This report summarizes a two-phase investigation of the technical and economic feasibility of direct pulverized coal firing of marine boilers. Particular emphasis was placed upon application to Great Lakes bulk carriers. The investigation included the study of converting oil-fired boilers to pulverized coal as well as the use of pulverized coal for fueling the unique boiler of a new construction vessel.The Phase 1 feasibility analysis involved a study of overall fueling system requirements and the evaluation of major elements including boilers, pulverizes, burners and pollution control equipment. Preliminary conceptual layouts of systems for conversion and new construction vessels were prepared. Phase 2 established final system design approach and tentative equipment selection for refinement of the Phase 1 conceptual layouts. Boiler performance comparisons relative to fuel consumption with fuel oil, pulverized and stoker coal are presented. Benefits to be gained,relative to fueling system costs for conversion and new construction vessels, are analyzed in the light of today's availability and price of fuel oil and coal.
