PURPOSE:To simplify the detecting of combustion and improve the workability and serviceabilty by a method wherein a sub-combustion cylinder is installed vertically on the bottom of a burning chamber as electrically insulated from a can body, and the sub-combustion cylinder is used as a burning detecting body. CONSTITUTION:A sub-combustion cylinder 7 is installed as electrically insulated from the bottom plate 14 of a can body 1, an opening 7' is provided at the location opposing to a nozzle 4, the sub-combustion cylinder 7 itself becomes a burning detecting body. For instance, a brick 15 is provided on a bottom plate 14, the sub-combustion cylinder 7 is installed on said brick 15. Thereby, the workability and serviceability are improved, also the parts related to a frame rod is not required, the reducing of cost can be achieved. |
