The present project covers the second phase of a three phase project to develop, at a commercial scale, an air cooled, cyclone coal combustor for application to the conversion of oil/gas designed boilers to coal. This combustor is designed to retain sufficient ash inside the combustor to allow its use in oil/gas designed boilers; and to simultaneously reduce the NO/sub x/ and SO/sub 2/ emissions to levels that meet or exceed the EPA New Source Performance Standards. During this second project phase, a 30 MMBtu/hr capacity combustor was installed on a 23 MMBtu/hr, oil designed package boiler at the Keeler plant in Williamsport, PA. Two parametric tests with a total duration of 40 hours were performed. A total of 10 tons of coal water slurry was consumed. The combustor operated as designed, especially the critical air cooling and slag tap sections of the combustor. It was determined that the combustor is capable of efficiently burning the slurry fuel at stoichiometric conditions in the combustor. 10 refs., 9 figs., 1 tab.
