Title: Gas burner
Inventor: SUZUKI TAKESHI
IPC: F23D14/02
Filed: 1999-05-17
Abstract: PROBLEM TO BE SOLVED: To stably combust a gas burner. SOLUTION: There are disposed in an adjacent manner a concentrated mixed gas nozzle where concentrated mixed gas is formed and is injected into a furnace, and a thin mixed gas nozzle 105 where thin mixed gas is formed and is injected into a furnace. Thick mixed gas is fired to form a thick mixed gas flame, whereby the thin mixed gas injected from the thin mixed gas nozzle is combusted by the injection to the thick mixed gas flame and with radiation heat in the furnace. Sealing gas 119b is injected around the thin mixed gas injected from the thin mixed gas nozzle to shield the thin mixed gas just after the injection, and high fuel concentration flame insulation gas fuel 121 is supplied to the neighborhood of an outlet of the thick mixed gas nozzle to keep the flame.  As a result, a back fire is prevented owing to firing of the tin mixed gas just after the injection of the thin mixed gas nozzle, and flame as a firing source is kept with the aid of combustion of the flame insulating gas fuel to stabilize the combustion of the thick mixed gas flame and hence ensure the entire stabilized combustion of the gas burner 200.
