Abstract
The utility model relates to an adjustable and continuous smokeless household stove for burning bituminous coal, a furnace of which is composed of a double-deck oven, and multilevel air supply is adopted. A colliery and a coal feeder with pulley wheels are arranged at the bottom of the stove. Bituminous coal or honeycomb briquet added in performs predrying, pyrolysis and surface local combustion in the colliery, and the coal feeder with pulley wheels can adjust the height of space of a lower gas combustion chamber, so as to control the reaction speed of pyrolysis and combustion of bituminous coal. Volatile ingredient in smoke is burnt out in the lower combustion chamber, a high-temperature zone and an upper combustion chamber, achieving sequential and continuous smokeless combustion of bituminous coal or honeycomb briquet in one direction.
Description
The utility model relates to a kind of domestic burners, continuously various bituminous coal of smokeless combustion and single fat gas coal type coal.
Realize the prior art in the bituminous coal non-smoke combustion technique field, " coal briquette for civillan use science and technology data compilation " discloses and a kind ofly added coal stove under continuous, this stove is with instead burning principle, only on common stove and accessory basis, increase a following coal mechanism, therefore when the bituminous coal pyrolysis and combustion, be difficult to the speed of separating out of volatilization composition in the control coal, the just more difficult control of bituminous coal thicker to gelatinous layer, that the volatilization composition is higher, and can not be by the upper-burning sequential combustion.A kind of down draught burning domestic burners is disclosed in the patent document (CN-85203854), this stove adopts unidirectional closed circuit combustion system, volatilization composition fully burning in closed-circuit system that bituminous coal is overflowed, but in combustion process, the necessary transposition of fire door coal and middle coal etc., so operation inconvenience, heat-energy losses is bigger.
In view of the problem that above-mentioned prior art exists, task of the present utility model is that design is a kind of can various bituminous coal of burning and single fat gas coal type coal, operates simple and easyly, can press the novel stove and accessory of the unidirectional smokeless combustion of upper-burning order continuously.
Feature of the present utility model is that burner hearth is made up of double-deck flue 1,2, furnace bottom has a colliery 5 and pulley coal feeder 8, constitute gas combustion chamber down between the upper surface of the coal in the colliery 5 and the fire bars, constitute between the upper surface of upper furnace coal and the furnace panel 9 and go up gas combustion chamber.Pulley coal feeder 8 adds new coal in the colliery 5, makes the coal face exceed 1～3 centimetre of colliery.It in the burner hearth high temperature coal seam of firing.The part heat heats up initiate coal by radiation and conduction etc., along with temperature rises, and new coal generation pyrolysis, destructive distillation and combustion reaction.The bigger volatilization composition of separating out from coal body fully mixes with the air that enters from main air door 12, and a part is fallen in primary combustion in following gas combustion chamber, unburnt volatilization composition rises to burner hearth, during through the high temperature coal body, mix again with the air that the hot blast that enters from the flue interlayer and adjustable pair of door of I and II 10,11 enter, and in the little gas combustion chamber that constitutes between the concave surface honeycomb briquette after the active combustion, residual fraction rises to the gas combustion chamber after-flame.Initiate coal needs 40 minutes most of cigarettes to eliminate approximately, and one time the coal amount is 1～2.The speed of pyrolytic reaction speed can be realized by the pulley step-less adjustment.Pressure pin 16 rises, and shortens the new distance (not smoldering with fire door is principle) that adds coal and fire bars 6, and reaction speed is just accelerated, otherwise just slows down.New coal is entered in the well to eliminate smoke immediately.The utility model adopts the one-level main air, pays wind for three grades and controls intake, realizes pressing the unidirectional burning of upper-burning order, promptly descend coal, on slag tap.This stove can adopt single No. 2 fat gas coals to add the moulded coal that 15～25% loess is made, and its specification is 125 * 50 millimeters of φ, 13 millimeters in 19 holes * φ; 100 * 60 millimeters of φ, 12 millimeters in 12 holes * φ, the also moulded coal of the bituminous coal of available other kinds and specification.Moulded coal can be bi-concave or single concave surface.Below be the technical parameter that records during with single No. 2 fat gas coal type coal combustions:
About the thermal efficiency 50%
Smoke density Lin Geman 0 degree (generally)
1～0 degree (operation is not proper)
About coal saving rate 30%
1.5～3.5 ℃/minute of the speed of getting angry
The utility model has overcome the shortcoming of known stove and accessory, has realized shaped coal of bituminous coal by the unidirectional continuous smokeless combustion of upper-burning order, have easy and simple to handle, advantage such as smoke effect is good.
Accompanying drawing is a kind of concrete structure profile of the present utility model.
The embodiment that represents below in conjunction with accompanying drawing elaborates to the utility model.
Furnace shell 3 adopts 0.8～1.2 millimeter iron sheet to process with mechanical or manual, and adjustable pair of air door of I and II 10,11 established in middle both sides, and a main air door 12 is established in the bottom.Colliery 5 is made by refractory liner outsourcing iron sheet, welds or is riveted on the furnace bottom.Well lid 7 can freely be opened, so that coal.It adopts double-deck card structure, can regulate three grades of sizes of paying wind 18.Pulley coal feeder 8 is made up of supporting plate 17, pressure pin 16, pulley 13, weight 15 and backstay.Set the position fulcrum on the supporting plate 17, can make the lotus root hole consistency from top to bottom of honeycomb briquette.15 balanced actions of weight, its weight can be fixed on it on arbitrary position of backstay 14 according to the practical operation needs approximately with the weight of pressure pin 16, supporting plate 17 and coal with equate.Double-deck flue is thin wall type, and wall thickness is 5～10 millimeters, and the pre-hot blast interlayer spacing of interior outer furnace 1,2 is 5～15 millimeters, leaves air inlet on the courage wall, and its quantity and position and I and II are adjustable, and pair air door 10,11 is corresponding.The total height of flue exceeds 3～5 centimetres for good than the total height of three lump coal.Outer furnace 1 back cut diameter is greater than inner furnace 2 lower port diameters, changes so that burn out the back at inner furnace.Gap will be reserved in the inner furnace lower end, and its number and position are corresponding with movable fire bars 6, can make it upwards free movable.Movable fire bars 6 is hinged with the stove plate, can establish 3～6.Heat-insulation layer adopts expanded perlite.
