COM utilization can displace as much as 40 to 45% of the oil consumed in an industrial facility, and at the same time permit the user to keep much of his oil-burning steam generation and process equipment intact with a modest degree of retrofitting. Those industries which have the necessary capital, technical experience, and lead-time to burn coal directly should proceed to do so. For those users less versed in the art who wish to gradually introduce coal into their plant fuel economy, COM firing should be explored as an alternative. A preliminary economic evaluation of the costs of retrofitting industrial boilers presently consuming No. 6 residual oil to COM-firing proved favorable. For existing boiler facilities of capacity 100,000 to 500,000 lb steam/hr, and assuming total capital charges of 25%, conversion costs of $2.14 to $2.49/10/sup 6/ Btu were estimated, depending uon whether the slurry fuel was prepared on-site or off-site. Coal was priced at $27 per ton and 1% S residual oil was purchased for $2.17/10/sup 6/ Btu. When the COM was manufactured in a large plant (30 million barrels per year) rather than a small plant (1 million barrels per year), the cost of COM declined from $2.10 to $1.84/10/sup 6/ Btu fired. The idea of introducing a different fuel concept into established markets poses very complex technical and economic problems. However, further studies of this nature should prove valuable in defining potential future markets for COM combustion.
