Abstract
Disclosed is a burner apparatus comprising an inner tube defining a second channel and an outer tube defining a first channel surrounding the inner tube air supplying means for supplying air to the first channel and the second channel, and gas supplying means for supplying fuel gas to the first channel and the second channel, either the first channel or the second channel being used as a main combustion channel and the other being used as a pilot combustion channel, the main combustion channel and the pilot combustion channel receiving the supply of fuel gas for combusting it. The burner apparatus including a common channel formed at one end of the inner tube and the outer tube for supplying the oxygen-containing gas to the main combustion channel and the pilot combustion channel. A common supply opening discharges the fuel gas of the gas channel in the common channel from the upstream side in the flow direction of the oxygen-containing gas of the pilot combustion channel to the upstream side in the flow direction of the oxygen-containing gas of the main combustion channel. A common shielding member adjusts the inflow amount of the oxygen-containing gas for a common gas supply area which extends in a discharging direction of the fuel gas from the upstream side in the oxygen-containing gas flow direction of the common supply opening and from this common supply opening to the common channel.
