Abstract

The utility model belongs to the dual-purpose combustor for oil gas. The utility model relates to an umbrella-shaped radiation combustor, which is composed of an air inlet pipe, an oil inlet pipe, a vaporizing oil nozzle, a stable burning hood, a fire-proof ring, a furnace chamber and a heat radiation board; the oil inlet pipe and the air inlet pipe are arranged on the lower part of a furnace, and the stable burning cover is covered on the vaporizing oil nozzle; the furnace is square-shaped, and the fire-proof ring is arranged on the bottom part of the furnace and the upper part of the stable burning cover; the heat radiation board is umbrella-shaped, and is arranged on the fire-proof ring. The combustor of the umbrella-shaped radiation combustor changes the cylindrical-shaped furnace into the square-shaped furnace, for enlarging the oxygen sending space; the flame is ejected from the furnace hole, and is collectively reflected on the bottom part of a cooker through the umbrella-shaped heat radiation board, and for improving the combustion temperature for 10 DEG Celsius. Compared with the umbrella-shaped radiation combustor and the existing combustor, and more than 20 percent of the combustible can be saved.

Description

Umbrella shape thermal radiation burner

The utility model belongs to the oil-gas two-way burner.

Liquid fuel combustion belongs to heterogeneous property diffusion combustion, because some liquid such as diesel oil burning-point are higher, can not light with fire under the normal temperature, therefore before burning, must carry out oil droplet cracking, atomizing, form one deck fuel-steam on the fuel oil surface, and burn simultaneously with after air mixes, in industrial furnace and food cooking stove, oil atomization and mix by burner with air and to realize will be so the supply mode of the structure of burner, shape, size, air dielectric will play decisive role to the liquid fuel combustion overall process.Major part is the low pressure atomising burner in the food cooking stove of public use at present, this burner generally is made up of burner cylindrical shell, blast pipe, joint oil pipe, vapo(u)rizing oil nozzle and interior rotary fluid, the joint oil pipe enters from the cylindrical shell side, blast pipe enters from the cylindrical shell bottom, be vertical between the two, the circular hole opening is arranged on the interior rotary fluid.Shortcomings such as this burner ubiquity that oil droplet atomizing is inhomogeneous, oil and air mixing velocity are slow, incomplete make combustion efficiency undesirable.

The purpose of this utility model is intended to overcome the deficiencies in the prior art, and a kind of flameholding, umbrella shape thermal radiation burner completely are provided.

Umbrella shape thermal radiation burner described in the utility model is made up of blast pipe, oil inlet pipe, vapo(u)rizing oil nozzle, steady combustion cover, fire-resistant circle, burner hearth and thermal radiation plate, oil inlet pipe and blast pipe are positioned at lower furnace portion, steady combustion covers on the vapo(u)rizing oil nozzle, burner hearth is square, fire-resistant circle places on burner hearth bottom, the steady combustion cover, the thermal radiation plate is a umbrella shape, places on the fire-resistant circle.

It is square burner hearth that burner described in the utility model changes the cylindrical shape burner hearth, increases to send the oxygen space, and flame is concentrated through umbrella shape thermal radiation plate through the fire door ejection and reflexed to the bottom of a pan, has improved ignition temperature (about 100 ℃).Device described in the utility model is saved fuel oil more than 20% than existing burner.

Below in conjunction with accompanying drawing the utility model is further described.

Fig. 1 is the utility model front view.

Fig. 2 is the utility model vertical view.

Accompanying drawing is an embodiment of the present utility model, in the present embodiment, oil inlet pipe 1, blast pipe 8 are positioned at the bottom of burner hearth 5, steady combustion cover 4 covers on the vapo(u)rizing oil nozzle 3, burner hearth 5 is square, and fire-resistant circle 6 places burner hearth 5 bottoms, and on steady combustion cover 4, thermal radiation plate 7 is a umbrella shape, places on the fire-resistant circle 6.Thermal radiation plate 7 upper surfaces scribble heat-resisting paint.Whole device is supported by support 2 and places.

Claims
