IMMERSED HEAT TRANSFER TUBE FOR FLUIDIZED BED BOILER, AND FLUIDIZED BED BOILER

摘要

has sufficient heat transfer effect, and less thickness loss by suppressing the molten salt corrosion-bed heat transfer tube provides a durable fluid bed boiler. -Bed heat transfer tube 5 is fluid inside (water, saturated water, steam, or binary, etc.) are flows inner tube 6 and inner tube 6, the outer periphery to the inner tube pin as a fixed installation in the 37 and the inner tube (6) 0.25 less than the gap in the outer 0.75 7 to have installed, it consists of the inner tube (6) by the protector 8 for protection. The outer peripheral surface of the inner tube (6), a pair of the penetration pin 37 is fixed by the welding penetration pin (37) is fixed by means of welding, like the protector (8). The protector (8), 0.5 mm plurality of slits 81 are formed in the width are each set to 50 interval. ;
