As illustrated in fig. 1 and 2, the cooking stove of biomass burning granular fuel according to embodiments of the present invention, including furnace body 24, life Material grains fuel charging device, air-supply assembly, flue gas heat exchange component, blower igniter and controller, furnace body 24 include up and down It arranges the chamber of a kitchen range 30 and burner hearth 21 of integrally connected and connection, places cooker on the chamber of a kitchen range 30, such as iron pan 28, which can pass through pot Support 29, the gap between 28 edge of iron pan and pot prop 29 are sealed using clay;21 lower part of burner hearth is equipped with fire grate 20, fire grate 20 and furnace Wind chamber 19 is equipped between 24 bottom of thorax, 24 top of burner hearth is equipped with wind lumen 23, and wind lumen 23 is equipped with multiple wind being evenly arranged Hole 22, the diameter of air holes can be 3-5mm;The discharge port of biomass granule fuel feeding device is connected to burner hearth 24;On fire grate Air holes diameter may be 3-5mm, while can double as grey hole.
Air-supply assembly includes that header pipe 13 and the First air air supply tube 16, the Secondary Air that are connected to 13 one end of header pipe are sent Air hose 17 and pressure ventilation pipe 18,16 other end of First air air supply tube connect vented cavity 19;17 other end of Secondary Air air supply tube connects vented cavity Pipe 23;18 other end of pressure ventilation pipe is connected to the connection of biomass granule fuel feeding device top;
24 side of the chamber of a kitchen range is connected to chimney breast 25;Water pipe 27, the non-water inlet in the upper end of water pipe are arranged on chimney breast 25 32, the lower end of water pipe can connect tap 31;Water jacket 26 is arranged with outside water pipe 27;Blower igniter and controller signals connect It connects.
In certain embodiments, biomass granule fuel feeding device includes that material feeding box 2, feed pipe 4 and charging twist Dragon 5 has openable and closable hopper lid 1 on material feeding box 2;It is connected on the upside of 18 other end of pressure ventilation pipe and material feeding box 2;4 one end of feed pipe Upper lateral part is connected to 2 bottom of material feeding box, and the other end is discharge port;Feeding packing auger 5 be arranged in feed pipe 4 and be located at feed pipe The driving portion connection in 4 outsides;Feeding packing auger be can be hollow feeding packing auger.Specifically, driving portion is wind or electricity Machine.
Specifically, blower igniter includes igniting blower 9, igniting air supply tube 10 and igniter 15, air supply tube 10 1 of lighting a fire End is protruded into burner hearth 21, and the other end is located at outside burner hearth 21;Igniter 15 is mounted on igniting 10 one end of air supply tube and is located at fire grate 20 top positions, igniting blower 9 are mounted on igniting 10 other end of air supply tube, on igniter 15 and igniting blower 9 and controller Button ignition switch 7 connects.Thus, it is possible to be lighted a fire by igniter automatic start-stop, the free space of peasant household's ignition phase is increased, is mentioned The high success rate of igniting.
In certain embodiments, the pull rod 11 that fire grate 20 can be driven to move horizontally is connected on fire grate 20.Some In specific example, ash bucket 14 is equipped with below fire grate 20, thus, it is possible to quickly collect combust.
Specifically, air-supply assembly further includes breeze fan 12 and air quantity adjusting knob 6;Breeze fan 12 and air quantity adjust rotation Button 6 is connect with controller;Ignition light 8 can be set on controller.
The cooking stove of biomass burning granular fuel of the present invention can have the following course of work:
The biomass granule fuel of suitable weight is added in material feeding box 2 before igniting, covers tightly hopper lid 1, is rotated hand Handle 3 drives feeding packing auger 5 to rotate, and biomass granule fuel is sent through feed pipe 4 to burner hearth 21, is dropped down on fire grate 20, until raw Material grains fuel is accumulated to only slight beyond height where igniter 15, presses the igniting of button ignition switch 7, the heat that igniter 15 generates heat Amount is sent into burner hearth 21 by the air-supply of igniting blower 9 and heats fuel to burning, and igniter 15 and igniting blower 9 are automatic after three minutes It stops working, breeze fan 12 is in running order during entire cooking, and minimum air quantity by that can not be threaded to zero span completely The control of air quantity adjusting knob 6 be greater than zero, the air-supply of breeze fan 12, sub-fraction is sent to material feeding box 2 by pressure ventilation pipe 18 Top, prevent down cigarette, remaining air quantity a part send air-inlet chamber 19 by First air air supply tube 16, and another part passes through Secondary Air Air supply tube 17 is sent into wind lumen 23, and First air enters burner hearth 21 by the air holes on fire grate 20, for biomass granule fuel Primary combustion, a large amount of imperfect combustion products in the flue gas of generation are when passing through 21 top of burner hearth, and via wind lumen 23 The Secondary Air mixing that air holes 22 is sent out, burns more abundant, reduces the pollutant concentration in flue gas, and the higher flue gas of temperature is logical Exchange heat when crossing chimney 25 with the water in water jacket 26 and the water pipe of cross arrangement straggly 27, water in water jacket 27 by upper end into The mouth of a river 32 supplements, and is released by the tap 31 of lower end.
During cooking in material feeding box when fuel quantity deficiency, opens hopper lid 1 and add fuel, additive amount should not be excessive, answers It measures and substantially determines according to demand, hopper lid 1 is first covered tightly after charging, shake wind 3 and pass through fuel in feed pipe 4 Feeding packing auger 5 is sent to burner hearth 21;When completion of combustion, wind 3 is first shaken by material feeding box 2, remaining a small amount of particle in feed pipe 4 Fuel shakes prevents a small amount of particle fuel of heating from smoldering in feed pipe 4 into burner hearth 21, is then shut off power supply, and level, which pulls, draws Bar 11 drives fire grate 20 to move horizontally, and remaining ash and uncombusted fuel fall fire grate 20 under the blocking of 21 inner wall of burner hearth above It falls in the ash bucket 14 of lower section, level pulls out ash bucket ash discarding, and ash bucket is then pushed into furnace body and is compressed.
The foregoing is merely presently preferred embodiments of the present invention, is not intended to limit the invention, it is all in spirit of the invention and Within principle, any modification, equivalent replacement, improvement and so on be should all be included in the protection scope of the present invention.
