The technical feasibility of gasifying coal-peat and coal-wood chip mixtures with the University of Minnesota, Duluth Campus commercially technology two-stage coal gasifier was demonstrated during a series of experimental tests. Three types of processed peat products were mixed with coal and gasified. The three peat products were: peat briquettes, peat pellets and sod peat. The best peat product for gasification and handling was found to be peat pellets with a diameter of 7/8 inch and a length of .75 to 2 inches. A mixture of 65% coal and 35% peat pellets was found to cause no loss in gasifier efficiency and no operational problems. However, there was found to be no economic advantage in using coal-peat mixtures. The very limited testing performed with coal-wood chip mixtures indicated that the wood chips would be difficult to handle with the coal handling-equipment and there would be no economic advantage in using wood chips. 3 refs., 4 figs., 6 tabs.
