傷の危険があり、特殊な材料を必要とし高価であった。[Technical background of the invention and its problems] Conventionally, combustion aids made of ceramic particles hardened with a special binder have generally been used for surface combustion. With this type of combustion aid, a good green flame can be obtained on the surface of the combustion aid due to the mixing effect of the combustion gas and air due to irregularly changing interparticle gaps and the uniformity of the gas flow. A surface combustion burner of the form is obtained. but,
In such a surface combustion burner, the combustion surface of the auxiliary combustion body is heated to a high temperature of 800° C. or more, and there is a risk of cracking and damage due to thermal changes, and special materials are required and expensive.

に突出せしめられている。(3) is a cylindrical casing member that surrounds the group of conductive tubes and is provided so as to sandwich and cover the conductive tubes between insulators. As a result, a cylindrical main mixed gas flow path (7) is formed inside the conduit and the insulator, and a triangular pilot mixed gas flow path (8) is formed between the conduit, the outer surface of the insulator, and the casing member, and this flow The downstream end face (4) of the channel is formed at the combustion surface. (5) is an electrode rod as a spark electrode that is inserted from the upstream end surface of the casing member into the insulator, and its tip forms a pair of electrodes with the conductive tube arranged in a ring around the insulator. (6) is the air and fuel mixed gas inlet provided on the upstream side of the casing member.The cross-sectional area and length of the conductive tube and insulator are designed to keep the vortex of the incoming mixed gas to an appropriate size. Can be erased up to q
It is determined according to the flow rate of the mixed gas at the time of design and the size of the vortex flow at the inlet. Further, the tips of the electrode rod and the conductive tube are made to protrude slightly beyond the upper end of the insulator so as to form a pair of electrodes.

におこなわれる。To explain the operation of the above structure, the mixed gas flowing from the mixed gas inlet flows equally into the main and pilot mixed gas flow paths made up of conductive tubes, insulators, etc. due to the casing members' Ijj. In the mixed gas flow path, the vortex of the mixed gas is eliminated by the movement of the conductive tube, etc., and on the downstream side of the flow path, a uniform flow with fine vortices is formed and flows out from the flow path. On the other hand, at the same time as the mixed gas flows in, a voltage is applied between the tip of the electrode rod and the conductive tube, generating a spark.
The mixed gas flowing out of the channel is ignited, and a good blue flame is formed at the outlet end of the channel. At this time, since the electrode rod and the conductive tube are separated by an insulator, a good pair of electrodes is formed only at the tip, and sparking and ignition occur smoothly.

側に出すと保炎効果はさらに向上する。If the downstream end face of the casing portion is placed slightly downstream of the end face of the conductive tube, the flame holding effect will be further improved.

ことである。In addition, in the above embodiment, a case was explained in which the electrode of the electric vapor stick was configured as a spark electrode as an ignition device, but the invention is not limited to this.
An electrode for flame detection can also be formed between the rod tip and the conductive tube. Furthermore, although the examples show the case where the conductive tubes are arranged in one row, this case is not limited to this, and it goes without saying that the same effect can be obtained even if the conductive tubes are arranged in multiple rows. be.
