GE Transportation Systems, manufacturer of diesel-electric locomotives, has been pioneering the development of a coal fired diesel engine. The project is the consequence of the 1982 study to find the most effective way to reintroduce coal as a locomotive fuel, to alleviate high fuel costs and unavailability. The project which was initially sponsored by two American railroads has since been funded largely by the U.S. Department of Energy. Feasibility of using a coal water slurry has been demonstrated and preliminary test results for commercial practicality are most encouraging. Engine thermal efficiencies are comparable to oil engines and materials have been identified to withstand the erosive effects of the fuel and its combustion products. The presence of the water in the fuel has a significant effect in controlling NOx emissions, HC and CO emissions are very low and particulates can be controlled with a particulate trap. Economic studies indicate coal slurry fuel is an attractive economic alternative for railroads. A 2200 KW engine is scheduled to be installed on a locomotive this year. The success of this project may influence the development of coal burning diesels of this power output and high for utilities.
