This paper focuses on the fuel characteristics of Exxon Donor Solvent vacuum bottoms derived from Illinois coal in both recycled and once-through modes. Comprehensive bench-scale and pilot-scale testing to assess fuel properties pertinent to boiler design and operation were carried out. The pulverization, combustion, and ash deposition characteristics of both materials were extensively evaluated on a pilot scale basis. Results of the study indicate that performance characteristics of EDS Illinois bottoms exhibit many similarities to the parent coal and some subtle differences. Combustion characteristics of the recycled bottoms varied from those of the once-through bottoms and from high volatile bituminous coals. The recycle bottoms have distinctive volatile matter evolution, ignition, and burnout properties that are highly temperature sensitive. Ash deposit behavior when firing the bottoms showed high slagging potentials similar to those of Illinois coals. Ash fouling potentials of the bottoms were low.
