Combustion tests of coal-liquid mixtures at the Pittsburgh Energy Technology Center

Conference ·
OSTI ID:5728677
A research and development program has been under way at the Pittsburgh Energy Technology Center since 1975 to evaluate the potential of coal-liquid mixtures as alternate fuels for oil-designed boilers. The coal-liquid mixtures investigated include coal-oil, coal-water, and coal-methanol-water. The combustion tests have been conducted in 700-hp watertube (24,000 lb/hr steam) and 100-hp (3450 lb/hr steam) firetube boilers originally designed to burn No. 6 fuel oil. This paper reviews the combustion test programs conducted at PETC over the last several years and summarizes selected data resulting from these tests. Information relating to fuel preparation, burner design and performance, and ash deposition is discussed. The applicability of data obtained in the PETC facilities to design of larger-scale industrial and utility boiler installations is assessed. 21 refs., 11 figs., 4 tabs.
