<P>PROBLEM TO BE SOLVED: To provide a heat storage type burner having a burner tile to withstand stress from a heat storage body. <P>SOLUTION: An inner tile 1 has a taper surface 1a whose outer edge is decreased in size from the out of core 13 side toward the in-pile 13 side and an fuel nozzle 1b where a heat storage part 4 side and the in-pile 12 side are communicated to each together substantially in the center, and a fuel supply pipe 7 is penetrated through the fuel nozzle 1b and held. A front tile 2 is provided around the outside of the inner tile 1 to be cylindrical and divided into a plurality of parts in the circumferential direction with the inner surface fitted to the taper surface 1a. A metal-made holding member 5 holding the front tile 2 in the inner peripheral surface thereof is cylindrical and buried in a furnace wall 10. The space formed by the inner tile 1, the front tile 2 and a drum tile 3 is taken as a heat storage part 4, and a combustion air nozzle 1c which communicates the heat storage part 4 side to the in-pile 12 side and cannot pass the heat storage body 9 is formed between the inner tile 1 and the outer tile 2. <P>COPYRIGHT: (C)2009,JPO&INPIT |
