    摘要: The present invention relates to an immersed heat transfer tube installed in a fluidized bed of a fluidized-bed boiler for recovering combustion heat generated when a fuel such as RDF (refuse derived fuel) with high calorific value containing biomass and plastics, or wastes is combusted. An immersed heat transfer tube (5) which is installed in a fluidized bed (3) of a fluidized-bed boiler (1) includes a water tube (6) through which a fluid flows, a cylindrical protector (8) provided at an outer circumferential side of the water tube (6) and configured to protect the water tube (6), and a packed bed (7) provided between the water tube (6) and the protector (8).

    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.
