Title: Development of a coal/water-slurry-fueled diesel engine for industrial cogeneration: Task 4. 0, Single-cylinder engine tests

Technical Report ·
OSTI ID:6233617

Purpose of the program is 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. This report covers the results obtained in Task 4.0, Engine Test, in which four micronized and beneficiated coal/water slurries were utilized as a fuel in a single-cylinder version of the slow-speed, two-stroke diesel engine. Thermal performance, emissions and engine wear are reported on and evaluated in this report, based on the results of the testing program. The results of the program show that the slow-speed, two-stroke diesel engine can operate on coal/water slurry fuels at efficiencies approximately equal to those obtained with conventional liquid fuels and produces considerably lower amounts of exhaust emissions. 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 regarding cylinder liner and ring materials, design changes, and new concepts for the lubrication system, a reliable and economical coal/water slurry fired slow-speed engine can be developed.
