Show The Combustion of a Fuel Mixture Composed of Coal and Light Fuel Oil V. A. Cundy, Ph.D., Louisiana State University D. Maples. Ph.D., Louisiana State University T. Burch7*M.S., Louisiana State University Abstract The development of alternative fuels at the industrial and utility level has expanded dramatically since the 1973 oil embargo. The increasing efforts directed toward the development of the coal-oil technology are clear evidence of this thrust. This paper reports on research directed toward demonstrating the viability of coal-No. 2 fuel oil mixtures as a suitable conventional fuel replacement in existing com-bustors. The paper is devoted to combustion characteristics of these fuel mixtures and does not report on fouling characteristics, corrosion or errosion phenomena, or pollution characteristics. Fuel mixtures at the 50 weight percent coal loading level in No. 2 fuel oil are studied for a number of coal types. Results indicate that the fixed carbon of the parent coal is most important in determining the optimum coal to be used in the mixture for maximum combustion efficiency. Of secondary importance is the coal size which is directly related to fuel viscosity. A complete discussion of the fuels used, the combustion facility, and the results obtained are provided in the paper. i |
