OSTI ID:6780790

This report presents the Phase II results of a combustion program designed to assess the feasibility of utilizing coal/oil/water (COW) emulsions as a fuel for fire tube package boilers. Also examined was the effect of the addition of alkaline absorbents to the fuel for sulfur dioxide capture. Presented are the findings of testing involving optimizing sulfur dioxide removal while still maintaining a rheologically favorable fuel. Overall performance of COW as a boiler fuel was evaluated over long term operation. Emphasis was placed on burner design as well as coal characteristics. Three different bituminous coals were used during this program. Results indicate that COW emulsions may be a feasible alternative for oil in industrial fire tube boilers if the major problem, deposition buildup, can be resolved. This appears possible with a proper soot blower design. Soda ash is a viable means for obtaining at least 80% removal, using a 1:1 molar ratio. However, the deposition problem with soda ash indicated that stack injection may be a more feasible approach.
