HC等）の劣化といつた諸現象を呈していた。Conventional configuration and problems thereof Conventionally, this type of combustion apparatus has been configured as shown in FIG. That is, in the combustion chamber 6, a middle cylinder 10 having a large number of air ejection holes 16 on the side wall and an auxiliary combustion cylinder 12 are arranged substantially concentrically, and a liquid fuel atomizing means 3 is introduced into the combustion chamber 6. is present. The fuel is continuously supplied to the combustion chamber from the atomization means 3, and the combustion air is supplied from the air jet hole 16 on the middle cylinder 10 via the wind box 22 connected to the back surface of the combustion chamber bottom 9 by the blower mechanism 20. 6. In this type of combustion device, after initial diffusion combustion, subsequent fuel particles are immediately vaporized at high speed due to combustion heat, diffusion mixing is promoted, and flame-holding combustion occurs in the air jet hole 16 in the upper part of the middle cylinder 10 in a premixed state. A stable flame is formed and various combustion characteristics are maintained only by the total amount of air supplied from each jet hole 16 on the middle cylinder 10. Therefore, during the transitional combustion period from ignition to steady combustion with stable blue flame formation, there is a shortage of combustion air ejected from the middle and lower nozzle holes 16 on the middle cylinder 10 and atomization. Due to insufficient mixing of the fuel with the atomized particles by the means 3, new air is supplied while diffusive combustion is performed, and the flame swirls upward in the combustion chamber 6. As a result, the flame generating soot comes into contact with the surface of the middle cylinder 10, which is the center of the swirling flow in the combustion chamber 6, and deposits soot. Due to repeated operations that pass through such a transitional combustion period, the deposited soot grows and becomes laminated. In addition, among the collision parts of the flying particulates of fuel, at positions far from the flame formation part, the fuel particulates adhere and recombine to form a liquid flow and receive combustion heat to evaporate and vaporize, so tar is deposited on the surface of the collision part. Generate and stick. In this way, soot
The adhesion and growth of tar on the main components inside the vessel, especially near the air nozzle 16 on the middle cylinder 10, causes unevenness in the vaporization/diffusion mixture amount and mixture ratio during steady combustion, and causes combustion noise due to unstable flame holding. and the nature of exhaust gases during ignition and extinguishing (especially CO,
HC, etc.) was exhibiting various phenomena such as deterioration.

多段燃焼による定常燃焼を行なう。 In the above configuration, first, when the motor 17 is energized and the blower mechanism is activated, combustion air flows into the middle cylinder 10 via the wind box 22.
Air is ejected from each air injection hole 16 on the top of the cylinder 0 to the combustion area a and then to the auxiliary combustion cylinder 11.
1, and the air flowing out from the gap in the auxiliary combustion cylinder 11 forms a swirling flow in the premixing region b. Moreover, each air at this time is supplied at a fixed ratio, and a part of the air flows into the premixing area b again via the recirculation area c. After a certain time delay in the operation of the blower mechanism, the ignition electrode 4 is energized and a spark is generated. Thereafter, pressurized liquid fuel is sprayed into the combustion chamber 6 from the spiral injection valve 3 by the operation of the fuel pump 2 . The fuel is diffused and mixed in the swirling flow formed in the combustion chamber 6 by the air ejected from each ejection hole 16, and after reaching a certain mixture ratio and a certain temperature, it is ignited and combusted. The initial flame in this transitional combustion period forms a bright flame with a slight lack of air in the premixing region b, and swirls upward around the auxiliary combustion cylinder 11, supplying new combustion air and performing diffusive combustion. In addition, some of the flame remains at the bottom 9 of the combustion chamber 6 and serves as an ignition source for subsequent fuel. The evaporation and vaporization of the subsequent fuel is further accelerated by receiving the radiant heat of the flame or the heat of the recirculated combustion gas, and the fuel mass is combusted while being supplied with fresh air. Thereafter, the concentration of the premixture further increases and it moves to the upper part of the middle cylinder 10 without being combusted. That is, the bright flame immediately moves to the air nozzle 16 above the middle cylinder 10, takes in air from this nozzle 16, changes to non-bright flame combustion, forms a large number of single-hole flames, and performs multistage combustion. Do this. During this time, the collision part of the flying fuel particles is dispersed to the auxiliary combustion cylinder 11 and the middle cylinder 10, and the re-liquid part is also dispersed, promoting evaporation and vaporization due to heat transfer and radiation, and evaporation and vaporization during flight. is completed and mixing is started. In this way, some of the reliquefied fuel particles at the initial stage are quickly evaporated and vaporized, forming a stable flame at the nozzle hole 16 at the top of the middle cylinder 10.
Performs steady combustion using multi-stage combustion.
