By ejecting gaseous fuel and combustion air at equal pressure from the inner peripheral wall surface of a hollow cylindrical gas nozzle chamber with a relatively wide area, the gaseous fuel and combustion air are forced to flow through the blower tube without being forced (stirred and mixed). In addition to efficiently superoxidizing the mixed gas, the mixed gas is heated by the heating action of the vaporizing cylinder while flowing between the inner circumferential wall surface of the vaporizing cylinder and the outer circumferential wall surface of the blower cylinder, and is further heated. The present invention relates to a gaseous fuel combustion device that can carry out agitation and mixing of gaseous fuels to ensure continuous good vaporization combustion.

明する。Conventional technology In the past, while gas fuel, which had been preformed into a vaporized state, was passed from the mixed cylinder to the gas chamber, it was accurately mixed with forced air to form a complete mixed gas, and then the mixture was heated to a constant pressure. A gaseous fuel combustion device capable of stably performing fumarole combustion under certain conditions is well known and was described in, for example, Japanese Utility Model Publication No. 55-40414 prior to the filing of this application, the contents of which are explained with reference to FIG. do.

する。That is, a combustion plate 2 having a large number of gas ejection holes 3 perforated on the surface is disposed over the inner circumference of a bottomed cylindrical combustion cylinder 1 with an open end, and a combustion plate 2 is provided between the combustion cylinder 1 and the combustion plate 2.

通せしめる。In the combustion plate 2 facing the central opening 5 opened at the center of the gas chamber 4, a mixed cylinder 6 with a closed tip and an open base end is disposed between the mixed cylinder 6 and the central opening 5. The mixed cylinder 6 is arranged so that a fume gap 8 is formed between it and the fume chamber T provided around it, and the inside of the mixed cylinder 6 is communicated with the gas chamber 4 through the central opening 5.

態のまま燃焼されるという問題があった。Problems to be solved by the invention By the way, in the conventional gas fuel combustion apparatus of this type,
The gas ejection body for ejecting gaseous fuel into the mixed cylinder has a donut shape as a whole and is placed near the opening on the tip side of the blast cylinder through which combustion air flows, so that it can be used for the intended combustion. Since it is not possible to accurately obtain the amount of air, it is not only impossible to form a large volume of the gas ejecting body, but also the number of gas ejection holes drilled on the surface of the gas ejecting body is necessarily small. The speed of the gaseous fuel that is ejected from each gas nozzle becomes extremely large during vaporization combustion of a large volume, and the gaseous fuel flows into the mixed cylinder with great force (after being ejected, it flows along the inner circumferential surface of the mixed cylinder). Finally, the gaseous fuel is injected into the gas chamber under pressure.Therefore, the gaseous fuel flows into the gas chamber while being separated from the combustion air without being stirred and mixed with the combustion air that is blown into the mixed cylinder. Since it is press-injected, there is a problem that it does not form a perfect mixed gas, and during vaporization combustion, it is combusted in an unstable state.

を安定よ（気化燃焼させることができる。Under such conditions, if a gaseous fuel such as a preformed gas is supplied to the gas nozzle chamber 139, the gaseous fuel will be arranged in a relatively large area inside the base end of the blast tube 127. A large number of gas injection holes 144 are formed in the inner circumferential wall surface 140 of the gas nozzle chamber 139. Gas is ejected evenly inward from each of the gas ejection holes 144, which are perforated in the inner circumferential wall surface 140 of the gas nozzle chamber 139. It collides with air and is stirred and mixed. As a result, while the gaseous fuel is flowing along with the combustion air through the gas nozzle chamber 139 and inside the blower tube 127 to the vaporization tube 121, the two are reliably stirred and mixed to form a mixed gas inside the vaporization tube 121. At the same time, the mixed gas enters the vaporizer cylinder 12.
1 and the outer circumferential surface of the blower tube 127, the mixture is further stirred and mixed to become a complete mixed gas, which is pressurized into the gas chamber 110, and finally the gas chamber 11.
Fumarole combustion is performed under an equal pressure condition from zero. Therefore, how can a small or large volume of gaseous fuel be delivered to the gas nozzle chamber 1?
Even if the combustion air is blown inward from the blower tube 127, simple operations that adjust the amount of combustion air can accurately stir and mix the combustion air inside the blower tube 127, allowing it to After the transition to vaporization combustion, the mixture gas is heated by the vaporization tube 121 to cause the inner circumferential surface of the vaporization tube 121 and the outer circumference of the blower tube 127 to be heated. It is possible to stabilize (vaporize and burn) the gaseous fuel over a long period of time by promoting air-fuel mixture while passing through the gap.

合を促進して完全な混気ガスを起成せしめる。13g is a gas nozzle chamber arranged inside the base end of the blower tube 127, and the gas nozzle chamber 139 has an inner circumferential wall 140 and an outer circumferential wall 141; They are integrally attached to form a sealed hollow cylindrical chamber at both the proximal end side, and are formed at the four ventilation ports 142 on the inner side of the proximal end of the gas nozzle chamber 139 and at the filter ventilation outlet 143 on the inner side of the distal end. There is. A large number of gas ejection holes 14 are provided on the inner peripheral wall 140 of the gas nozzle chamber 139.
At the same time, a plurality of gaseous fuel supply pipes 145 are opened and connected to the base end side of the gas nozzle chamber 139 to supply gas into the gas nozzle chamber 139 from the gaseous fuel supply pipes 145. The gaseous fuel enters the ventilation port 142 from the ventilation chamber 111, and is then vigorously jetted out into the combustion air flowing in the gas nozzle chamber 139 so as to exit from the ventilation outlet 143, thereby stirring the gaseous fuel and the combustion air. Promote mixing to form a complete mixture of gases.

ができる効果を奏する。Effects of the Invention In short, the present invention provides a vaporizer tube 121 with one end open, the open end of this vaporizer tube 121 communicating with the gas chamber 110 disposed around the vaporizer tube 121, and a gas chamber 110 disposed around the vaporizer tube 121 that is inserted into the vaporizer tube 121. Even if the blower tube 127 is equipped with a blower tube 121, a large number of gas ejection holes 14 are provided inside the base end of the blower tube 127.
Since the hollow cylindrical gas nozzle chamber 13B with 4 holes perforated in the inner circumferential wall surface 140 is provided, the volume of the gas nozzle chamber 139 is formed larger than that of conventional gaseous fuel combustion devices, and gas is supplied into the gas nozzle chamber 139. The gaseous fuel is always ejected into the circulating combustion air at an equal pressure state, and the agitation and mixing of the gaseous fuel and combustion air is reliably promoted and a complete mixture of gases is generated. gas to gas chamber 11
It has the effect of producing steam and stably vaporizing and burning it.
