Abstract: A burner including a fuel-containing fluid supply nozzle which supplies a fuel-containing fluid, from a connecting part in a fluid transfer flow passage for transferring a fuel-containing fluid including a fuel and a medium for transfer of the fuel, toward an outlet part provided on a furnace wall surface. The nozzle in its cross section perpendicular to the direction of flow of the fluid has a rectangular, elliptical, or substantially elliptical form having major and minor axis parts from a connecting part in the fluid transfer flow passage toward the outlet part provided on the furnace wall surface. Further, the area of a cross section perpendicular to the direction of flow of the fluid is gradually increased from the connecting part in the fluid transfer flow passage toward the outlet part. Air supply nozzle(s) for supplying combustion air are provided on the outer peripheral part of the nozzle.
