Preparation and analyses of low-rank coals for combustion applications. Second quarterly report, January 1, 1985-March 31, 1985. [Physical and chemical cleaning]

Technical Report ·
OSTI ID:5756175
This report covers the second quarter of activity on an 18-month project to prepare low-rank coal (LRC) fuel for research applications in DOE advanced combustion technologies programs. Coals from five mines were characterized by physical and chemical cleaning and hot water drying amenability tests. Subbituminous coal from the Eagle Butte Mine was selected from the five for future use as feed stock for production of bulk lots of low ash and low sodium LRC and LRC slurry fuels. The amenability tests indicated that a combination of physical and chemical cleaning would produce a fuel containing 1.36% ash, 8 ppM Na/sub 2/O and 18 ppM K/sub 2/O from the Eagle Butte coal on a dry basis. A micronized slurry loading of 57.5% coal was projected for the hot-water dried coal. 8 refs., 13 figs., 26 tabs.
