本考案は、灯油等の液体燃料燃焼装置に関する
ものであり、燃焼性に優れ又燃焼騒音を著しく低
減せしめた燃焼装置の提供を目的としたものであ
る。[Detailed Description of the Invention] The present invention relates to a combustion device for liquid fuel such as kerosene, and aims to provide a combustion device that has excellent combustibility and significantly reduces combustion noise.
従来より液体燃料燃焼方式としては、ガン式、
ポツト式、ガス化式等がある。 Traditionally, liquid fuel combustion methods include gun type,
There are pot type, gasification type, etc.
ガン式では加圧燃料をノズルより拡散噴霧し、
燃焼用空気と混合しながら拡散燃焼する為にスス
や一酸化炭素が発生し易く燃焼騒音が大きい。 The gun type diffuses and sprays pressurized fuel from the nozzle,
Because it undergoes diffuse combustion while mixing with combustion air, soot and carbon monoxide are likely to be generated and combustion noise is large.
又、ポツト式ではポツト底部の蒸発皿に注入さ
れた液体燃料に点火し、その燃焼熱でポツト部を
加熱し、更にその熱により燃料の気化が促進さ
れ、側壁から導入される空気と接触、混合しなが
ら燃焼する拡散燃焼である為燃焼室の形状が大き
くなり、燃焼の立上がりが遅くすすの発生も多
い。 In addition, in the pot type, the liquid fuel injected into the evaporation dish at the bottom of the pot is ignited, the combustion heat heats the pot, and the heat promotes the vaporization of the fuel, which comes into contact with the air introduced from the side wall. Since it is a diffusion combustion in which combustion is performed while mixing, the shape of the combustion chamber is large, the startup of combustion is slow, and a lot of soot is generated.

に激しい臭気を発生するなどの欠点があつた。 In the gasification method, it is dropped onto a vaporization surface that has been heated in advance with an electric heater or other heat source, or it is dispersed and supplied by a jet stream of combustion air.
Fuel is supplied to a rotating disk, etc., and the fuel is scattered by centrifugal force, and the fuel is brought into contact with a pre-heated vaporizing surface, vaporized, mixed with air, and then combusted, but it is necessary to heat the vaporizing surface in advance. It takes a considerable amount of time to combust, and a considerable amount of tar contained in the fuel becomes a residue that adheres to the vaporization surface, inhibiting fuel vaporization, and producing a strong odor when extinguishing a fire. There were drawbacks such as:

のバーナの提供を目的とするものである。 Therefore, the present invention aims to take advantage of the advantages of each method by burning some of the pressure-sprayed fuel particles inside the carburetor to increase the vaporization efficiency of the main fuel inside the carburetor. By generating a quasi-premixed flame inside the carburetor, and by generating a premixed flame outside the carburetor to heat the carburetor from the outside, the combustion effect is increased and the burner has low noise. It is intended for the purpose of providing.

焼熱によつて定常燃焼中のガス化を維持する。 When energized, a fan motor (not shown) operates,
After a few seconds, the electromagnetic pump, control nozzle 1 and spark plug 10
is activated. The fuel pressurized by the electromagnetic pump is controlled to a predetermined flow rate by the control nozzle 1,
It is ejected into the vaporizer cylinder 9. On the other hand, combustion air flows into the burner case 2 from the blower fan, passes through the primary air inlet 4, enters the primary air cylinder 3, and enters the carburetor cylinder from the primary air blowing opening 14 as primary air for combustion. 9 and ejects it while mixing with fuel. The ejected fuel is ignited by the spark energy of the ignition plug 10 and starts combustion in the vaporizer cylinder 9. This flame is a flame formed by spark energy.
The amount of primary air that enters the vaporization cylinder is 10 to 30% of the theoretical air.
Although it is only a small amount and part of the fuel is burned,
After a few seconds, the temperature of the vaporization cylinder 9 rises, and the ambient temperature also rises, so that the remaining fuel is gasified. When the operation of the spark plug 10 is stopped several seconds after ignition, the flame formed by this energy disappears, but the air ejected from the combustion air port 6 of the combustion cone 5 has a high flow rate, so that combustion in the vaporization cylinder 9 is prevented. The combustion air enters from the combustion air port 12, becomes a properly premixed gas only in that part of the vaporization tube 9, and forms a blue flame in the vaporization tube 9 using the combustion air port 12 as a holding surface. This combustion heat maintains gasification during steady combustion.

3, the gas flows into the gas chamber 22 via the partition tube 24, the gas is mixed with air in the gas chamber 22, and the gas flows into the combustion port 25.
The fuel is ejected from the fuel and ignited by the igniter 10, resulting in premixed blue flame combustion. The initial diffusion flame in the vaporization cylinder 9 will not enter the gas chamber 22 by setting the area of each gas outlet 13 to be minute.

る。 As described above, the present invention burns a portion of the sprayed liquid fuel using the inner surface of the vaporizer tube 9 as a holding surface, creating a stable flame and stabilizing the condition inside the vaporizer tube 9, thereby achieving good results. Moreover, uniform vaporization characteristics can be maintained. Further, since the gasified fuel is sent to the gas chamber, mixed with air in the gas chamber, and subjected to combustion, the noise level is significantly improved compared to the conventional vaporization diffusion combustion type gasification burner. Moreover, since the vaporization cylinder is heated from both the inside and outside, the vaporization efficiency is good and the combustibility is also good.
