Abstract
A composite boiler tube has a fireside surface and a water-side surface and comprises a metallic tubular member having an outer surface and an inner surface. One of the metallic surfaces has an efficiency enhancing coating adhered thereto and providing the composite tube with the fireside surface or the waterside surface. A method of enhancing the efficiency of a boiler tube which comprises a metallic tubular member having an outer surface and an inner surface includes the step of applying a coating of efficiency enhancing material adhered to one of the metallic tube member surfaces, thus to produce a composite boiler tube.
Claims8
A composite boiler tube having a fireside surface and a waterside surface and comprising a metallic tubular member having an outer surface and an inner surface, at least one of said metallic surfaces having an efficiency enhancing coating adhered thereto and providing said composite tube with one of said fireside surface and said waterside surface, wherein the material of said coating is dichlorodimethylsilane or its fluorocarbon composition version and wherein the radial thickness of said coating is on the order of 1.times.10.sup.-6 inch (2.54.times.10.sup.-6 cm).
A method of enhancing the efficiency of a boiler tube comprising a metallic tubular member having an outer surface and an inner surface, said method including the step of applying by vaporization a coating of efficiency enhancing material adhered to one of said surfaces, thus to produce a composite boiler tube, wherein the material of said coating is dichlorodimethylsilane or its fluorocarbon composition version and said coating is applied to a radial thickness on the order of 1.times.10.sup.-6 inch (2.54.times.10.sup.-6 cm).
