Operating Experience on Residual Fuel Oil With a W251 Combustion Turbine

Abstract

This paper describes the actual operating experience of a current technology combustion turbine, burning residual fuel, operating under actual utility conditions. The objective of the program was to demonstrate that combustion turbines utilizing air-cooled blades and vanes were capable of performing in an economical, reliable and satisfactory manner to meet the demands of a utility company in normal daily cyclical duty. Included in the program was an evaluation of a fuel treatment plant with associated fuel-handling requirements, resistance to corrosion of numerous blade and vane alloys both with and without protective coatings, plus optimization of a turbine cleaning system to remove turbine blade path deposition.

Thermophoresis—Enhanced Deposition Rates in Combustion Turbine Blade Passages

“…Fig. 3 also shows a preliminary deposition rate from field tests of a cooled, 35 MW turbine, running on residual oil [3]. These same tests supplied the output loss data shown on Fig.…”

“…Fig. 1 shows a comparison between the loss of output as a function of time in an uncooled, mid-1960's vintage [2] and a contemporary, cooled turbine [3]. Both machines were designed by the author's company and their blade paths are aerodynamically similar.…”

Impacts of low-pressure (LP) compressors’ fouling of a turbofan upon operational-effectiveness of a military aircraft

“…[14][15][16][17]. The result will be a deterioration in performance, which will become progressively worse with increasing operating time, unless appropriate maintenance occurs.…”
