IGNITOR FOR HEAT STORAGE TYPE BURNER

摘要

PURPOSE: An ignitor for heat storage type burner is provided to prevent generation of a scale by an oxidation of a cladding so as to prevent operational defect of the ignitor and incomplete ignition of switching combustion initial main burner by removing the cladding on an electrical resistant body. CONSTITUTION: An ignitor for a heat storage type burner includes an upper outer cladding(14). The upper outer cladding is removed from a mixed gas outlet where an ignition is generated, so that a portion of the upper cladding as a lower cladding being left. In the cladding is installed an insulating body(15) in which an electrically resistant body(16) is provided. The electrically resistant body is installed as to be slanted downward from a leading end of the insulating body. On an inner face of the lower cladding is formed a conductive metal(17).
