Summary of the invention
Technical problem to be solved in the utility model provides a kind of combustion furnace that utilizes a large amount of organic waste in rural area, saves the used organic granular fuel of coal-fired and protection environment.
The technical scheme that solves the problems of the technologies described above is:
A kind of combustion furnace that uses organic granular fuel, it is by body of heater, burner hearth, the heating water jacket, fire grate is formed, furnace body outer wall is a metal shell, the heating water jacket is looped around the top of burner hearth, between heating water jacket and the furnace body outer wall heat-insulation layer is arranged, fire grate is in the bottom of burner hearth, its improvements are, it also has a combustion-supporting fire grate, combustion-supporting fire grate is taper, and cone wall is made up of spaced bonding jumper, and is gapped between the adjacent metal bar, the two ends up and down of bonding jumper are connected as one by quoit respectively, and the quoit of the cone bottom of combustion-supporting fire grate is placed on the upper face center of fire grate.
The above-mentioned combustion furnace that uses organic granular fuel, it also has a plurality of hoppers, and hopper is around the periphery that is arranged in body of heater, and tremie pipe is arranged at the hopper bottom, and tremie pipe passes insulating layer of furnace body, and tremie pipe is in the hearth wall upper shed.
The above-mentioned combustion furnace that uses organic granular fuel, the height of described combustion-supporting fire grate are 230-250mm, and the upper opening diameter is 18-24mm, lower openings diameter 260-300mm.
The above-mentioned combustion furnace that uses organic granular fuel has ash bin below fire grate, ash bin is removable the connection with body of heater.
Adopt the combustion furnace of the used organic granular fuel of this structure, the use that agriculture organic matters such as stalk can be acted as a fuel, the combustion-supporting fire grate of taper can play the effect of ventilating and putting a chimney on the stove and make the fire draw, and makes burning more abundant, and hopper can be realized automatic feed.That this device has is simple in structure, it is easy, with low cost to make, save coal-fired, as to reduce environmental pollution remarkable result, is a kind of energy-saving and emission-reduction product that is worthy to be popularized.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Mark is as follows among the figure: body of heater 1, burner hearth 2, heating water jacket 3, heat-insulation layer 4, fire grate 5, combustion-supporting fire grate 6, bonding jumper 7, quoit 8, hopper 9, tremie pipe 10, ash bin 11
The specific embodiment
Show among the figure that the utility model is made up of body of heater 1, burner hearth 2, heating water jacket 3, fire grate 5.
The outer wall of body of heater 1 is the steel plate welding, and heating water jacket 3 is looped around the top of burner hearth 2, and heat-insulation layer 4 is arranged between heating water jacket 3 and the furnace body outer wall, and fire grate 5 is in the bottom of burner hearth 2, and these structures all have application on a lot of warming stoves or drinking water boiler, belong to mature technique.
Special feature of the present utility model is that agriculture organic matters such as wheat straw, maize straw are acted as a fuel, and reaches to save purpose coal-fired and the minimizing smoke pollution, has also digested a large amount of discarded organic matters simultaneously, and the operating cost of combustion furnace is reduced greatly.
The fuel that the utility model uses is wheat straw or the maize straw that is ground into the 8-12mm particle by pulverizer, in order to make this granular fuel burning more abundant, the utility model has increased a combustion-supporting fire grate 6, combustion-supporting fire grate 6 is taper, cone wall is made up of spaced bonding jumper 7, gapped between the adjacent metal bar 7, the two ends up and down of bonding jumper 7 are connected as one by quoit 8 respectively, and the quoit 8 of the cone bottom of combustion-supporting fire grate 6 is placed on fire grate 5 upper face center of burner hearth 2 bottoms.Above-mentioned combustion-supporting fire grate 6 can be welded by reinforcing bar, also can integral casting forming.The height of the combustion-supporting fire grate 6 of present embodiment is 240mm, back cut diameter 20mm, lower port diameter 280mm.
