Abstract

PURPOSE:To obtain the blue flame combustion of kerosine with a simple constitution having no evaporating surface by a method wherein the titled burner is constituted of a conical flame keeping plate, provided with a multiple of small holes, and a combustion tube while an annular plate is connected to the top of the combustion tube and the flame keeping plate is arranged so as to be contacted with or close to the annular plate. CONSTITUTION:Combustion gas flows from the downstream end of a combustion tube 1 into a furnace, however, a part of the combustion gas flows in the direction of a spray nozzle 3 and circulates in the flame keeping plate 2. The circulation of the combustion gas is more activated by making the spray pattern of the spray nozzle 3 a hollow type and whereby the temperatures of the spray nozzle 3 and a space around the nozzle 3 are increased. The temperature rise of the space around the spray nozzle 3 is started simultaneously with the ignition and the most of fuel is evaporated in high-temperature atmosphere simultaneously with the spraying of the fuel, thereafter, the fuel is burnt in a condition that it contains very small amount of oil drops and generates blue flames.

(Prior art) Conventionally, a burner type burner, which has been widely used as a simple oil combustion device, consists of a spray nozzle and a disc or conical diffuser (flame holding plate).The spray is sprayed from a nozzle located in the center of the diffuser. The oil droplets are stirred by vortices and turbulence, mix with combustion air in the combustion chamber, and burn.

In this case, the diffuser provides a flame stabilizing effect by forming a low flow velocity region at the rear thereof and generating a swirling flow due to the swirling slit. The flame generated by this burner is yellow and relatively long, and has a limited capacity for carrying out load combustion in the blast furnace.

In addition, in a kerosene vaporization combustion device, fuel is dropped onto a vaporization surface that has been heated in advance by an electric heater or other heat source to vaporize it, or the vaporization surface is heated by self-combustion heat. Burners that spray and vaporize fuel are common. These burners burn the fuel after it has been vaporized, so they produce less soot and can easily produce two short flames. It is difficult to control the temperature for vaporization, and if the temperature gets too high, the kerosene decomposes, causing tar to adhere and worsening the combustion condition, and the structure is complicated. There are some drawbacks.

The other end is connected to a blower, and the combustion air sent by the blower passes through the air hole 5 of the flame holding plate 2 and flows into the furnace. The flame stabilizing plate 2 has a conical shape, and a spray nozzle 3 is located at the small diameter end, and the spray nozzle 3 is surrounded by a pipe-shaped partition wall connected to the small diameter end of the flame stabilizing plate 2. On the other hand, the first spray nozzle 3 is connected to an oil pump through an oil feed pipe 4, and the fuel pressurized by the oil pump is sprayed by the spray nozzle 3 and ignited by the spark generated by the ignition device. is equal to or larger than the spreading angle, and the sprayed oil droplets scatter along the flame stabilizing plate/inner surface.The combustion air jetted from the air holes 5 intersects the flow of the sprayed oil droplets at right angles to stabilize the flame. Rapid mixing and combustion occur inside the plate, and a comparatively soft short flame is formed from the flame holding plate 2 toward the inside of the furnace.
The flame is held by a large number of vortices generated around the air holes 5 on the inner surface of the tube.

Combustion gas flows into the furnace from the downstream end of the combustion tube 1, but a portion of the combustion gas flows toward the spray nozzle 3 and circulates inside the flame-holding plate. By making the spray pattern of the spray nozzle 3 hollow, the circulation of this combustion gas becomes more active and the temperature of the spray nozzle 3 and the space around it increases. The temperature rise in the space around the spray nozzle 3 starts at the same time as ignition, and the fuel is mostly vaporized in the high-temperature atmosphere at the same time as the spray, and then burns with very few oil droplets, producing a blue flame. This vaporization of the sprayed oil droplets occurs not only when a certain period of time has passed after ignition and the fuel in the spray nozzle 3 has risen above the outside air temperature, but also when the fuel temperature is the same as the outside air temperature. It will be done. Also.

Second, the atomized oil droplets are rapidly vaporized by mixing with high-temperature combustion gas.The second type is similar to a conventional vaporizing burner that uses combustion heat to heat the vaporizing surface made of heat-resistant steel, ceramic, sox, etc. There is no need for yellow flame combustion time until the temperature of the vaporization surface rises.

As in the embodiment shown in FIG. 6, a small hole for introducing a small amount of air may be provided in the partition wall around the spray nozzle 3. This small hole is effective for keeping the spray nozzle 3 clean, but
The amount of air introduced from this small hole is smaller than the amount of air passing through the air holes 5 of the flame holding plate 2, and the circulation of the dead flame and combustion gas inside the flame holding plate 2 is prevented. This should never happen.

Further, in the present invention, the burner tip portion may have a shape like the embodiments shown in FIGS. 2, 3, and 4.

(Effects of the Invention) According to the device of the present invention, low 02 operation is possible by adjusting the distribution of air flowing in from the air holes 5 of the flame stabilizing plate 2, the position of the spray nozzle 3, the fuel spray angle, etc., and smoke is generated. Combustion without combustion is possible. In addition, because the flame is short due to high-speed combustion, it is possible to burn at several times the furnace load compared to conventional gun-type burners. In addition, ignition and extinguishing are instantaneous, there is no preheating time required for conventional vaporizing burners that use a heater or self-combustion heat, and there is no irregular combustion that tends to generate soot or CO. no time.

Good combustion conditions according to the present invention can be obtained simply by changing the fuel. Furthermore, since a preheater is not required and the device is simple, it has the effect that a device with a larger combustion amount than a conventional vaporizing burner can be manufactured at a lower cost.
