Abstract

The utility model relates to an upper burning smokeless energy saving stove. The difference between the upper burning smokeless energy saving stove and the ordinary coal stove lies in that more than one secondary wind pipes of which the cross section is semicircular are uniformly arranged on the outside circumference of a stove tile. The secondary wind pipes preheat wind which comes from a lower stove cavity through the outer surface of the stove tile and send the wind to an annular chamber on the circumference of a stove nozzle. The wind from the annular chamber goes to an upper stove cavity through a secondary wind pipe so as to help combustible gas which is not fully burned in a combustion stove. For the reasonable match of a first wind and a secondary wind, the combustion is complete, the fire supply is quick, the heat preservation performance is good, and the discharged smoke gas after the combustion has few harmful components. The utility model is suitable for the use of households and cooking service industries.

Description

The upper-burning smoke-less energy-saving stove

The utility model is a kind of upper-burning smoke-less energy-saving stove for bituminous coal coal briquette or the smokeless combustion of brown coal coal briquette, belongs to life use stove tool technical field.

Be used to burn the stove and accessory of coal briquette at present, can only be used to burn anchracite ball, directly bituminous coal coal briquette or brown coal coal briquette, if with existing stove and accessory bituminous coal or brown coal coal briquette then fire door can be emerged a large amount of black smokes, cause environmental pollution, be detrimental to health.

Task of the present utility model is in order to overcome that existing stove and accessory is not suitable for burning the shortcoming of bituminous coal or brown coal and a kind of upper-burning smoke-less energy-saving stove of developing is used to burn bituminous coal, brown coal, and especially Indonesia 1 ^#～5 ^#Brown coal reach energy-conservation, improve combustion rate, reduce pernicious gas to the air-polluting purpose.

Structure of the present utility model is as shown in Figure 1: by furnace shell (1), stone or metal plate for standing a stove on as a precaution against fire (2), secondary air hole (3), fire-collection ring and pot frame (4), secondary air channel (6), heat-insulation layer (7), tile (8), adjustable fire door (9), fire grate (10), furnace bottom (11) constitute; Fire grate (10) is divided into upper and lower two parts with burner hearth, and the comb bottom is divided into dust stratification slag and aeration portion, and comb top is divided into coaling ball and combustion space; Being evenly distributed with one around tile (8) outside is the secondary air channel (6) of half garden shape with upper section, its upper end open is in ring casing (5), and be communicated with upper furnace by overfiren air port (3), the lower end is supported on fire grate, and be opened on the fire grate hole, tile (8) is the hollow truncated cone, and the lower end is bearing on the fire grate; Furnace bottom (11) is a bowl-type, to increase heat radiation, lower hearth has adjustable fire door (9), can regulate air quantity, secondary air hole (9) is opened in tile (8) upper end, quantity is 6～20, the aperture is 10～40mm, evenly distribute at distance fire door 10～40mm place, the tile of the truncated cone (8) awl base angle is 70 °～85 °, tile (8) insulation layer (7), secondary air channel (6) and furnace shell (1) coat, and heat-insulation layer (7) is filled into secondary air channel (6) lower edge, stone or metal plate for standing a stove on as a precaution against fire (2) and heat-insulation layer (7) and furnace shell (1), form an annular space between the tile (8), be ring casing (5), can be for being flowed interior, and enter upper furnace from secondary air hole (3) by the secondary wind of tile preheating, with combustion-supporting unburned fuel gas completely; Thermal loop is an arch design, plays heat build-up, improves the heat radiation effect, has pot frame on the thermal loop so that lay stove and accessory etc.

Embodiment of the present utility model:

Furnace shell (1), stone or metal plate for standing a stove on as a precaution against fire (2), fire-collection ring and pot frame (4), fire grate (10), all available ferrous materials of adjustable fire door (9).Heat-insulation layer (7) is used mineral fibres.

The prescription of tile material is: refractory cement: fire sand: hard wheat cake wood=10～50%: 10～50%: 0～50% (percentage by weight).

The proportioning of furnace hearth material is a refractory cement: hard wheat cake wood: perlite=10～50%: 10～50%: 0～50% (percentage by weight).

Hard wheat cake wood is the natural mineral fiber of main component for a kind of oxide with calcium, magnesium, silicon.

Description of drawings:

Fig. 1 is the half sectional view of upper-burning smoke-less energy-saving stove

Fig. 2 is the A-A sectional view of upper-burning smoke-less energy-saving stove

Number among the figure: 1. furnace shell; 2. stone or metal plate for standing a stove on as a precaution against fire; 3. secondary air hole; Fire-collection ring and the pot frame; 5. ring casing; 6. secondary air channel; 7. heat-insulation layer; 8. tile; 9. but air register; 10. fire grate; 11. furnace bottom, 12. burner hearths.

The utility model has the advantages that the saving furnace burning is filled because the reasonable coordination of a Secondary Air is arranged Divide, quick combustion, good heat insulating, the heat utilization rate height is harmful in the eliminating flue gas after the burning Divide, be fit to family and cooking service industry and use.
