A field test, Evaluation of Coal Liquids as Utility Combustion Turbine Fuels, was performed to evaluate the suitability of H-Coal and EDS middle distillate coal derived liquid (CDL) as utility combustion turbine fuels. A Westinghouse W251AA 26 MW/sub e/ combustion turbine operated by the Philadelphia Electric Company was the test engine. No. 2 petroleum distillate fuel was also fired to establish baseline data. Site modifications include a temporary synfuel storage and fuel transfer system, water storage and injection equipment, an instrumented combustor, engine and emissions intrumentation and data acquisition systems, and industrial hygiene facilities required for the proper handling of the CDLs. The overall results of testing were positive for using such CDL fuels in combustion turbines for power generation. With the exception of higher combustor metal temperatures and persistent fuel filter plugging with the EDS fuel, the engine operated satisfactorily during approximately 80 hours of total running over the standard range of load and water injection conditions. The engine power output and heat rate performance characteristics were essentially unaffected. The emissions signatures of the two CDL fuels were as expected. The combustor dynamic response indicated no significant effect of operation with the CDL fuels. Combustor metal temperature increased with the CDL fuels because of the brighter flame associated with decreased hydrogen content and decreased with water injection. Good correlation of a dimensionless metal temperature parameter with fuel hydrogen content was obtained. With the one exception of unexpectedly high FBN conversion for EDS, the emissions and combustor metal temperature results of this field test compared well with the earlier laboratory test results for similar fuels under RP989-1. 9 references, 75 figures, 56 tables.
