CERAMIC FERRULE AND CERAMIC FERRULE REFRACTORY WALL FOR SHIELDING TUBE SHEET/BOILER TUBE ASSEMBLY OF HEAT EXCHANGER |
摘要 |
A ceramic ferrule, an array of ceramic ferrules, and a ceramic ferrule refractory wall, all for shielding a tube sheet/boiler tube assembly of a heat exchanger connected to an industrial heat source. The head portion of each ferrule replaces conventional cast refractory walls, and has an outer-peripheral shape that allows the ferrules to mate at the operating temperature of the industrial heat source. The mated ferrules expand and contract substantially independently of one another, but form a substantially gas-tight barrier for shielding the tube sheet/boiler tube assembly from the waste gas of the industrial heat source.
