Title: Advanced ceramic component development for high temperature indirect gas-fired heating systems. Final report, February 1988-September 1991 and annual report, June 1990-September 1991

Abstract

The CVD silicon carbide process was developed to a point where it can reproducibly deposit material within, around and along the length of tubes, either individually or in multiples. Two methods for sealing the tubes were worked out: one procedure involved a modification of the CVD process, while the other used a sealant coating after the CVD of the silicon carbide. Twenty-three radiant burner tubes 3 inch diameter and 62-1/2 inch long for the Caterpillar field test were made one at a time. The permeabilities of the tubes met the requirements of the furnace at Caterpillar. After eighteen months of operation in the field test of Nextel(TM) 312 Siconex, three tubes failed through the degradation of silicon carbide and one was broken in handling. (A total of 17 tubes were tested.) Installing the Siconex(TM) Corebusters reduced the energy usage by 22 to 25%. A total of six full-sized (8 inch x 94 inch) radiant burner tubes incoorporating the high temperature fiber, Nextel(TM) 440, were coated with silicon carbide. One full-sized 440 tube was painted with a refractory coating and tested at Columbia Gas. Aside from the painted coating flaking off, the tube was able to take the worst that Columbiamore » could give it. Two more full-sized tubes utilizing Nextel(TM) 440 were sealed in the CVD coating process and installed in the pusher forge at SIFCO.« less
