Contract objectives are as follows: Develop fuel specifications to serve combustor requirements; Select coals having appropriate compositional and quality characteristics as well as an economically attractive reserve base; Provide quality assurance for both the parent coals and the fuel forms; and deliver premium coal-based fuels to combustor developers as needed for their contract work. Progress is described.

Under the Department of Energy`s Combustor Technology Program, combustor contractors are developing combustor systems for use in residential, commercial, light industrial and industrial retrofit markets. Well-characterized coal based fuels possessing appropriate specifications are required by the contractors for their developmental test programs. Fuels may be dry pulverized or micronized coal or coal-water fuels. In support of these equipment development efforts, Energy International is providing such fuels. A complete list of all of the delivered fuels,the quantities and users are provided in the Appendix. Their fuel needs ranged from small sample quantities (e.g. 5 to 500 lbs.) up to 15 tons per delivery; by now most no longer need fuel. During the twelfth quarter of this contract (August 1, 1989 through October 31, 1989) the primary activities were involved with: (1) Continuation of the procurement, preparation and delivery of coal-based fuels for the combustor contractors. (2) Continuation of the interaction with combustor contractors in order to update their fuel specifications, fuel requirements and delivery schedules. (3) Continuation of the quality control activities to insure that fuel specifications are being met and to determine the cause of any problem which might occur. (4) Issuance of a request-for-bid (Procurement {number_sign}MN-01-2003) for deep cleaning …

Contract objectives are as follows: Develop fuel specifications to serve combustor requirements. Select coals having appropriate compositional and quality characteristics as well as an economically attractive reserve base; Provide quality assurance for both the parent coals and the fuel forms; and deliver premium coal-based fuels to combustor developers as needed for their contract work. Progress is discussed, particulary in slurry fuel preparation and particle size distribution.
