Abstract

PURPOSE:To prevent burning from coming into lift condition and keep blue flame burning by installing a suppress and control plate for mixed gas flow velocity which forms diffusing parts for gas spouting having convex shape outward corresponding to vent pipes and suppressing parts for gas spouting having concave shape corresponding to the parts between each vent pipe. CONSTITUTION:Burning air is sent into a vaporizing cylinder 6 by its high speed rotation and gas is spouted into burning cylinder 1 from a gas chamber 3 through a number of gas spouting holes 5. Air is sent to a ring-shaped spouting path 15 through a number of vent pipes 16 from an air blasting chamber 2 and spouted into the cylinder 1. Fuel is diffused and made minute in the cylinder 6 and spouted into the cylinder 1 and burnt. The installation of many pierced pipes 16 and a suppress and control plate 18 for mixed gas velocity which controls mixed gas flow velocity uniformly in the chamber 3 with many pipes 16 penetrated therethrough causes mixed gas flow velocity kept in uniform condition as a whole. Spouting burning from the holes 5 on a burning plate 4 is prevented from partially coming into lift condition to be kept in constantly stable blue flame burning.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a vaporizing burner that burns a mixed gas generated in a vaporizing cylinder through a large number of gas ejection holes in a full gas chamber.

Conventional technology Conventionally, a gas chamber with a large number of gas ejection holes is arranged in a bottomed cylindrical combustion cylinder adjacent to a blowing chamber, and an annular blowhole passage is provided between the base end open side and the gas chamber. A vaporizing burner in which a vaporizing cylinder is rotatably disposed so as to form a gas chamber, and the annular fume passage is communicated with a blowing chamber through a number of vent pipes penetrating the gas chamber has been disclosed before the filing of this application, for example in Japanese Patent Publication No. Showa 57-7
As described in Japanese Patent No. 3306 (previously developed by the present applicant and known).

Problems to be Solved by the Invention Incidentally, in the above-mentioned known vaporizing burner, a large number of ventilation pipes are provided on the vaporizing cylinder side of the gas chamber, which completely penetrate through the gas chamber, and this becomes an obstacle to the circulation of the mixed gas. There is a large difference in the flow velocity of the air-fuel mixture between one part of the ventilation pipe and the other part, and as a result, there is a phenomenon in which the fumarole combustion from the gas nozzle of the combustion plate falls into a state of partial lift.

Therefore, the present invention solves all of the above problems by equalizing the flow rate of mixed gas throughout the gas chamber even if a large number of vent pipes are installed through the gas chamber. .

SUMMARY OF THE INVENTION The technical object of the invention is therefore to simply and reliably equalize the total flow rate of the gas mixture in the gas chamber. In order to solve all of these technical problems, in particular, we installed a gas chamber with a large number of gas injection holes in a bottomed cylindrical combustion cylinder adjacent to the blast chamber. The carburetor is disposed so as to be fully rotatable so that its open base side communicates with the gas chamber and an annular fume passage is formed between the open base side and the gas chamber. , gas chamber?
The gas chamber is connected to the ventilation chamber by a large number of ventilation pipes passing through it, and there is a gas ejection opening that is convex outward corresponding to the ventilation pipes, and a space between each ventilation pipe. This vaporizing burner is characterized in that it is provided with an air mixture gas flow rate suppression adjustment plate formed with a concave metal gas ejection suppressing portion corresponding to the above.

Made for The above technical means works as follows (see drawing).

If the burner is started now, the vaporizing cylinder 6 will rotate at high speed, and the air blowing chamber 2 will blow air from the air blower 8? After that, combustion air is blown into the vaporization cylinder 6, and then from the gas chamber 3 to a large number of gas injection holes 5.
G is injected into the combustion cylinder 1 through the gas. At the same time, combustion air is blown from the ventilation chamber 2 to the annular jet passage 15 through a large number of ventilation pipes 16, and is injected into the combustion cylinder 1.

If fuel is supplied under such conditions, the fuel will be diffused and atomized in the vaporization cylinder 6, and further atomized by the combustion air injection action from the air blower 8. Furthermore, it is sprayed from the open end of the vaporizer cylinder 6 into the combustion cylinder 1, and is ignited to be live-combusted. Then, the entire vaporization cylinder 6 is heated by the generated raw combustion flame, so the fuel supplied from then on on the 6th day of the vaporization cylinder is evaporated and vaporized, mixed with the combustion air to form a mixture of gases, and this mixture of gases Gas is injected into the gas chamber 3 and stored therein, and a large number of gas ejection holes 5...
・It is ejected into the combustion tube 1 and vaporized and burned.

By the way, in the gas chamber 3, there are a large number of ventilation pipes 16 passing through the gas chamber 3. Since the flow rate suppression adjustment plate 18 is provided, even if a large number of ventilation pipes 16 pass through the gas chamber 3, the flow rate of the mixed gas in the gas chamber 3 can be controlled. is maintained evenly over the whole, and the fume combustion from the gas jet holes 5 of the combustion plate 4 does not become partially lifted, and stable blue combustion is maintained at all times. be able to.
