Book excerpt: The mechanism of formation of sulphur trioxide in combustion gases has been investigated using liquid fuel firing combustor with laminar pre-mixed flame. The combustion chamber was constructed from a stainless steel tube for minimizing any affect of catalysis. A temperature controlled evaporating chamber was designed where liquid fuel was evaporated and mixed with total combustion air prior to entering the combustion zone. The vapour mixture then passed through a silica sintered disc and a flat flame was produced. Six sampling ports at 0.304m (1 ft) intervals along the combustion tube were used for sampling the gases for analysis and for the measurement of sulphur trioxide with respect to residence time. Diesel oil, Kerosine, Cyclohexane, n-hexane, and n-Pentane were used in the investigation: Sulphur content of these fuels were raised to 3.4% (wt.) by addition of appropriate amount of carbon disulphide (CS2) in each fuel. It was found that SO3 was only formed when there was an excess oxygen in the combustion gases and under sub-stoichiometric conditions, no SO3 could be detected. An increase in the quantity of combustion air in excess of stoichiometric requirement lead to an increase in the concentration of SO3 in the combustion gases. However, the level of SO3 content in the flue gases reached a maximum at about 4% excess oxygen concentration in the flue gases. It was established that ignition properties of fuels have an effect on the oxidation of S02. Ignition delay v temperature curves for the fuels employed in the research programme were determined. This was done with the help of Ignition-Delay apparatus (PART II). It was found that fuels having shorter ignition delay times at. temperatures. prevailing near flame zone produced less SO3 under identical combustion conditions. The results of the effect of residence time of combustion gases in the high temperature zone showed that in the first instance amount of SO3 formed was in excess of those predicted from thermodynamic considerations involving molecular oxygen. Sulphur trioxide thus formed began to dissociate back into sulphur dioxide and oxygen as the gases continued to pass along the combustion chamber. It was thought that oxygen atoms, produced in the flame, being a reactive oxidising species are responsible for the oxidation of SO2. The theory proposed to explain the experimental results appear to be that of a consecutive reaction [see full text for details].

Book excerpt: Liquid Fuels discusses the properties, classification, manufacturing, and practical use of liquid fuels. The book is organized into 10 chapters discussing the various aspects of liquid fuels, from source to storage. Chapters 1 and 2 present the main source of liquid fuels and other sources such as oil shales and coal. Chapter 3 illustrates the physical and chemical tests used to determine the properties of liquid fuels and the significance of these properties to the practical applications of the different types of fuels. Fuels for spark and compression ignition engines are discussed in Chapters 4 and 5. Chapter 6 presents the combustion and atomization of fuel oils. Chapters 7 to 9 enumerate the industrial and household uses of liquid fuels. The final chapter deals with the handling and storage of liquid fuels. Students of chemical engineering and metallurgy and people working at industries requiring the use of liquid fuels in their manufacturing processes will find the book useful.

This book was released on 1980 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: High temperature corrosion, at 730? C, by combustion gases produced by burning liquid fuels in a laboratory combustor has been investigated. A selected range of steels and alloys (mild steel, stainless steel type 347, Nimonic N90, N105, and IN657) have been tested in the combustion gases using fuels containing varying amounts of impurities in the range of 0 - 6% sulphur, 0 - 60 ppm sodium, and 0 - 300 ppm vanadium. On the basis of the comprehensive results a computer programme was written to predict corrosion rates of mild steel by combustion gases produced by burning fuels containing impurities such as sulphur, sodium and vanadium. The programme was tested, and the predictions which included the change of fuel were experimentally verified. Oil soluble additives have been used to show the effect on corrosion rates of the materials tested. By using X-ray diffraction analysis of the oxide layers, and with the help of electron microscopy, an attempt was made to investigate the mechanism of corrosion in the individual and collective presence of sulphur, sodium and vanadium-supplied by the test fuels. It is shown, for example, that the presence of sulphur in the fuel helps in the formation of FeO in the surface oxide layers. The ignition delay time or simply the ignition delay, which is the time lapse between the introduction of a fuel droplet into a heated atmosphere and its eventual ignition, was measured for all the test fuels. It is shown that the addition of elemental impurities such as sulphur sodium and vanadium have no significant effect on the ignition delay of the fuel but the addition of oil soluble additive makes the, ignition delay - temperature, curve steeper at the operating temperature and also reduces, corrosion of materials. Light hydrocarbon fuels having lower ignition delay than Kerosene at the operating temperature can be used as an additive to reduce the formation of sulphur trioxide in the combustion gases.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents an analysis of the results of studies of motor fuels ageing, conducted in laboratory and model conditions, in terms of building a system operating on-line, allowing continuous assessment of the operational usability of gasoline and diesel fuels, including those containing the addition of ethanol and FAME, respectively. This research was carried out in the framework of the project: "A system for the continuous control of the degree and rate of the liquid fuels ageing process during storage, which received co-funding from the European Regional Development Fund under the Operational Programme "Innovative Economy". The book presents an evaluation of the impact of fuel production processes on its stability and an analysis of changes in normative parameters of fuels during their storage and use. The book presents also the results of tests on the corrosive effects of fuels during storage processes. This project was co-financed by the European Regional Development Fund under the Operational Programme "Innovative Economy".

Available in PDF, EPUB and Kindle. Book excerpt: This book is concerned with providing a fundamental basis for understanding the alloy-gas oxidation and corrosion reactions observed in practice and in the laboratory. Starting with a review of the enabling thermodynamic and kinetic theory, it analyzes reacting systems of increasing complexity. It considers in turn corrosion of a pure metal by a single oxidant and by multi-oxidant gases, followed by corrosion of alloys producing a single oxide then multiple reaction products. The concept of “diffusion paths is used in describing the distribution of products in reacting systems, and diffusion data is used to predict reaction rates whenever possible. Provides a logical and expert treatment of the subject for use as a guide for advanced-level academics, researchers and practitioners Text is well supported by numerous micrographs, phase diagrams and tabulations of relevant thermodynamic and kinetic data Combines physical chemistry and materials science methodologies
