できる気化バーナを開発した。 First, the applicant has provided a combustion body with a gas chamber inside and a large number of flame nozzles on the surface on both sides or below a gas generating body through which combustion air and mixed gas can flow. The gas generating body and the combustion body are communicated with each other by a communication member, and a fuel supply device is housed inside the base end side of the gas generation body, so that when starting vaporization combustion, the liquefied fuel supplied from the fuel supply device is provided. First, the fuel is live-combusted in the gas generating body, then the gas generating body and the combustion body are internally preheated by the generated raw combustion flame, and when the gas generating body reaches the temperature of the vaporizing atmosphere, the live combustion is stopped and the liquid fuel is Supplying oil to the inside of the gas generator along with combustion air,
We have developed a vaporizing burner that can quickly obtain a mixed gas using a preheating action and then vaporize and burn the mixed gas through a combustion body.

い恐れがあつた。 By the way, in the above-mentioned vaporization burner, when starting vaporization combustion, if raw combustion is performed in the gas generating body and the combustion chamber, incomplete combustion may occur inside if more than a predetermined amount of fuel is accidentally supplied. As a result, the generated medium and the like adhere to the fuel, which significantly reduces the evaporation effect of the fuel supplied thereafter, and there is a possibility that good mixed gas cannot be generated within a short period of time.

Then, the fuel is completely combusted by starting the preheating combustion device 8, and the gas generating body 1, the combustion bodies 2, 2, and the communication member 4 are all preheated from the outside by the raw combustion flame, and the fuel is evaporated and vaporized within a short time. heated to a temperature sufficient to cause When the gas generating body 1, the combustion bodies 2, 2, and the communication member 4 are all preheated to the vaporizing atmosphere temperature in this way, liquid fuel is supplied to the base end side of the gas generating body 1 via the fuel supply device 7. At the same time, combustion air is blown in the direction of the arrow.
Then, the supplied fuel is quickly evaporated and vaporized while being injected into the preheated gas generating body 1 together with the combustion air, and at the same time is stirred and mixed to form a complete mixed gas, which is then passed through the communication member. After the air is injected and stored in the combustion bodies 2 and 2 through the combustion chambers 2 and 2, it is ejected under constant pressure from a number of nozzles 5, and is ignited by the previous raw combustion flame to perform vaporization combustion, and the gas The generator 1 is preheated from the outside. In this way, when the gas generating body 1 is preheated by the generation of vaporization combustion flames and shifted to vaporization combustion, the generation of raw combustion flames by the preheating combustion device 8 is stopped, and the secondary combustion flame is Only air is supplied toward the gas generating body 1, the combustion bodies 2, 2, and the communication member 4, and the replenishing action of the secondary combustion air further promotes the vaporization combustion flame and continues good vaporization combustion.

A combustion body 2 is provided, and the gas generation body 1 and the combustion body 2 are communicated with each other by a communication member 4, and a fuel supply device 7 is housed inside the base end side of the gas generation body 1. However, below the gas generating body 1 at the location where the fuel supply device 7 is installed, there is an air pipe 9 through which secondary air for combustion can flow, and an air pipe 9 near the opening at the tip of the air pipe 9. A spark plug 11 and a fuel spray nozzle 1 are located at and inside the spark plug 11.
A preheating combustion device 8 is provided, and when combustion is started, a combustion flame ejected from the preheating combustion device 8 is used to burn the outside of each of the gas generating body 1, the combustion bodies 2, 2, and the communication member 4. Since the surface is preheated at the same time and only secondary air for combustion can be supplied from the air pipe 9 after transition to vaporization combustion, no matter how many times vaporization combustion is performed, the gas generating body 1, combustion bodies 2, 2 The communication member 4 is simultaneously preheated to the vaporized gas generation temperature within a short time by the combustion flame ejected from the preheating combustion device 8, and when combustion starts, there is no air inside the gas generator 1, the combustion bodies 2, 2, and the communication member 4. This may be because it is possible to shift to vaporization combustion within a short time while completely eliminating the adhesion of medium, etc. that occurs due to complete combustion. By supplying only the secondary air toward the gas generating body 1, the combustion bodies 2, 2, and the communication member 4, the replenishing action of the secondary air for combustion further promotes vaporization combustion. Not only can we provide an efficient and power-saving vaporizing burner that is not found in other burners, but we can also prevent burnout of the gas generating body 1, combustion bodies 2, 2, and communication member 4 and continue vaporizing for a long period of time. This has the effect of maintaining combustion.
