The screw rod of lift grate revolves screw thread about being.
The utility model adopts by forming body of heater by end inner core and urceolus of the no end, establish air inlet one time in bottom of furnace body, establish the lift grate in the burner hearth, upper of furnace body is established the secondary air mouth, the technical scheme of double-deck firestopping ring is established at the body of heater top, it is not high because of the thermal efficiency to have overcome existing biomass half-gasification oven, and heat energy utilization is insufficient, will repeatedly add defectives such as biological material in the cooking process.
The beneficial effect that the utility model is produced compared to existing technology:
(I) be provided with two air inlets and be combined with end inner core and urceolus of the no end and divide air inlet and secondary air mouth in the body of heater, adjusting has the intake of an air inlet on the end inner core to make to reach half vaporized state in the stove, burning once more after the oxygen that the fuel gas that living beings produce makes progress with the secondary air mouth is come in mixes, realized being gasified totally and burn of living beings, made the utilization of heat energy reach optimum state;
(II) double-deck firestopping ring is established at the body of heater top, the size of the size of interior firestopping ring passage and body of heater top cover basal pot ring is equipped with, the high-temperature flue gas that makes mixed combustion is by staggering mutually and during the mazy firestopping ring passage of full of twists and turns one-tenth, naturally increased the time of staying of high-temperature flue gas, interior firestopping ring passage is nearest from body of heater top cover basal pot ring, surplus cigarette high temperature heat is tried to be the first absorbed, both reduced exhaust gas temperature, significantly improved the thermal efficiency again by the bottom of a pan;
(III) establish the lift grate in the burner hearth, can disposablely put sufficient biomass fuel, the size of the size of interior firestopping ring passage and body of heater top cover basal pot ring is equipped with, increased the seal of burner hearth, thereby eliminated the burner hearth top defective that high heat is slipped away from breach because of charge door makes, realized zero loss of the thermal efficiency;
(IV) the utility model structure is extremely simple, and is easy to manufacture, operate very simple, safe and reliable, with low cost, non-environmental-pollution, the scope of application is wide and be convenient to penetration and promotion.
The utility model is fit to half-gasification oven, the kitchen range of various use bio-fuels.
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
Description of drawings
Fig. 1 is a front view of the present utility model.
Fig. 2 is Fig. 1 vertical view.
Among the figure: 1, inner core, 2, urceolus, 3, air inlets, 4, grate, 5, the secondary air mouth, 6, double-deck firestopping ring, 7, chimney, 8, interior firestopping ring passage, 9, outer firestopping ring passage, 10, the body of heater top cover, 11, basal pot ring.
The specific embodiment
Referring to accompanying drawing, a kind of biomass half-gasification oven, it comprises by forming body of heater by end inner core 1 and urceolus of the no end 2, lift grate 4 is set in the burner hearth of the furnace body, about being set to, the screw rod of lift grate 4 revolves screw thread, bottom of furnace body is provided with air inlet 3 one time, this air inlet 3 passes on the inner tube wall that is installed in end inner core 1 bottom from urceolus of the no end 2, upper of furnace body is established secondary air mouth 5, this secondary air mouth 5 directly evenly is laid on the inner tube wall on end inner core 1 top by two to five rows, the secondary air mouth 5 of present embodiment is that two rows evenly are laid on the inner tube wall, the body of heater top is established double-deck firestopping ring 6 and is communicated with the chimney 7 of firestopping ring passage, the firestopping ring passage comprises interior firestopping ring passage 8, outer firestopping ring passage 9, interior firestopping ring passage 8 staggers mutually with outer firestopping ring passage 9 and full of twists and turnsly is arranged to mazy firestopping ring passage, firestopping ring passage 8 is located at body of heater top cover 10 places in it, and the size of the size of interior firestopping ring passage 8 and body of heater top cover 10 basal pot rings 11 is equipped with.
