HEAT TRANSFER TUBE FOR FLUIDIZED-BED BOILER |
摘要 |
A heat transfer tube, for a fluidized-bed boiler, having a protector which has sufficient durability in a corrosive wear environment, while reducing an initial cost by avoiding a complex structure, considering maintainability such as installation and replacement, and lowering a risk of crack or deformation is disclosed. The heat transfer tube 1 for use in a fluidized bed of a fluidized-bed boiler includes a water tube 2 through which a fluid flows, a thin protector 4, a thick protector 3 made of casting which are provided at an outer circumferential side of the water tube 2 and are configured to protect the water tube 2, a heat-insulating layer 6 provided between the water tube 2 and the thin protector 4, and a fixing jig 5. The fixing jig 5 is fixed to the thick protector 3 to cause the fixing jig 5 to hold the thin protector 4 provided at the outer circumferential side of the water tube 2. |
