BURNER, REACTION FURNACE, AND POWER PLANT

Japanese Patent JP2018169061

A

To relax a bending stress by effectively absorbing displacement caused by thermal expansion and to enhance durability by decreasing the weight load resulting from an intermediate pipe member.SOLUTION: A burner 1 comprises a guide cylinder 4 with one end fixed to a furnace body and the other end penetrating a pressure vessel to extend toward the outside of the pressure vessel, and an oxidizer pipe 3 disposed inside the guide cylinder 4. The guide cylinder 4 includes a first cylinder member 41 supported by the furnace body, a second cylinder member 42 supported by the pressure vessel 11, an intermediate cylinder member 43 disposed between the first cylinder member 41 and the second cylinder member 42, outside displacement absorbing members 44 and 45 disposed between the first cylinder member 41 and the intermediate cylinder member 43 and between the intermediate cylinder member 43 and the second cylinder member 42 respectively, and a first connection member 5 and a second connection member 6 connecting the first cylinder member 41 and the intermediate cylinder member 43, and the intermediate cylinder member 43 and the second cylinder member 42 respectively across the outside displacement absorbing members 44 and 45.SELECTED DRAWING: Figure 3
