The solvent refining of coal is one of several approaches currently being evaluated by Government and private sources to produce a relatively clean fuel from coal. Solvent-refined coal (SRC) processes are presently being evaluated on the pilot-plant scale at Wilsonville, Alabama and Tacoma, Washington. This fuel is a low melting point, low ash, low-sulfur solid fuel which is intended to be a substitute for coal. The Babcock and Wilcox Company first evaluated a deashed coal in 1965 for the Office of Coal Research. That product had many of the properties of SRC. In 1974 the company entered into contract with the Electric Power Research Institute (EPRI) to study solvent-refined coal. Initial studies included: laboratory fuel analyses, pulverizing tests in an impact mill, conveying and storage of pulverized and unpulverized solvent-refined coal, and combustion of pulverized solvent-refined coal in a 500-lb/h test furnace. A dual-register burner was selected as having the best chance of any conventional B and W burners for improving combustion efficiency. With EPRI's support, work began in the spring of 1976 to evaluate the adequacy of this burner to combust pulverized solvent-refined coal. The test program involved a comparative evaluation between SRC and a high volatile bituminous coal. Results of the tests are tabulated and analyzed. (JRD)
