Comparative Testing of Petroleum Surrogate Fuels With Coal-Derived Liquids in a Combustion Turbine Burner

Abstract

Tests have been made in a combustion turbine burner using six petroleum-derived surrogate (PDS) fuels simulating six coal-derived liquid (DCL) fuels tested earlier. The purpose being to examine their suitability for use in place of scarce CDL fuels for combustor development. The PDS and DCL fuels were matched in terms of aromaticity and fuel bound nitrogen although differences in viscosity, distillation range and constituent species existed. In three cases, the low fuel bound nitrogen present in the PDS fuels was made equal to their coal liquid counterparts via the addition of quinoline. All six PDS fuels were evaluated on a 0. 14-m-dia combustor while one of the surrogate fuels was evaluated on a 0.3-m-dia Westinghouse commercial combustor.nitrogen content while combustor wall temperature and smoke are related to hydrogen deficiency (i.e., aromaticity) of the CDL fuels. For both the PDS and CDL fuels, aromaticity is defined as the percentage of aromatic carbon atoms in the fuel relative to the

“…A comparison of the data obtained during these tests and that calculated based on Ref. 3 shown in Fig. 11 show that large differences exist as FBN content increases.…”

“…Copies will be available until December 1, 1980. As was described in Part I of this paper, one program objective was to determine the suitability of petroleum derived surrogate (PDS) fuels for the development of combustors for CDL fuels. The results of the full scale test of one such surrogate (for light H-coal) are discussed in the previously mentioned paper by Singh, et al (6).…”

“…Aromaticity and nitrogen content were the key parameters utilized in matching the CDL and PDS fuels with secondary emphasis placed on gravity, boiling range and viscosity. The results of testing with these surrogates is the subject of another paper by Singh, et at (1).…”
