Specific embodiment
In order to make the foregoing objectives, features and advantages of the present invention clearer and more comprehensible, below in conjunction with the accompanying drawings to the present invention Specific embodiment be described in detail.Many details are elaborated in the following description in order to fully understand this hair It is bright.But the invention can be embodied in many other ways as described herein, those skilled in the art can be not Similar improvement is done in the case of violating intension of the present invention, therefore the present invention is not limited by following public specific embodiment.
Unless otherwise defined, all of technologies and scientific terms used here by the article is with belonging to technical field of the invention The normally understood meaning of technical staff is identical.Term used in the description of the invention herein is intended merely to description tool The purpose of the embodiment of body, it is not intended that in the limitation present invention.Term as used herein "and/or" includes one or more The arbitrary and all combination of relevant Listed Items.
As shown in Figure 1, a kind of heating-cooking integral biomass combustion furnace, the combustion furnace include hopper 1, blanking channel 2, Combustion chamber main body 3, smoke channel box 4, water jacket, gasification circle 5, upper furnace grate 6, lower fire grate 7 and ash accepting box 8;The hopper 1 is arranged on described 2 upper end of blanking channel;The blanking channel 2 is connected between the hopper 1 and combustion chamber main body 3, and hopper 1 passes through blanking channel Inside the 2 connection combustion chamber main bodys 3;The combustion chamber main body 3 is connected to 2 end of blanking channel;The smoke channel box 4 is logical It crosses smoke discharging pipe and connects the combustion chamber main body 3;The water jacket is arranged on 4 outside of the combustion chamber main body 3 and smoke channel box, burning Water guide pipeline is equipped between the water jacket in 4 outside of room main body 3 and smoke channel box;The gasification circle 5 is arranged in the combustion chamber main body 3 Portion, gasification circle 5 are located at 6 top of upper furnace grate;The upper furnace grate 6 is arranged on inside the combustion chamber main body 3;The lower fire grate 7 are arranged on 6 lower section of upper furnace grate;The ash accepting box 8 is arranged on 7 lower section of lower fire grate.
In one embodiment of heating-cooking integral biomass combustion furnace, it is empty that 6 top of upper furnace grate forms the first burning Between 9, the second combustion space 10 is formed between the upper furnace grate 6 and lower fire grate 7.The master that upper furnace grate 6 burns as biological particles Position is wanted, particulate material drops down onto the first combustion space 9 by blanking channel 2 out of hopper 1 and burns, and lower fire grate 7 makes upper furnace grate 6 On material burning after uncombusted part fall within and burn away on lower fire grate 7.
In one embodiment of heating-cooking integral biomass combustion furnace, the water jacket is equipped with the first water jacket 11 and the second water Set 12, first water jacket 11 are arranged on 3 outside of the combustion chamber main body, and 11 side of the first water jacket is equipped with water inlet 13, and first 11 lower end of water jacket is equipped with drain valve 14 and explosion-proof valve 15.After the heat generated in combustion furnace burner hearth is absorbed by the water in water jacket, Hydraulic pressure rises.Drain valve 14 is used to discharge the water in water jacket, and stove body temperature excess pressure is excessive when explosion-proof valve 15 prevents from burning And it explodes.Second water jacket, 12 upper end is equipped with water outlet 16, is connected between the water outlet 16 and the water inlet 13 There is radiator.Hot water in water jacket enters heat dissipation equipment from water outlet 16.
In one embodiment of heating-cooking integral biomass combustion furnace, 4 upper end of smoke channel box is connected with fume discharge connector 17, Zigzag type channel is formed with inside smoke channel box 4.Fume discharge connector 17 is for cigarette receiving cylinder or is passed through heated kang.
In one embodiment of heating-cooking integral biomass combustion furnace, 8 outside of ash accepting box is equipped with ventilation base 18. Ventilation base 18 collects ashes for air inlet and Boiler pressure control.
In one embodiment of heating-cooking integral biomass combustion furnace, 3 upper end of combustion chamber main body is equipped with stove circle 19. By gasification circle 5, the abundant after-flame under the action of high temperature, sufficient oxygen is burnt unburned sufficient flue gas by stove circle 19 Water cooking.
Heated kang is connected with fume discharge connector 17 of the present invention, water inlet 13, water outlet 16 illustrate for connecting heating equipment:
Biomass fuel will be filled in hopper 1, under the effect of gravity, fuel flows into upper fire grate by blanking channel 2, flows to Stop after a certain amount of, fuel is lighted in lower fire grate bottom by the ventilation opening of ventilation base 18, enclosed ventilation mouth covers stove circle 19, after fuel combustion is got up, with the fuel after-flame in upper fire grate, the fuel in hopper 1 can be automatically flowed on lower fire grate, directly Until 1 fuel whole after-flame of hopper.Since fume discharge connector 17 connects heated kang flue, under natural wind effect, combustion chamber main body 3 And subatmospheric negative pressure is generated in smoke channel box 4, flue gas can be from the discharge of smoke evacuation path, because smoke path lengthens, and flue dust can be 4 inner wall of smoke channel box is attached in smoke channel box 4 in flow process.The complete ashes that burn can drop into ash accepting box 8 by lower fire grate Interior, not completely burned off particle can be rested on fire grate and be fallen into ash accepting box 8 after completely burned off.It cooks or burns if needed The demand of water can take away the bell in stove circle 19, and kettle or pot are placed directly in stove circle 19, suitably adjust wind Amount controls burning velocity.After being absorbed with the heat generated in burner hearth by the water in water jacket, hydraulic pressure rises, therefore hot water meeting Enter radiator from water outlet 16, the cold water in radiator is pressed into water inlet 13 under the pressure of hot water, forms cycle Heat in combustion chamber main body 3 by recirculated water in the radiator of heating and ventilating equipment is circulated and plays the effect of heat dissipation by flow.This Small, light-weight, convenient transportation when invention uses saves space, and main part carries water jacket, can connect heating and ventilating equipment, fires Quick heating in burner hearth during burning, water jacket endothermic effect are good.Fume discharge connector 17 can cigarette receiving cylinder, can also be passed through heated kang, pass through Flue duct design The heat in combustion gas can be fully absorbed, the thermal efficiency is high, and chimney tail flue gas naked eyes are invisible, and flue gas content meets national mark Standard, without electrical control, automatic blanking, heating while, can be also used for cooking, easy to operate, stablize, energy conservation and environmental protection.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality It applies all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited In contradiction, it is all considered to be the range of this specification record.
Embodiment described above only expresses the several embodiments of the present invention, and description is more specific and detailed, but simultaneously It cannot therefore be construed as limiting the scope of the patent.It should be pointed out that those of ordinary skill in the art are come It says, without departing from the inventive concept of the premise, various modifications and improvements can be made, these belong to the protection of the present invention Range.Therefore, the protection domain of patent of the present invention should be determined by the appended claims.
