Abstract
The utility model relates to an energy-saving coal stove, the cavity shape of a flue(2) is a tapered podetium with a big top and a small bottom; the upside of the flue(2) is opened with a controlling breathing hole(6) opening to the outside of a stove body(3), a combustion-supporting(7) with a rectangular solid is arranged above the controlling breathing hole(6) and the distance between the flue(2) centre can be adjusted by a bottom plane slide way; the flue inner wall with hollow air chute is provided with an accessorial vent(8). The thermal-decomposition and gasification speed can be effectively controlled by the combustion-supporting, so as to make the raw material in the stove thermal decomposed and gasified utmostly as a combustible gas under the oxygen-poor condition, and the firepower can be controlled by the combustion-supporting, at the same time the burning flame can be collected at the vessel bottom on the mouth, so as to reduce the thermal loss and improve the thermal efficiency.
Description
Affiliated technical field
The utility model belongs to a kind of home furnace, especially can both be used to burn the energy-conservation stove that bavin also can be used to burn coal.
Background technology
Existing have the people further to offer new combustion-supporting air inlet by the opening on stove below the grate on cooking stove as combustion air to burn the cooking stove of bavin or burning coal usually, in order to the abundant burning of air or steam reinforcement bavin coal.The appearance aqueous vapor makeup that discloses a kind of ring oven courage formula as the utility model patent that the patent No. is 96237536.5, name is called " energy-saving gasification flue " is put, be by to the flue water filling, and the gas making cylinder is sprayed with aqueous vaporization and on grate, and help fire burns, make the intensity of a fire fierce.But this gasification installation and flue are connected as a single entity, make the furnace construction complexity, and regulate the firepower size by water filling what or close into water and realize, extremely be difficult for grasping, can not really play regulating action, because the fixed position of air jet pipe has determined the distance of spout and flue.The consistency of this distance is what to be difficult to play to the regulating action of firepower, or fire is just big especially, and it is very little that Yi Guanshui, fire just become, and no intermediate link can be sayed; Also have, what existing firewood and coal range all adopted is straight tubular flue, and bavin or coal are in combustion process, and flame is straight formula earlier and rises, and a stringly just scatters suddenly to the flue top, makes firepower not too concentrated, causes thermal efficiency loss.And for the disclosing leakage of bavin ash or coal ash or even coal cinder slag, straight tubular flue still exists the defective of being inconvenient to leak slag.
Summary of the invention
The purpose of this utility model provides a kind of firepower of conveniently regulating that bavin or coal are fully burnt for the weak point that overcomes above-mentioned prior art existence just, and firepower is concentrated, and is convenient to leak the domestic energy-saving firewood and coal stove of slag.
The purpose of this utility model is achieved by the following technical solution.
The energy-conservation firewood and coal stove of these family expenses, the cavity shape of its flue are up-small and down-big taper cylinder; Offer a regulating the qi flowing in the channels hole that leads to the body of heater outside on flue top, be provided with that a cuboid combustion-supporting places on the regulating the qi flowing in the channels hole and can regulate distance with the flue center along the following baseplane slideway in regulating the qi flowing in the channels hole; The inboard wall of furnace that has the hollow ventilating duct offers auxiliary wind hole.
The conicity angles alpha of the inner chamber taper cylinder of flue is 1～12 °; The flue inner chamber also can be the alms bowl shape; Combustion-supporting is an airtight rectangular metal cavity, at the front upper of this cavity spray orifice that to be provided with two diameters be 0.2～0.8mm; Offer the air-permeating hole of air being introduced the hollow air channel in the bottom of flue; The chute board of bottom, regulating the qi flowing in the channels hole can put in flue and stretch out one section of body of heater.
When bavin or coal place the flue burning, the combustion-supporting cavity is seated on the slideway of bottom, regulating the qi flowing in the channels hole, and place near flue as far as possible, when treating that the furnace temperature heating makes the combustion-supporting temperature be elevated to a certain degree, combustion-supporting is put in the water, in the negative pressure nature inspiration container that water is produced in the combustion-supporting cavity, combustion-supporting is placed in the regulating the qi flowing in the channels hole again, just produced jet by spraying the formation combustion-supporting gas in the spray orifice.By regulating the distance at combustion-supporting and flue center, can control the size of firepower.Burned flame is upwards concentrated the container bottom that converges on the fire door along up-small and down-big flue, and the thermal efficiency is improved greatly.
Further specify the utility model below in conjunction with drawings and Examples
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is fire door partial structurtes schematic diagrames,
Fig. 3 is the combustion-supporting schematic diagram.
The specific embodiment
Present embodiment flue 2 is up-small and down-big conical cylinder, and tapering α is 4 °, and annular fan housing 1 places body of heater 3 tops, and grate 4 is located at flue 2 bottoms, and stove air port 5 is located at furnace base 9 tops under grate 4.Offering a through hole that leads to body of heater 3 outsides on flue 2 tops is regulating the qi flowing in the channels hole 6, combustion-supporting 7 is the airtight rectangular cavities that the employing 2mm thick sheet metal assembly welding that is independent of outside the body of heater forms, have the spray orifice 10 of two 0.4mm in the rectangular cavities front upper, at handle 12 of the back side of rectangular cavities welding, pass combustion-supporting 7 to make things convenient for people's holds.This combustion-supporting 7 places on the regulating the qi flowing in the channels hole 6 and can move along the chute board 11 of going to the bottom in regulating the qi flowing in the channels hole 6, reaches the purpose of regulating combustion-supporting 7 and flue 2 centre distances.And chute board 11 can be designed to put in 2 one sections of flues and stretch out 3 one sections of bodies of heater, with the lengthening of assurance adjustable range, thus the size that can accomplish stepless adjustment firepower.Flue 2 is the metal structure of a hollow, offers the auxiliary wind hole 8 of five rows within it on the wall, and the air-permeating hole 13 in hollow air channel is opened in the bottom of flue.Thermal insulation layer 14 is used for insulation and heat-blocking action.
The utlity model has following advantage: the pyrolytic gasification speed that can effectively control raw material in the stove, increase ventilation and pass through the jet distance of control, make in the stove raw material to greatest extent under anoxia condition pyrolytic gasification become fuel gas, and can control the firepower size effectively by combustion-supporting, combustion flame can be concentrated the container bottom that gathers on fire door simultaneously, reduce thermal losses, improved the thermal efficiency.
