Combustion Effects of Coal Liquid and Other Synthetic Fuels in Gas Turbine Combustors: Part I — Fuels Used and Subscale Combustion Results

Abstract

Combustion tests on over twelve types of coal derived liquid fuels from the EDS, H-coal, SRC-I and SRC-II processes and three shale oil fuels have been conducted in gas turbine type combustors. Emission measurements were made of Nox, smoke, CO, and unburned hydrocarbons. Combustor wall temperature profiles were measured. The results are correlated with the fuel properties-percent nitrogen, hydrogen and aromaticity. This part of the paper discusses the fuels used in subscale combustion tests along with the test results. A companion paper (Part II) describes the results of full-scale combustor tests and a long term corrosion/deposition test.

“…This approach, which is the standard A reduction in the fuel hydrogen content or an increase in the aromatics has been shown (2) to produce an increase in flame radiation and a corresponding rise in the combustor wall temperature. Predictive techniques (3) indicate that a 4% reduction in hydrogen content will increase the primary zone inside surface temperature of the Lamilloy by approximately 150°F. The measured rise of the outer surface will be discussed in the following section.…”
