Design Considerations and Operating Experience of the Sanford Com Test Facility

Abstract

A 400 MW oil-fired boiler was fitted with new burner guns and accessories to burn coal/oil mixture (COM) for a 120 full-power burn-day demonstration. Coal unloading and storage, and COM preparation and storage facilities were installed adjacent to the power house. Modifications to the steam generator and firing systems were made as the test program progressed. Burn tests through 50 percent coal (by weight) were completed, and optimization and long term test programs with 40 percent coal were completed.

This paper describes the reasons for the demonstration, the project schedule, and the test facility itself. Discussions are also included of the rationale for equipment and process selection, the test program, and some of the operating experience that should be considered in the design of future permanent facilities.
