A combustion apparatus including a mixture feeding pipe for injecting a mixture of pulverized coal for combustion air into a furnace, with the mixture being then ignited. A first gas feeding passage is disposed outwardly of the mixture feeding pipe for feeding oxygen-containing gas into the furnace, with a second gas feeding passage being disposed between the gas feeding passage and the mixture feeding pipe, in a radial direction, for feeding the oxygen-containing gas into the furnace. A projection is disposed between the gas feeding passage and the mixture feeding pipe and extends at an exposed end surface thereof into the furnace beyond an exposed end of the mixture feeding pipe, with the projection being hollow for allowing the oxygen-containing gas to flow within the projection.
