Description
Technical field
The utility model relates to a kind of burner, particularly a kind of heat accumulating burner capable.
Background technology
The patent No. is that 02116514.9 utility model patent discloses a kind of heat accumulating burner capable; This device comprises body of heater, and body of heater is provided with the fuel nozzle that sprays into fuel and in stove, is blown into combustion air and draws the regenerator that flue gas is the heat storage accumulation of heat to take out with two that are connected with body of heater.The defective of this device is that the combustion flame rigidity is not enough, even can cause fuel nozzle flame to move swiftly, can not smooth combustion, and amount of nitrogen oxides is high in the flue gas, and it is slow to be heated the material firing rate.
The utility model content
The technical problem that the utility model will solve provides a kind of heat accumulating burner capable that improves flame rigidity, reduces amount of nitrogen oxides in the flue gas.
For solving the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of heat accumulating burner capable; Comprise body of heater; Body of heater is provided with at least one fuel nozzle that sprays into fuel and in stove, is blown into combustion air and draws the regenerator that flue gas is the heat storage accumulation of heat to take out with at least two that are connected with body of heater, and cold wind wind cover is equipped with in the outside of wherein said fuel nozzle, has the gap between cold wind wind cover and the fuel nozzle and forms the cold wind air channel; Cold wind wind puts fixedly cool air hose; Cool air hose communicates with cold wind wind cover, and the inner in cold wind air channel communicates with body of heater, the outer end sealing in cold wind air channel.
The heat accumulating burner capable of the utility model, the shape of wherein said cold wind wind cover and the shape of the fuel nozzle in it adapt.
The heat accumulating burner capable of the utility model, 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 heat accumulating burner capable of the utility model; Combustion-supporting cold wind is without interruption through cool air hose, and the cold wind air channel between cold wind wind cover and fuel nozzle gets in the body of heater, and combustion-supporting cold wind gets in the body of heater fuel mix after-combustion of failing completing combustion with mixed combustion in advance; Improved flame rigidity; Acceleration is heated the firing rate of material, has effectively reduced the concentration of nitrogen oxide in the flue gas, and environment protecting significantly promotes.
Description of drawings
Fig. 1 looks cutaway view for the master of the utility model heat accumulating burner capable;
Fig. 2 is the vertical view cutaway drawing of Fig. 1.
The specific embodiment
As depicted in figs. 1 and 2; The utility model heat accumulating burner capable comprises 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; Have the gap between cold wind wind cover 5 and the fuel nozzle 2 and form cold wind air channel 21, fixing cool air hose 6 on the cold wind wind cover 5, cool air hose 6 overlaps 5 with cold wind wind and communicates; 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.Along 51, the outer end sealing with cold wind air channel 21 was welded with fuel nozzle 2 in interior edge 51 in the outer end of cold wind wind cover 5 was provided with, and cool air hose 6 is welded on the cold wind wind cover 5.The shape of cold wind wind cover 5 and the shape of the fuel nozzle 2 in it adapt.
When using the utility model heat accumulating burner capable; 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.
The utility model heat accumulating burner capable has 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, energy savings about 30 one 70%:
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.
Above-described embodiment describes the preferred implementation of the utility model; Be not that scope to the utility model limits; Under the prerequisite that does not break away from the utility model design spirit; Various distortion and improvement that those of ordinary skills make the technical scheme of the utility model all should fall in the definite protection domain of the utility model claims.
