Technical field
The utility model relates to a kind of biomass fuel cooking stove, belongs to stove or kitchen range technical field.
Background technology
Biomass fuel is a kind of New-type fuel that rose in recent years.Biomass fuel belongs to bioenergy, is to be the energy of carrier with living beings, mainly refers to fuel wood, farm-forestry crop, crop residues, animal wastes and house refuse etc.Because biomass fuel will consume CO2 in process of production, just in time offset the CO2 that produces in its combustion process.Burning-used biologic mass fuel, not only SO2 discharging is few, the NOx discharging is low, has the characteristics of " CO2 zero-emission ", and biomass fuel belongs to renewable resource, therefore is subjected to more and more personages' attention.Different with coal, the volatile ingredient content of biomass fuel is than higher, and traditional coal stove should not directly be used for firing biomass fuel, otherwise can produce the incomplete combustion phenomenon.Even at the custom-designed stove and accessory of biomass fuel, also can produce bad phenomenon such as incomplete combustion owing to design is improper, influence the application of biomass energy.Shortcomings such as present existing biomass fuel utilizes equipment ubiquity complex structure, efficiency of utilization is on the low side, the effect of banking up a fire is bad.Therefore, be necessary for the biomass fuel design and develop a kind of better burner, could realize the efficient utilization of the efficient burning and the heat energy thereof of biomass fuel.
Summary of the invention
The folded combustion that the purpose of this utility model is the defective that overcomes prior art, a kind of sufficient combustion is provided, the heat energy utilization rate the is high formula biomass fuel cooking stove that liquidates.
The technical scheme that addresses the above problem is:
A kind of folded combustion formula biomass fuel cooking stove that liquidates, it comprises body of heater 1, fire grate 9, tile 10, grey chamber 11, charge door 12 and flue 8; Described body of heater is a sandwich, and filling fire resisting material constitutes the heat-insulation layer 2 of body of heater in the interlayer; Inboard wall of furnace body is provided with tile; The body of heater bottom is a fire grate 9, is grey chamber 11 under the fire grate, is the primary zone between fire grate and the tile; Body of heater one side on top, combustion chamber is provided with charge door 12; In upper of furnace body after burner is set, after burner is a cylinder shape, and ring constitutes secondary combustion chamber 15 in it, uniform air vent 6 on the internal ring wall face, and the top and bottom sealing of ring tube constitutes secondary air chamber 13, and the secondary air chamber is communicated with secondary wind inleting tube 4.
The above-mentioned folded combustion formula biomass fuel cooking stove that liquidates, at the center of body of heater center blast pipe 5 is set, described center blast pipe lower nozzle passes the primary zone, stretches out outside the body of heater, and upper orifice is positioned at secondary combustion chamber, evenly is provided with air vent on the top of center blast pipe.
The above-mentioned folded combustion formula biomass fuel cooking stove that liquidates, described secondary wind inleting tube is provided with along the body of heater both sides, and is embedded between the insulating layer of furnace body, and its bottom air inlet mouth communicates with atmosphere, upper end air outlet and the connection of secondary air chamber.
The above-mentioned folded combustion formula biomass fuel cooking stove that liquidates is provided with between described secondary combustion chamber and the last fire door at interval, and chamber of Gou Chenging and chimney communicate thus, and close floss hole place is provided with a grade pyrosphere at chamber.
The above-mentioned folded combustion formula biomass fuel cooking stove that liquidates, described grey chamber is provided with grey chamber door, and described charge door is provided with gallery ports.
The utility model is overcoming the defective that existing biomass combustion stove burning is insufficient, the heat energy utilization rate is low, on the basis of an air intake, set up secondary air system circumferential and the folded combustion formula in center, the high-temperature flue gas that has fuel gas that is come out in the combustion chamber is fully burned.This stove adopts closedly adds the feed bin design, in use, makes and is interrupted the fuel that replenishes obtains preheating and drying in adding feed bin, has improved half gasification, and combustion effect, has reduced oke exhaust blackness.Adopt good body of heater of insulation and airtight good grey chamber air inlet, can make stove and accessory have the good effect of banking up a fire.Therefore the utlity model has the characteristics that programming rate is fast, intensity of fire big, burning is complete, the thermal efficiency is high.
Description of drawings
Fig. 1 is the utility model structural representation profile;
Each mark is as follows among the figure: 1. body of heater, 2. heat-insulation layer, 3. go up fire door, 4. secondary wind inleting tube, 5. center blast pipe, 6. air vent, 7. stove fire lid, 8. flue, 9. fire grate, 10. tile, grey chambers 11., 12. charge doors, secondary air chambers 13., 14. firestopping rings, 15. secondary combustion chambers.
The specific embodiment
Referring to accompanying drawing 1, the utility model is the improvement on ordinary student material Heating stove basis, comprises body of heater 1, burner hearth, fire grate 9, tile 10, grey chamber 11, charge door 12 and flue 8 in the formation, and body of heater is a sandwich, the inner filling fire resisting material of interlayer constitutes insulating layer of furnace body 2.Described burner hearth is positioned at the body of heater centre, and the burner hearth inboard is provided with tile, and the tile bottom is a fire grate, and the fire grate bottom is grey chamber, inlet air plenum of grey chamber double as, and grey chamber to be opened/closed door is set.Constitute first combustion chamber between this stove fire grate top and the tile, the middle and upper part of first combustion chamber has one to the charge door of burner hearth for fuel, between charge door and the burner hearth for adding feed bin, be provided with one to the center of burner hearth air feed blast pipe 5 in the burner hearth centre, its air inlet runs through grey chamber downwards, communicate with atmosphere, blast pipe upper end in center leads directly to secondary combustion chamber 15, and along the tube wall circumferential interval air vent is set.In the furnace body inside heat-insulation layer, secondary wind inleting tube 4 is set, its bottom air inlet mouth communicates with atmosphere, and the upper end air outlet is communicated with secondary air chamber 13, and circumferential interval is provided with passage in the secondary air indoor, and it is circumferentially combustion-supporting to form secondary wind.Be the flue cavity between following fire door 16 and the last fire door 3, near flue 8 places the firestopping ring 14 that can regulate and move be set, be provided with the stove fire lid 7 that to bank up a fire at fire door 3 places at the flue cavity.
During use, with the indoor fuel such as stalk forming piece of loose stalk ignition combustion, after treating that stove is on fire, add virgin material, wait fuel burn prosperous after, close grey chamber air inlet, biomass massive fuel is burnt in burner hearth, the high-temperature flue gas that contains fuel gas that forms rises to secondary combustion chamber, circumferentially fires combustion-supporting being fully burned with folding through top, has overcome in the past owing to center flue gas fast rise can not combine phenomenons such as the smoke evacuation, the carbon monoxide that cause exceed standard with secondary wind.When the fuel shortage in the burner hearth, can be from charge door postcombustion to the combustion chamber.After in adding feed bin, filling up biomass massive fuel, close gallery ports.Because fuel obtains preheating and drying in adding feed bin, improved half gasification result, has reduced oke exhaust blackness.When banking up a fire, will add in the feed bin fuel after the preheating and add in the burner hearth, and close grey chamber air inlet and get final product.
Combustion space of the present utility model, grate area and profile can be designed to different specifications and models according to the heating area thermic load.
The utility model is simple in structure, easy to operate, can realize the efficient and clean burning of biomass fuel, is specially adapted to cities and towns, cottar family and other small-scale cooking demands.
