ABSTRACT:

This report focuses on the technical feasibility of coal fines utilization as a boiler fuel in both cyclone and pulverized fuel furnace boilers. The fines examined were representative of the fine fraction of the Camp 1 coal shipment to Republic of South Africa for the commercial scale gasification test. The Camp 1 coal has also been selected as the Tri-State Synfuels design coal and as such the sample had to be characterized both for gasification (coarse fraction) use as well as boiler (fine fraction) use, not only for in-plant steam and power but also for export to nearly potential users. Paul Weir concluded that the Camp 1 raw fines or washed fines are suitable as a potential fuel source in cyclone (wet bottom) and pulverized (dry bottom) furnaces. Several exampes of nearby utilities with the proper combustion equipment were offered. Paul Weir also identified several provisions that should be considered for the design of the storage, handling and transportation systems for the fine coal due to the ability of the coal to retain moisture. These provisions include adequate drainage, covered storage and transport facilities. (ERA citation 08:019497)
