Filed: 1990-03-28
Abstract: PURPOSE:To prevent the generation of thermal deformation and of a crack, so as to improve yield by covering the end part of a bulb with a heat-resistant cover, and by sealing the bulb and a stem at the same time. CONSTITUTION:When a gas flame is blown out of gas nozzles 5... for stem sealing of a burner 2 for stem sealing, and an opening end of a bulb A as well as a flare part C of a stem B abutted on the opening end of the bulb A are to be heated thereby, the end part of the bulb A is covered with a heat- resistant cover 25.
