Management of coal waste by energy recovery: mild gasification/flash pyrolysis of coal preparation wastes. Quarterly report, October-December 1985
Feedstock characterization is now complete. Two of the refuse feedstocks, the bituminous coal feedstock and the subbituminous coal feedstock, were obtained and prepared for use in the mild gasification unit (MGU). Construction continued on the mild gasification unit and is estimated to be 95% complete. Most of the major equipment for the MGU is in place and operational. The vacuum pump and hydraulic limit switches are the remaining items to be installed on the unit. The final test plan was prepared. The test plan includes 24 tests, six with subbituminous coal, seven with coal preparation waste, and eleven with bituminous coal. The tests are designed to measure the effects of feedstock, particle size, temperature, residence time, sweep gas, and solid additives on unit performance, product quantity, and product quality. The MGU has performed well during five tests with only minor problems dealing with condensation of the hydrocarbon gases.
