Book excerpt: In this test program, four military engines and a gas turbine combustor were run to determine the effects of fuel properties on combustion performance. During this program, 18 test fuels were prepared with properties extending beyond the range of the specifications of diesel fuels. Diesel engine performance data were analyzed statistically, and regression equations were obtained for each engine expressing load in terms of speed, energy input, cetane number, kinematic viscosity, 10-percent boiling point, and aromatic content. Combustion performance measurements in the T-63 gas turbine combustor included flame radiation, exhaust smoke, gaseous emissions (THC, CO and NOx), combustion efficiency, and ignition properties. The atomizing characteristics of the test fuels were examined with a particle sizing system based on forward-angle diffraction, and the results were correlated with the ignition properties of the fuels. Flame radiation and exhaust smoke were correlated with H/C ratio of the fuel. Viscosity and end point work were used as correlating parameters for THC and CO emissions, and combustion efficiency. Significance of the results was discussed, and recommendations for further testing was presented.

Available in PDF, EPUB and Kindle. Book excerpt: The effects of a wide variety of fuel types on the gaseous exhaust emissions, smoke, and particulates and on the combustor wall temperatures of a small industrial gas turbine engine are presented. The results were determined from evaluation tests conducted with the use of a single-shaft, constant-speed engine, rated at 534 kW, which employs a single, can-type combustor. The test fuels included a pure hydrocarbon, aviation gasoline, jet fuels, diesel fuel, fuel oils, an experimental broad-specification fuel, and a coal-derived fuel from the solvent-refined coal II (SRC-II) process. The hydrogen content of the fuels ranged from 9.1 to 16.1% by weight. Decreasing the fuel hydrogen content increased smoke emissions and combustor wall temperatures. The relationship between the mass concentration of exhaust particulates and the smoke number was similar for the coal-derived SRC-II and petroleum-based fuels. The combustion efficiency, determined from exhaust hydrocarbon and carbon monoxide emissions, did not change appreciably at any load condition for a wide range of fuel properties. The conversion of fuel-bound nitrogen to exhaust nitrogen oxides (NOx) was found to depend on the fuel nitrogen content and engine load. The conversion efficiencies were similar for the coal liquid, which was naturally high in fuel-bound nitrogen, and an artificially doped petroleum fuel.

Book excerpt: The objective of this study was to develop and/or improve correlations of fuel properties and engine design with combustion performance and hot section durability. The data base consisted primarily of fuel effect data obtained over the past four years under a number of DoD contracts. The approach taken was first to develop fuel effect correlations for specific combustor configurations, then to tie together these correlations using engine design parameters thereby allowing prediction of fuel effects in any current or future aircraft gas turbine combustion system. In most cases statistical analysis was used to identify the correlating variables. The relationships developed for individual combustors were then correlated with combustor design and operating parameters that were influence by fuel differences.

Available in PDF, EPUB and Kindle. Book excerpt: Results of an analytical and experimental program to determine the effects of broad variations in fuel properties on the performance, emissions, and durability of several prominent turbojet engine combustion systems, including both turbo-annular and annular configurations, are presented. Measurements of mean drop size conducted at representative engine operating conditions are used to supplement the available experimental data on the effects of combustor design parameters, combustor operating conditions and fuel type, on combustion efficiency, lean blowout limits, lean lightoff limits,liner wall temperatures, pattern factor, and pollutant emissions. The results of the study indicate that the fuel's physical properties that govern atomization quality and evaporation rates strongly affect combustion efficiency, weak extinction limits, and lean lightoff limits. The influence of fuel chemistry on these performance parameters is quite small. Analysis of the experimental data shows that fuel chemistry has a significant effect on flame emissivity, flame radiation, and liner wall temperature, but its influence on the emissions of carbon monoxide, unburned hydrocarbons, and oxides of nitrogen, is small. Smoke emissions are found to be strongly dependent on combustion pressure, primary-zone fuel/air ratio, and the mode of fuel injection (pressure atomization or airblast). Fuel chemistry, as indicated by hydrogen content, is also important.

Available in PDF, EPUB and Kindle. Book excerpt: Reflecting the developments in gas turbine combustion technology that have occurred in the last decade, Gas Turbine Combustion: Alternative Fuels and Emissions, Third Edition provides an up-to-date design manual and research reference on the design, manufacture, and operation of gas turbine combustors in applications ranging from aeronautical to power generation. Essentially self-contained, the book only requires a moderate amount of prior knowledge of physics and chemistry. In response to the fluctuating cost and environmental effects of petroleum fuel, this third edition includes a new chapter on alternative fuels. This chapter presents the physical and chemical properties of conventional (petroleum-based) liquid and gaseous fuels for gas turbines; reviews the properties of alternative (synthetic) fuels and conventional-alternative fuel blends; and describes the influence of these different fuels and their blends on combustor performance, design, and emissions. It also discusses the special requirements of aircraft fuels and the problems encountered with fuels for industrial gas turbines. In the updated chapter on emissions, the authors highlight the quest for higher fuel efficiency and reducing carbon dioxide emissions as well as the regulations involved. Continuing to offer detailed coverage of multifuel capabilities, flame flashback, high off-design combustion efficiency, and liner failure studies, this best-selling book is the premier guide to gas turbine combustion technology. This edition retains the style that made its predecessors so popular while updating the material to reflect the technology of the twenty-first century.

Available in PDF, EPUB and Kindle. Book excerpt: Two combustor rigs have been used to study the sensitivities of combustor operation to the physical and chemical properties of fuels. Eighteen fuels including synfuels were used to accentuate the properties of concern: composition, viscosity, and boiling-point distribution. Flame radiation and smoke were best correlated by hydrogen content rather than hydrocarbon structure; the soot formation was due to gas-phase reactions. Lean-blowout conditions were about the same for all fuels except that gasoline could be burned leaner at idle conditions. Ignition limits were more sensitive to volatility than viscosity. Gaseous emissions and combustion efficiency were not significantly affected by fuel properties although some sensitivity to boiling point distribution was evident. In all performance areas, the syncrude fuels correlated in the same ways as the petroleum-derived fuels except fo the NOx emissions from the nitrogen containing shale oil fuel. (Author).

Book excerpt: Engines now in production or under development were designed for satisfactory performance and life on current specification fuels; many of these engines may not be able to handle the stress implied by a broadened fuel specification. Among the fuel properties of greatest concern to turbine engine combustion are the aromatic content, the distillation curve, and the viscosity. Fuel bound nitrogen is one new property which has emerged from the use of syncrude fuels because of additional NOx found in the exhaust.

Book excerpt: Industrial Gas Turbines: Performance and Operability explains important aspects of gas turbine performance such as performance deterioration, service life and engine emissions. Traditionally, gas turbine performance has been taught from a design perspective with insufficient attention paid to the operational issues of a specific site. Operators are not always sufficiently familiar with engine performance issues to resolve operational problems and optimise performance.Industrial Gas Turbines: Performance and Operability discusses the key factors determining the performance of compressors, turbines, combustion and engine controls. An accompanying engine simulator CD illustrates gas turbine performance from the perspective of the operator, building on the concepts discussed in the text. The simulator is effectively a virtual engine and can be subjected to operating conditions that would be dangerous and damaging to an engine in real-life conditions. It also deals with issues of engine deterioration, emissions and turbine life. The combined use of text and simulators is designed to allow the reader to better understand and optimise gas turbine operation. Discusses the key factors in determining the perfomance of compressors, turbines, combustion and engine controls Explains important aspects of gas and turbine perfomance such as service life and engine emissions Accompanied by CD illustrating gas turbine performance, building on the concepts discussed in the text
