This book contains papers presented at the Engineering Foundation Conference on mineral matter in fuels held on November 2-7, 1997 in Kona, Hawaii. The conference is one of a continuing series that was initiated by the CEGB Mar- wood Engineering Laboratories in 1963. The conference was to be eventually organised by the Engineering Foundation as the need for multi-disciplinary work related to c- trolling ash effects in combustors became apparent. The conference covers both the science and the applications. The papers also present case histories, particularly for current fuel technologies, developments in advanced technologies for power generation and mathematical modelling of these processes. Developments since 1963 have been slow, but steady, due to the complexity of the chemical and physical processes involved. However, the research presented here displays great improvement in our understanding of the mechanisms by which mineral matter will influence fuel use. Steve Benson from EERC presented a review and current status of issues related to ash deposition in coal combustion and gasification. The application of new analytical tools, which have been detailed in the previous conferences, is presented. These include CCSEM, as well as new techniques for char- terising sintering of ash, such as TMA, image analysis, X-ray diffraction crystallography and thermal analysis. The new analytical techniques were extended to encompass widely differing fuels such as biomass. Ole H Larsen from ELSAM Denmark presented a review of these advanced techniques.

Combustion, the process of burning, is defined as a chemical reaction between a combustible reactant (the fuel) and an oxidizing agent (such as air) in order to produce heat and in most cases light while new chemical species (e.g., flue gas components) are formed. This book covers a gap on the market by providing a concise introduction to combustion. Most of the other books currently available are targeted towards the experienced users and contain too many details and/or contain knowledge at a fairly high level. This book provides a brief and clear overview of the combustion basics, suitable for beginners and then focuses on practical aspects, rather than theory, illustrated by a number of industrial applications as examples. The content is aimed to provide a general understanding of the various concepts, techniques and equipment for students at all level as well as practitioners with little or no prior experience in the field. The authors are all international experts in the field of combustion technology and adopt here a clear didactic style with many practical examples to cover the most common solid, liquid and gaseous fuels. The associated environmental impacts are also discussed so that readers can develop an understanding of the major issues and the options available for more sustainable combustion processes.

Combustion is very much an interdisciplinary topic, drawing together elements of chemistry, fluid mechanics and heat transfer. It is an ingredient in many undergraduate degree programmes, ranging from a pivotal role in fuel science through to a component part of courses in chemical, process and building services engineering. For many students in those disciplines where combustion in heating plant is an important part of their studies, there are often problems in coming to grips with the basic principles underlying the combustion of hydrocarbon fuels. In particular, the concepts of chemical and related thermodynamic changes can prove difficult to assimilate. The scientific literature dealing with combustion tends to be rather polarised, with a wealth of literature aimed at the specialist reader, but at a basic level the fundamentals of this important process are often treated rather tersely in textbooks on thermodynamics. The objective of this book is to provide an introduction to the basic principles of the combustion of hydrocarbon fuels in heating plant for buildings and industrial processes. In those chapters where practice in problem solving can make a positive contribution to understanding, some numerical problems have been included. Acknowledging the ever-widening use of computers in technical education, a number of algorithms which can be easily coded up for solving numerical problems have been incorporated in the text. These can prove particularly useful in, for example, the calculation of certain fluid properties, either for use in hand calculation or for incorporation into larger programs.

Nearly 3 billion people rely on solid fuels for their cooking and heating needs, classifying them as "energy poor". This poverty can be attributed to several factors, including a lack of resources (fuel), inefficient infrastructure (production and distribution), limited purchasing power (poverty), and ill-devised policies. Solid fuels, such as biomass, coal, and dung cakes, are burned in inefficient cookstoves. They generate products of incomplete combustion (PIC), such as CO, particulate matter (PM), and CH4, causing household air pollution (HAP) whose adverse impacts on both health and the environment have been well established. HAP causes diseases such as chronic obstructive pulmonary disorders (COPD), acute respiratory infections (ARI), tuberculosis, bladder and lung cancers, cataracts, and pneumonia. The World Health Organization has declared HAP to be the single largest environmental health hazard, accounting for 3.8 million deaths annually. Moreover, residential solid fuel combustion is a leading source of primary aerosols, which play important roles in atmospheric physics and chemistry, and affects regional and global climate with a net warming effect. To curb the adverse impacts of HAP, the United Nations has set a Sustainable Development Goal of eradicating energy poverty by 2030. Research on multiple fronts seeks to provide cleaner cooking energy by engineering either the cooking systems or the fuel. Developing more efficient solid fuel stoves, called improved cookstoves (ICS), has received the highest attention but the low adoption and still high emissions of ICS mean they alone will not eradicate energy poverty. This dissertation focuses on both options, i.e., ICS, and cleaner cooking fuel alternatives. Part 1 discusses the efficacy of current cookstove technology and the research needed to further advance the technology. Research on ICS is hampered by multiple concerns including a lack of fundamental research, real-time measurements to capture temporal variations, and high reliance on rules of thumb and experience. Extensive real-time physical and chemical characterization of pollutants from different ICS cookstoves was performed, and the effects of different operating conditions and fuel types were quantified. A 1-D steady-state model for a co-current moving bed reactor was integrated with a particle growth dynamic model to simulate combustion and pollutant formation in a top-lit updraft ICS. Field studies in India were conducted to explore how the cookstove and its surroundings interact and its subsequent effects on human health. Findings from the work done in Part 1 highlighted the need to look beyond the current metrics for assessing cookstove performance and regulating air quality. Moreover, cookstove combustion and emission characteristics change drastically with inevitable variations in operating parameters, which leads to inconsistent performance and personal exposure. Current ICSs are usually cleaner than traditional cookstoves, but still not close to the desired performance level. Therefore, cleaner fuel alternatives such as liquefied petroleum gas (LPG), natural gas, and electricity must be considered, though they require overcoming challenges such as resource constraints, affordability, accessibility, and policy. Part 2 focuses on understanding the intricate factors governing household fuel preferences via regional scale modelling and analysis from both the user's and provider's perspectives. This newly developed understanding will enable policymakers to target and manipulate the key factors governing household fuel preferences, and thus to promote adoption of cleaner fuel alternatives.
