Title: Gas nozzle device
Inventor: KONO KUNITOSHI
IPC: F23Q2/16
Filed: 1985-07-09
Abstract: PURPOSE:To prevent burning continuity of flame formed at the time of initial ignition by placing O-rings for closing gas spouting which are attached in a gas nozzle sliding in a gas tank and which also close gas spouting at one time in the middle of nozzle siding motion. CONSTITUTION:Gas in a gas tank 1 flows through a gas inflow hole 1a in the gas tank 1 and a gas inflow hole 2a in a gas nozzle 2 and is spouted and preheats catalyst at the same time of ignition. When the gas inflow hole 1a is closed by an O-ring 3a, gas is not spouted and flame formed at the ignition time is blown out. Gas which flows from the gas inflow hole 1a in the gas tank 1 to a inflow hole 2b at the bottom of the gas nozzle 2 and then is spouted from the gas nozzle 2 and catalyst reaction starts smoothly by the preheated catalyst. Thus, as gas is spouted continuously immediately after flame formed at the ignition time is blown out to start only the catalyst reaction smoothly, burning of the device etc. is prevented as flame is surely blown out.
