boiler is explosion-proof, heat energy utilization is abundant, the beneficial effect of smoke abatement and dust control and raising heat-transfer effect.
Description of drawings:
Accompanying drawing is the utility model structure vertical section right side view.
Among the figure: 1. hopper, 2. wireway, 3. water-cooled interlayer, is given the wind hole at 4. igniting, 5. fire door, 6. water-cooled grate, 7. convection bank, 8. blast pipe, 9. outlet pipe, 10. exhaust opening, 11. burner hearths, 12. convection bank districts, 13. return pipes, 14. heat supply water pipes.
The specific embodiment:
Below in conjunction with accompanying drawing concrete structure of the present utility model and embodiment are described again once
Concrete structure
As shown in drawings: biomass fuel, reverse burning semi-coal gas boiler is by hopper 1, wireway 2, water-cooled interlayer 3, igniting, give wind hole 4, fire door 5, water-cooled grate 6, convection bank 7, blast pipe 8, outlet pipe 9, exhaust opening 10, burner hearth 11, convection bank district 12 and return pipe 13 are formed, the hopper 1 upright top that is contained in burner hearth 11, wireway 2 is installed in hopper 1 and the burner hearth 11, the top of boiler and wall are water-cooled interlayer 3, igniting, give wind hole 4, fire door 5 is installed on the antetheca of boiler, return pipe 13 and outlet pipe 9 are installed the lower end and the upper end of water-cooled interlayer 3 respectively, water-cooled grate 6 is installed in the below of burner hearth 11 and is communicated with water-cooled interlayer 3, convection bank 7 is installed in the below of water-cooled grate 6 and the convection bank district 12 and with water-cooled interlayer 3 and is communicated with, the blast pipe 8 that communicates with the water-cooled interlayer 3 of 12 tops, convection bank district is installed on the water-cooled interlayer 3 of hopper 1 lower side, exhaust opening 10 is installed in the top of the rear wall of water-cooled interlayer 3, and heat supply water pipe 14 is installed in the top of water-cooled interlayer 3 rear walls.
Embodiment
As shown in drawings: fuel is added by hopper 1 top, directly drop on the water-cooled grate 6, after filling fuel, by the igniting on the antetheca of water-cooled grate 6 top boilers, to directly fuel being ignited in wind hole 4, the high temperature of flame can make the water temperature in the water-cooled interlayer 3 raise, and flame is lighting a fire, giving wind hole 4 under the wind action by behind the water-cooled grate 6, water temperatures in the convection bank 7 are raise have washed away the outer wall of convection bank 7 again, make heat energy utilization fully, smoke abatement and dust control and improved heat-transfer effect; Fuel is in the process of burning, coal gasification reaction can take place, most the direct burning of coal gas that produces, some coal gas accumulates in the top in the hopper 1, lighting a fire, giving wind hole 4 under the wind action, the burner hearth 11 that can be introduced into the bottom by wireway 2 these part coal gas burns, and furnace temperature is raise got rid of the possibility of gas leakage again, also prevented the bursting of boilers, safe and reliable; High temperature in the stove can make the water temperature in water-cooled interlayer 3 and the convection bank 7 raise, and sends into the purpose that indoor warmer reaches heating through outlet pipe 9; In the process of burning heating, blast pipe 8 can make the gases that produce in the water-cooled interlayer 3 on burner hearth 11 tops be discharged to send in the water-cooled interlayer 3 on 12 tops, convection bank district and through outlet pipe 9 again drains through air bleeding valve, has guaranteed the safe handling of boiler; Fuel in the hopper 1 can reach two hours through the time of test measuring and calculating after-flame, solved the excessive introducing of the caused cold air of the frequent refuelling of conventional small-sized hand-fired boiler, cause the difficult problem that furnace temperature is low, heat loss due to exhaust gas is high, simultaneously also make the utility model possess the advantage easy to operate, that labour intensity is low, in addition, the utility model can also provide life hot water by heat supply water pipe 14.
