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. A first supply opening supplies the fuel gas into the main combustion channel. The first supply opening is disposed in the main combustion channel with an orientation for discharging the fuel gas toward a more upstream side of the flow direction of the fuel gas than the direction normal to the flow direction of the fuel gas.
