Abstract

An oil fired burner (30A) for warming which is provided adjacent to the outer periphery of a pulverized coal burner for charging pulverized coal and air into a furnace is provided with an oil gun (32) disposed at the center of an outlet opening of a nozzle body (31) having an approximately rectangular cross section in order to charge oil fuel and a secondary air charging port (40) provided so as to surround the outer periphery of the oil gun (32) and the secondary air charging port (40) is configured from a central arc part (41) having a shape approximately similar to a circular diffuser (34) attached to the leading end side of the oil gun (32) and rectangular parts (42L 42R) provided continuously with both sides of the central arc part (41) and each having a narrowed space between surfaces in the direction of the adjacency such that the distance from the pulverized coal burner is increased.
