Description
Technical field
The utility model relates to a kind of boiler, particularly a kind of biomass shaped fuel boiler.
Background technology
At present, existing biomass shaped fuel boiler, because it is provided with a ventilation unit, thus the intake in burner hearth is insufficient, thus the burning easily causing biomass molding fuel is abundant not, and black smoke of emerging frequently, and thus efficiency of combustion is lower and pollute comparatively serious.
In addition, existing biomass shaped fuel boiler, its feed mechanism is when feeding, fuel is easily deposited in charging aperture place, is blocked by charging aperture, so, need boiler staff material toggling frequently, thus increased the weight of the workload of boiler staff, reduce operating efficiency.
Summary of the invention
Problem to be solved in the utility model is: provide that a kind of structure is simple, thus sufficient combustion can reduce and to pollute and need not the biomass shaped fuel boiler of manual material toggling.
In order to solve the problems of the technologies described above, biomass shaped fuel boiler of the present utility model, comprise upper furnace body and lower furnace body, fire grate is provided with in described lower furnace body, the top of described fire grate is fixed with secondary blast case, described secondary blast case is annular, the top of described secondary blast case is evenly equipped with some secondary blast pipes, described secondary blast pipe is connected with secondary blast case, the outside of described lower furnace body is provided with the blower fan mouth of connecting fan, and the inner of described blower fan mouth is connected with secondary blast case.
Further, in order to wind better blows to fuel to improve the efficiency of combustion of fuel, biomass shaped fuel boiler of the present utility model, the inner side of described secondary blast pipe is provided with several fresh air inlets, described fresh air inlet is tilted to down, and the angle of described fresh air inlet and horizontal plane is 30-60 °.
Further, biomass shaped fuel boiler of the present utility model, the angle of described fresh air inlet and horizontal plane is 45 °.
In order to avoid fuel is piled up on feed surge plate, boiler workman is made no longer to need material toggling, biomass shaped fuel boiler of the present utility model, the external stability of described lower furnace body has feed bin, the below of described feed bin is provided with screw feeding device, described screw feeding device is inserted in lower furnace body, the below of the output of described screw feeding device is provided with one piece of blanking baffle of pressure, described lower furnace body is also fixed with booster type fuel intake stack, the opening of described booster type fuel intake stack is positioned at immediately below blanking baffle of pressure.
The beneficial effect that the utility model obtains is: (1) structure is simple, (2) fuel is when burning, the wind-force that blower fan produces is after secondary blast case and secondary blast pipe, the fuel burnt is blowed to by fresh air inlet, improve the content of the oxygen in the combustion chamber of lower furnace body, thus the unburnt subtitle substance in fuel is formed in combustion chamber revolve the burning of swimming vortex streaming, make fuel combustion thoroughly and emerge without black smoke, reducing the discharge of dust, improve the utilization rate of fuel, thus also make the thermal efficiency of boiler greatly improve, (3) fresh air inlet is tilted to down, thus makes secondary blast better blow to fuel, the further efficiency of combustion improving fuel, (4) below of feed bin is provided with screw feeding device, screw feeding device is inserted in lower furnace body, the below of the output of screw feeding device is provided with one piece of blanking baffle of pressure, lower furnace body is also fixed with booster type fuel intake stack, the opening of booster type fuel intake stack is positioned at immediately below blanking baffle of pressure, first the fuel carried by screw feeding device be transported on feed surge plate, then fuel falls from blanking baffle of pressure again, from the fuel that blanking baffle of pressure falls, can be blown away by the wind-force in booster type fuel intake stack timely, thus boiler workman is no longer needed to carry out artificial material toggling, thus reduce the amount of labour of boiler workman.

Detailed description of the invention
As depicted in figs. 1 and 2, biomass shaped fuel boiler of the present utility model, comprise upper furnace body 1 and lower furnace body 10, fire grate 9 is provided with in described lower furnace body 10, the top of described fire grate 9 is fixed with secondary blast case 7, described secondary blast case 7 is annular, the top of described secondary blast case 7 is evenly equipped with some secondary blast pipes 6, described secondary blast pipe 6 is connected with secondary blast case 7, the outside of described lower furnace body 10 is provided with the blower fan mouth 5 of connecting fan, and the inner of described blower fan mouth 5 is connected with secondary blast case 7; The inner side of described secondary blast pipe 6 is provided with several fresh air inlets 11, and described fresh air inlet 11 is tilted to down; Described fresh air inlet 11 is 45 ° with the angle of horizontal plane; The external stability of described lower furnace body 10 has feed bin 2, the below of described feed bin 2 is provided with screw feeding device 3, described screw feeding device 3 is inserted in lower furnace body 10, the below of the output of described screw feeding device 3 is provided with one piece of blanking baffle of pressure 8, described lower furnace body 10 is also fixed with booster type fuel intake stack 4, the opening of described booster type fuel intake stack 4 is positioned at immediately below blanking baffle of pressure 8.
Biomass shaped fuel boiler of the present utility model, structure is simple, fuel is when burning, the wind-force that blower fan produces is after secondary blast case 7 and secondary blast pipe 6, the fuel burnt is blowed to by fresh air inlet 11, improve the content of the oxygen in the combustion chamber of lower furnace body 10, thus the unburnt subtitle substance in fuel is formed in combustion chamber revolve the burning of swimming vortex streaming, make fuel combustion thoroughly and emerge without black smoke, reduce the discharge of dust, improve the utilization rate of fuel, thus also make the thermal efficiency of boiler greatly improve.
