INVESTIGATION OF MATERIALS FOR HIGH TEMPERATURE FOSSIL FUEL HEATED BURNERS.

Abstract

The effort included a materials evaluation, burner geometry design, and burner evaluation. The materials evaluation eliminated metals from consideration, and of the non metals only silicon carbide and alumina were promising. Silicon carbide was selected because of its light weight and superior resistance to thermal stress. The burner geometry investigation included tests on six designs. The resultant geometry incorporated a six-combustion-chamber unit incorporating preheating of the incoming air and partial premixing of the cold air and propane fuel. The proof test models were operated satisfactorily to temperatures in excess of 1000 C. However, particles of silicon carbide clogged the jets at this temperature and limited higher temperature operation. It was indicated that this condition can be corrected and satisfactory operation obtained at temperatures up to 1750 C. (Author)
