The burner apparatus comprises a water cooled wall located in an opening of a burner tile, a cooling water supply device for supplying cooling water to the backside surface of the water cooled wall, and an opening formed in the water cooled wall. The forward end portion of a fuel injection nozzle provided on the forward end of the burner is fitted in the opening formed in the water cooled wall.
