Description
Technical field
The present invention relates to a kind of cooking stove, is mainly a kind of solid particle fuel cooking stove, particularly a kind of feeding structure of solid particle fuel cooking stove.
Background technology
Solid particle fuel mainly comprises biomass granule fuel, mineral particle fuel etc.
Biomass granule fuel is called for short biomass fuel, biomass fuel mostly is agricultural wastes and timber refuse is bulk (the being mainly cylindric) fuel that main (stem shape crops, peanut shell, bark, sawdust and solid waste (furfural dregs, edible fungi residues etc.)) produce through processing, its diameter is generally 6 ~ 8 millimeters, length is 4 ~ 5 times of its diameter, percentage of damage is less than 1.5% ~ 2.0%, dry basis moisture content is less than 10% ~ 15%, content of ashes is less than 1.5%, sulfur content and chlorinity are all less than 0.07%, and nitrogen content is less than 0.5%.Biomass fuel has following characteristics: caloric value greatly, is not corroded boiler, few, the ashes of atmosphere pollution, sanitation and hygiene, ash quarrel are not that machine potash fertilizer is recyclablely made profits, the reproducible energy.
Biomass fuel is the ideal fuels of the daily productive life of people thus, is the developing direction of environmental protection, sustainable energy; But there is following problem in current biomass stove:
1. be all middle and lower part, side or the bottom feed from burner hearth substantially at present, a charging and ash discharge public path often like this, can cause fuel not dryout only is just mixed and takes out of by ash, also may occur that ash is blocked by fuel, long-time row does not go out, take furnace cavity, hinder firepower (fire is below always at ashing), dust coking in burner (i.e. caking) after fuel and combustion, cause fuel to enter not go, dust can't get out, every fuel just must be ceased fire after several hours, to carrying out labor cleaning in biomass stove, time-consuming useless power, the significant obstacle that even becomes biomass stove lifeline (is that people often abandon using biomass stove because of the problem of coking in burner, and employing gas furnace), simultaneously because coking, bottom flame is directly roasted on the coke button on top, firepower is circulate upwards, cause coke button temperature more and more higher on the one hand, coking is tied more and more, flame is not smooth on the other hand, and firepower cannot be fed forward, and affects efficiency of combustion (efficiency of combustion refers to that the heat energy of being fully used after biomass fuel combustion accounts for the ratio of the whole heat energy that produce after biomass fuel combustion),
2. time-sharing type feeding, charging and ash discharge trouble, even affect continuous burning; Ash discharge trouble, automatic ash discharge continuously, needs human assistance ability ash discharge toward contact; Time-sharing type feeding does not have continuity, little when large when firepower, affects cooking effect.
3. there is no independently burner, whole burner hearth dust everywhere, fall in body of heater by the dust flying upward in burner hearth, is difficult to cleaning, can be cumulative; Combusting firepower is not prosperous, efficiency is not high.
Mineral particle fuel can be that coal is processed into granular fuel, and it burns and exists and the essentially identical problem of biomass granule fuel in current fuel cooking stove.
Summary of the invention
The feeding structure that the object of the invention is to overcome the above-mentioned deficiency of prior art and provide a kind of solid particle fuel cooking stove, burner makes fuel fully burn and to gasify, and efficiency of combustion is high; The whole flow process of solid particle fuel is smooth and easy, can coking, realize continuous feed fuels, and operating efficiency is high; Fuel can be dried and be not broken before burning, and environment protection smokeless is safe and reliable; Full automatic feed, has saved labour, also can make burning form good coupling with charging.
