Book Description
Our interest in Mulhouse for carbon black and soot began some 30 years ago when J.B. Donnet developed the concept of surface chemistry of carbon and its involvement in interactions with gas, liquid and solid phases. In the late sixties, we began to study soot formation in pyrolytic systems and later on in flames. The idea of organ1z1ng a meeting on soot formation originated some four or five years ago, through discussions among Professor J.B. Howard, Dr. A. D'Alessio and ourselves. At that time the scientific community was becoming aware of the necessity to strictly control soot formation and emission. Being involved in the study of surface properties of carbon black as well as of formation of soot, we realized that the combustion community was not always fully aware of the progress made by the physical-chemists on carbon black. Reciprocally, the carbon specialists were often ignoring the research carried out on soot in flames. One objective of this workshop was to stimulate discussions between these two scientific communities. During the preparation of the meeting, and especially during the review process by the Material Science Committee of the Scientific Affairs Division of N.A.T.O. the toxicological aspect emerged as being an important component to be addressed during the workshop. To reflect these preoccupations we invited biologists, physical chemists and engineers, all leaders in their field. The final programme is a compromise of the different aspects of the subject and was divided in five sessions.

Book Description
Industry relies heavily on the combustion process. The already high demand for energy, primarily from combustion, is expected to continue to rapidly increase. Yet, the information is scattered and incomplete, with very little attention paid to the overall combustion system. Designed for practicing engineers, Heat Transfer in Industrial Combustion e

Book Description
During combustion of fossil fuels soot particles form as a by-product when a sufficient amount of oxygen is not present to yield a complete conversion of fuel into major combustion products such as carbon dioxide and water vapour. The soot particles (unburnt carbon) significantly affect the performance and durability of many engineering systems such as gas turbines and diesel engines and are the cause of significant human health problems associated with the respiratory system. Environmentally, the emissions of soot particles from combustion systems are also harmful as they contribute to the global warming. This book covers the important technological issues related to the formation, nanostructure, modelling, health effects, reduction and impact of soots.

Book Description
Combustion technology has traditionally been dominated by air/fuel combustion. However, two developments have increased the significance of oxygen-enhanced combustion-new technologies that produce oxygen less expensively and the increased importance of environmental regulations. Advantages of oxygen-enhanced combustion include less pollutant emissi

Book Description
The physical and chemical properties of soot particles generated by an acetylene-air, premixed flame stabilized on a well-characterized, water cooled, porous, flat flame burner are analyzed over a wide range of operating parameters. To characterize the soot generated in combustion systems as a function of combustion parameters, the temperature, velocity, and burner heat losses are measured over the stable range of burner operation. The flat flame achieved with this burner is uniform in temperature over the entire flame disk within a few percent of the maximum flame temperature. In separate experiments, hot film indicates that the cold flow gas velocity assessment is uniform within approximately 10% over the entire porous disk. Particle size distribution measurements by an Electrical Aerosol Size Analyzer indicate two submicron modes, one centered at approximately 80 A and another which occurs only in luminous flames at high equivalence ratios at approximately 500 A. The chemical composition of soot collected on different filter media is determined by X-ray photoelectron spectroscopy (ESCA) and X-ray fluorescent techniques. Two oxygenated species, as yet unidentified but here designated as O/sub I/ and O/sub II/, adsorbed on carbon particles, are recognized. The ratios of atomic concentrations O/C and O/sub I//O/sub II/ are determined as a function of flame parameters. These ratios decrease as the flame equivalence ratio increases but remain constant at equivalence ratios greater than 2.0. The rate of heterogeneous oxidation of SO2 in a plume containing combustion-generated carbon particles is also studied. Water vapor and oxygen concentrations along with particle size and concentration are found to have controlling influences on the oxidation of SO2. An analysis is presented in which integrated forms of species, momentum, and energy equations are solved to predict concentration histories along the trajectory of a reacting plume of combustion products.

Book Description
The public health risks posed by automotive particulate emissions are well known. Such particles are sufficiently small to reach the deepest regions of the lungs; and moreover act as carriers for many potentially toxic substances. Historically, diesel engines have been singled out in this regard, but recent research shows the need to consider particulate emissions from gasoline engines as well. Already implicated in more than one respiratory disease, the strongest evidence in recent times points to particle-mediated cardiovascular disorders (strokes and heart attacks). Accordingly, legislation limiting particulate emissions is becoming increasingly stringent, placing great pressure on the automotive industry to produce cleaner vehicles - pressure only heightened by the ever-increasing number of cars on our roads. Particulate Emissions from Vehicles addresses a field of increased international interest and research activity; discusses the impact of new legislation globally on the automotive industry; and explains new ways of measuring particle size, number and composition that are currently under development. The expert analysis and summary of the state-of-the-art, which encompasses the key areas of combustion performance, measurement techniques and toxicology, will appeal to R&D practitioners and engineers working in the automotive industry and related mechanical fields, as well as postgraduate students and researchers of engine technology, air pollution and life/ environmental science. The public health aspects will also appeal to the biomedical research community.

Book Description
Based on papers delivered at the First International Congress on Toxic Combustion By-products: Formation and Control, held in Los Angeles, Calif., August 1989. An overview of emissions, health risks, and existing regulations is followed by coverage of such topics as continuous emissions monitoring and control, processing of solids and liquids, fundamental chemistry, metals emissions, gas transport, and advanced combustion and control systems. Despite the length of time between the conference and publication, no index was prepared. Annotation copyright by Book News, Inc., Portland, OR
