Described pre-mixing type combustion apapratus, inboard, lower end at described shading ring is provided with step, the outside, upper end at described premixer shell is provided with step, by cooperating of shading ring lower end step and premixer's shell upper end step, shading ring and premixer are closely linked together, be provided with step in the outside, described shading ring upper end, the described inboard, fire ring lower end of protecting is provided with step, by the shading ring upper end step with protect cooperating shading ring and protect fire ring and closely linking together of fire ring lower end step.
Described pre-mixing type combustion apapratus, the described first honeycomb pottery shard diameter is identical with second honeycomb pottery shard.
Described pre-mixing type combustion apapratus, described shading ring diameter is 70-145mm, premixer's height is 30-40mm, the spacing of first honeycomb pottery shard and second honeycomb pottery shard is 20-30mm, the diameter of first honeycomb pottery shard and the second nest pottery sheet is 60-135mm, thickness is 5-10mm, and the diameter in the hole on first honeycomb pottery shard and second honeycomb pottery shard is 2-3mm.
Described pre-mixing type combustion apapratus, the described second honeycomb pottery shard diameter is greater than the first honeycomb pottery shard diameter.
Operation principle of the present utility model is owing to increased the premixer, when combustion gas and air by air blast from the air distribution pipeline in mouth at the bottom of the basin type shell enters the pre-mixing chamber of basin type shell, after fully mixing, sieved uniformly by honeycomb pottery shard, owing to realized premix, fuel gas buring is abundant, has realized energy-conservation thereby improved the thermal efficiency.
Description of drawings
Fig. 1 is a longitudinal profile decomposing schematic representation of the present utility model.
The specific embodiment
As shown in Figure 1, premixer's shell 1 is the basin type, its end mouth is connected with tapered sleeve 6, tapered sleeve 6 is connected with gaseous mixture standpipe 7, blower fan is transported to pre-mixing gas combustion in the basin type burner housing 1 by gaseous mixture standpipe 7, be provided with first honeycomb pottery shard 2 in the upper edge ring week of basin type burner housing 1, as shown in Figure 2, basin type burner housing 1 back cut diameter is between 60mm-135mm, honeycomb pottery shard 2 diameters also are 60mm-135mm., thick 5-10mm, its aperture is 2-3mm., distance is 30-40mm between the lower surface of honeycomb pottery shard 2 and the basin shape outer casing bottom.
Shading ring 3 is an annular, diameter 70mm-145mm, and high 33mm is arranged on the basin type burner housing 1, and its end mouth closely links to each other with basin type burner housing 1, presses tight first honeycomb pottery shard 2.And distance be 20-30mm between shading ring 3 top and second honeycomb pottery shard 4 that is provided with second honeycomb pottery shard, 4, the first honeycomb pottery shards 2 suitable for reading following, and the formation surge chamber.The diameter of second honeycomb pottery shard 4 can be identical with the diameter of first honeycomb pottery shard 2, also can be greater than the diameter of first honeycomb pottery shard 2.
Protect fire ring 5 and be arranged on second honeycomb pottery shard 4, with 3 suitable for reading joining of shading ring, protecting fire ring 5 diameters is 70mm-145mm, high 11mm.
Connect between the fire ring 5 closely in order to make premixer's shell 1, shading ring 3 and to protect, inboard, lower end at shading ring 3 is provided with step, the outside, upper end at premixer's shell 1 is provided with step, by cooperating of shading ring 3 lower end steps and premixer's shell 1 upper end step, shading ring 3 and premixer's shell 1 are closely linked together, be provided with step in the outside, shading ring 3 upper ends, protect inboard, fire ring 5 lower end and be provided with step, by shading ring 3 upper end step with protect fire ring 5 lower end steps cooperate with shading ring 3 with protect fire ring 5 and closely link together.
Because this kind burner makes the fuel in certain proportion air distribution, realizes repeatedly premix, excess air coefficient is slightly larger than 1, and fuel gas buring is abundant, has given play to potential, so thermal efficiency height, exhaust emissions is lower than GB.
Because the combusting device stove burner of this burner apparatus adopts special double-deck honeycomb pottery shard and stove basin to form the gentle plenum chamber of a pre-mixing chamber, not only make the abundant premix of combustion gas, simultaneously more because cushioning effect makes the mixed airflow of high-pressure gas and wind form current stabilization, from the ejection of the second pottery sheet air flue, owing to formed current stabilization, fuel gas injection speed reduces, thereby controlled the speed of this honeycomb pottery shard single flow burning, flame becomes surely, and it is more abundant to burn, brought into play potential, thereby realized energy-conservation.
Owing to take double-deck honeycomb pottery shard device, after high-pressure gas and wind enter the stove basin, through a plurality of isometrical ducts of the first pottery sheet combustion gas was sieved as sieve, both reduced speed, be uniformly dispersed again, and solved and used individual layer pottery sheet when fuel gas high-speed sprays, to differ owing to the skewness and the flow velocity of combustion gas on the pottery sheet, during burning pottery sheet surface temperature variant cause the pottery sheet be heated uneven occur burning red, grill thoroughly, not only burn out the pottery sheet, and tempering occurs, thereby problem such as cause danger.
Owing to take double-deck honeycomb pottery shard isolation technology, flame can produce the infrared ray combustion efficiency when surface combustion, generate Chinese red flame, flame high-temperature region temperature can reach 1250 degree, the efficient height saves time, and economizes gas, exhaust emissions reduces greatly during burning, not only energy-conservation reaching more than 35%, the discharging of CO and NO does not simultaneously exceed standard, and has realized environmental protection and energy saving.
The premixed gas combustion burner device of the double-deck honeycomb pottery shard of the utility model adopts combined type to install, and is used for kilns such as industrial porcelain kiln, is applicable to hotel, hotel, army, universities and colleges dining room simultaneously.
More than be preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model when the function that is produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
