ECONOMIC AND TECHNICAL ASSESSMENT OF DIESEL ENGINES USING COAL-BASED FUELS FOR ELECTRIC POWER GENERATION

The slow-speed, two-stroke diesel engine operating on coal-based fuels is a promising power conversion system for electric power generating plants and for industrial cogeneration applications. The coal-based diesel system is a near-term technology which can encourage the use of coal fuels and achieve substantial energy savings. This report describes: experimental engine performance data on representative coal-based fuels, economics of typical system installations, and development requirements to make the system commercially available. The program results indicate that current slow-speed, two-stroke diesel engine technology can be adapted, with minimum development, for coal-derived liquid fuels in order to establish an efficient power system with multifuel capabilities and wide applicability. Engine test results on two coal-derived liquid fuels (COED and SRC-II) are included in this report. The slow-speed, two-stroke diesel engine performs very well on both fuels. The results of continuing tests on micronized coal/oil slurry will be reported in a separate document. Preliminary results of the slurry tests indicate that coal in the form of micronized particles is also a satisfactory fuel for the slow-speed, two-stroke diesel engine if adequate provisions are made for fuel injection and ash related wear.
