Development of a coal/water-slurry-fueled diesel engine for industrial cogeneration: Final and summary report
Purpose of the program was to foster the long-range development of a coal/water slurry fuel fired slow-speed, two-stroke diesel engine for efficient and economical power generation in the 8 to 30 MW range for use in industrial cogeneration applications. Five Topical Reports have been prepared. This report contains a short description of the process used to select four coal/water slurries for testing in a single cylinder, slow-speed engine and the test facility and a summary of the program results. The program results conclusively showed that the thermal efficiency of a coal/water engine is comparable to that of a diesel fueled engine and produces considerably lower amounts of exhaust emissions. Furthermore, it appears that the slight decrease in efficiency observed for some of the slurries is related to the additional friction at the piston/ring cylinder liner interface when firing coal/water slurry fuels, rather than any differences in combustion. The engine wear, particularly at the piston ring/cylinder liner interface, is considerably greater than that which occurs with liquid fuels. However, it is concluded that by means of technological advances in materials, design changes and new lubrication concepts, are reliable and economical coal/water slurry slow speed engine could be developed.
