つたものである。[Detailed description of the invention] This invention relates to a horizontal blowing Bunsen burner, in particular, the axis of the gas jet nozzle 1 and the axis of the burner bench lily tube are parallel by about 0.5 to 1.0 mm, and the axis of the nozzle 1 is always parallel to the axis of the burner. By displacing the center so that it is below the axis of the bench lily tube, the effect of back pressure on the gas jet is reduced and the flow is made smooth, and the suction of primary air is improved to prevent red flames, soot generation, incomplete combustion, etc. The aim is to eliminate the cause and ensure complete combustion at all times to improve safety.

た。 In the conventional burner of this type, as shown in Fig. 1, the axis a' of the nozzle 1' and the axis a' of the bench lily tube 2' are aligned.
b' are arranged on the same axis, the nozzle jet is ejected toward the axis of the bench lily tube 2'. However, due to a nozzle installation error, the axis a' of the nozzle 1' is slightly shifted upward from the axis b' of the bench lily tube 2', and the velocity of the nozzle jet is suppressed due to the influence of the front wall. At the same time, the pressure (back pressure) C' inside the burner unit is directly opposed to the nozzle jet, which slows down the flow velocity of the gas jet nozzle jet and worsens the suction of primary air.
The red flame grows. For this reason, gases with a high calorific value (for example, 13A, LPG) often have the disadvantage of causing red flames, soot generation, and incomplete combustion.

ある。 FIG. 2 shows an embodiment of this invention. In the drawing, 1 is a gas ejection nozzle of a side-blowing Bunsen burner, and the axis a of the nozzle 1 is about 0.5 to Install it by displacing it approximately 1.0mm downward in parallel. That is, the axis a of the nozzle 1
When shifted with respect to the axis b of the bench lily tube 2, the range of extremely small red flames (red flames of 5 mm or less) is approximately below the zero point on the same axis as the axis b of the bench lily tube 2.
The range is up to 1.5 mm, and even in the range of extremely small red flames, this invention takes into account installation errors and allows for vertical clearance approximately 0.5 to 1.0 mm from the axis b of the bench lily tube 2.
The range below mm is the installation range of the nozzle 1. Therefore, if the nozzle 1 is installed in the above range, the influence of the wall that obstructs the flow in front of the gas jet will be reduced, and the nozzle jet will rise smoothly from the lower side of the bench lily tube 2 along the curved wall of the rising part. Therefore, since the back pressure C inside the burner unit is reduced from directly opposing the nozzle jet, the flow of the gas jet from the nozzle 1 is unaffected by the back pressure and becomes smooth, resulting in very good primary air suction. Become. Also,
The nozzle sensor may be misaligned due to slight assembly errors when multiple burners A are assembled in a row, or the center of the nozzle and the bench lily may be misaligned above or above the axis of the bench lily due to errors during nozzle manufacturing or installation errors. When it gets hot, the suction of primary air becomes poor due to the above-mentioned reasons, resulting in red fire.
In this design, the center of the nozzle is set at 0.5~0.5~ below the axis of the bench lily tube within the extremely small red flame range.
Since the range is 1.0 mm, it is easy to install the nozzle center when assembling the nozzle, and even if there is a slight deviation from the above range due to installation error, there is a margin of a small red flame range on both sides. Sufficient primary air is sucked in to achieve complete combustion.
Therefore, the gas flow from the gas jet nozzle becomes smooth and primary air can be easily sucked.
Even with gases with high calorific values such as LPG and 13A gas, it is possible to eliminate red flames, soot generation, incomplete combustion, etc., and this type of gas combustor can be used safely.
