Heat accumulating burner capable of the present invention, the shape of wherein said cold wind wind cover and the shape of the fuel nozzle in it adapt.
Heat accumulating burner capable of the present invention, wherein said cold wind wind cover is fixedly connected with body of heater through flange, and the outer end of cold wind wind cover is provided with interior edge, and weld with fuel nozzle on interior edge, and cool air hose is welded on cold wind wind and puts.
The present invention also provides a kind of heat storage type combustion method; Combustion-supporting hot-air and fuel are got in the body of heater by separately passage respectively and mix after-combustion; No-fuel-switch ground is without interruption in stove; Combustion-supporting hot-air is an alternate supplies, and the combustion-supporting cold wind that wherein is lower than the required combustion air volume 10% of fuel combustion supporting is without interruption, and combustion-supporting cold wind gets in the body of heater fuel mix after-combustion of failing completing combustion with mixed combustion in advance.
Heat storage type combustion method of the present invention, wherein said combustion-supporting cold wind gets in the body of heater from the outside of fuel.
Heat accumulating burner capable of the present invention and method thereof; The combustion-supporting cold wind that is lower than the required combustion air volume 10% of fuel combustion supporting is without interruption; Combustion-supporting cold wind gets in the body of heater fuel mix after-combustion of failing completing combustion with mixed combustion in advance, has improved flame rigidity, quickens to be heated the firing rate of material; Effectively reduced the concentration of nitrogen oxide in the flue gas, environment protecting significantly promotes.
Description of drawings
Fig. 1 looks cutaway view for the master of heat accumulating burner capable of the present invention;
Fig. 2 is the vertical view cutaway drawing of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2; Heat accumulating burner capable of the present invention; Comprise body of heater 1; Body of heater 1 be provided with the fuel nozzle 2 that sprays into fuel be connected with body of heater 1 in stove, be blown into combustion air and take out and draw the left and right regenerator 3,4 that flue gas is the heat storage accumulation of heat, cold wind wind cover 5 is equipped with in the outside of fuel nozzle 2, has formation cold wind air channel, gap 21 between cold wind wind cover 5 and the fuel nozzle 2; Cold wind wind cover 5 is fixedly connected with body of heater 1 through the flange (not shown), and the inner in cold wind air channel 21 communicates with body of heater 1.Edge 51 in the outer end of cold wind wind cover 5 is provided with, interior edge 51 and fuel nozzle 2 are welded the outer end sealing in cold wind air channel 21 or are adopted other sealing means, weld fixedly cool air hose 6 on the cold wind wind cover 5, and cool air hose 6 overlaps 5 with cold wind wind and communicates.The shape of cold wind wind cover 5 and the shape of the fuel nozzle 2 in it adapt.
Heat storage type combustion method of the present invention; Fuel gets into body of heater 1 by fuel nozzle 2; No-fuel-switch ground is without interruption in stove; Combustion-supporting hot-air gets in the body of heater 1 through left and right regenerator 3,4 alternate supplies, and fuel and combustion-supporting hot-air mix after-combustion in body of heater 1, and the combustion-supporting cold wind that is lower than the required combustion air volume 10% of fuel combustion supporting is without interruption through cool air hose 6; Combustion-supporting cold wind gets in the bodies of heater 1 from cold wind wind cover 5 and cold wind air channel 21 between the fuel nozzle 2, in body of heater 1 and the fuel mix after-combustion of failing completing combustion of mixed combustion in advance.Combustion-supporting cold wind gets in the body of heater 1 from the outside of fuel, and more abundant with fuel mix, it is more abundant to burn.
Heat accumulating burner capable of the present invention and method have following advantage:
1, improves flame rigidity, quickened to be heated the firing rate of material;
2, fuel combustion is more abundant, effectively reduces the concentration of nitrogen oxide in the flue gas, and the discharge capacity of NOx also is reduced in the discharging scope of national requirements, and environment protecting significantly promotes, and has improved environmental benefit widely;
3, fuel combustion is more abundant, and energy-saving effect significantly promotes, the about 30-70% of energy savings:
4, reduce oxidization burning loss, for being the production of product with the metal, its oxidization burning loss can reduce 20% on existing basis.
5,, therefore thoroughly solved the existing aborning hidden danger of existing heat accumulating type high-temperature air burning method and apparatus because cold wind wind cover has been introduced the combustion air without interruption that is lower than the required combustion air volume 10% of fuel combustion supporting.
