The US Bureau of Mines, the Department of Energy, and 20 US firms have formed a cooperative, cost-sharing group to promote the use of low-Btu coal gas as a fuel for mineral processes and other industrial applications. In a demonstration plant, a Wellman-Galusha gasifier has been used to provide gas for a rotary kiln to demonstrate induration of iron ore pellets for blast furnace use, as well as supplying a combustion test chamber. Details of the plant and its operations are given. Tests using a North Dakota lignite are described very fully. Conclusions are that the most efficient application of this type of gasifier for a Grate-Kiln or straight-gate pelletising system would be an on-site installation; for shaft pelletising application, the gas would need to be pressurised, requiring a more complex installation.
