An FT4A-9 engine test was run at Long Island Lighting Company (LILCO), and a selected single-can combustor from the LILCO engine was run at United Technologies Research Center (UTRC). Performance and emission tests were run with No. 2 petroleum distillate fuel and hydrotreated Paraho shale oil residual, with and without water injection. The engine operated successfully with low smoke when running on shale oil residual and No. 2 petroleum distillate fuel. The use of hot water injection was successfully demonstrated with reduced NO/sub x/ emissions when operating on both fuels. The Environmental Protection Agency (EPA) NO/sub x/ limit of 75 ppM for nitrogen free fuel, corrected to 15% oxygen, was easily met at a water-to-fuel ratio of 0.38 with No. 2 petroleum distillate fuel. The limit of 125 ppM for fuels containing 0.25% nitrogen or greater was close to being met at 18.5 MW with shale oil residual at a water-to-fuel ratio of 0.79. Post-test engine inspection showed that all combustor components, including turbine inlet vanes, were in good condition. NO/sub x/ emissions from single-can combustor testing with both fuels exceeded engine levels. Carbon monoxide and unburned hydrocarbons were slightly lower. These differences appear to be due to the placement of the gas sampling probes in the single-can tests. Smoke levels were low and NO/sub x/ reduction trends with water injection were comparable to engine results.
