The article discusses using different coal technologies for military facilities. Current technology can be used now for direct coal combustion. By 1982, fluidized-bed combustion may be possible. For coal gasification, the Lurgi and Koppers-Totzek processes are promising for the near-term, while the CO/sub 2/-Acceptor process is a long-term option. Coal liquefaction processes are not economically feasible for military use. Boilers can be modified to use coal-derived gas instead of natural gas.
