This book provides important insights into the combustion behavior of novel energy crops and agricultural fuels. It describes a new experimental approach to combustion evaluation, involving fundamental, bench-scale and commercial-scale studies. The studies presented were conducted on two representative biomass energy crops: a woody biomass poplar (Populus sp. or poplar) and an herbaceous biomass brassica (Brassica carinata or brassica). Moreover, agricultural residues of Manihot esculenta or cassava were also analyzed. The main accomplishments of this work are threefold. Firstly, it offers an extensive characterization of the above-mentioned fuels, their ash chemistry and their emissions of both solid particles and gaseous compounds that form at typical grate combustion conditions. Secondly, it presents an in-depth analysis of ash fractionation processes for major ash species. Thirdly, it describes the role of some critical and volatile key elements (K, Cl, S and P) in grate-fired combustion systems and elucidates the main differences in the ash chemistry during combustion of Si-rich and P-rich fuels. All in all, this work provides novel insights on the basic and fundamental mechanisms of biomass grate combustion with a special focus on ash transformation and highlights important issues and recommendations that need to be considered for an appropriate conversion of ash-rich fuels and for the development of future technology in the context of both small- and medium-scale biomass-based heat and power production.

The utilisation of biomass is increasingly important for low- or zero-carbon power generation. Developments in conventional power plant fuel flexibility allow for both direct biomass combustion and co-firing with fossil fuels, while the integration of advanced technologies facilitates conversion of a wide range of biomass feedstocks into more readily combustible fuel. Biomass combustion science, technology and engineering reviews the science and technology of biomass combustion, conversion and utilisation. Part one provides an introduction to biomass supply chains and feedstocks, and outlines the principles of biomass combustion for power generation. Chapters also describe the categorisation and preparation of biomass feedstocks for combustion and gasification. Part two goes on to explore biomass combustion and co-firing, including direct combustion of biomass, biomass co-firing and gasification, fast pyrolysis of biomass for the production of liquids and intermediate pyrolysis technologies. Largescale biomass combustion and biorefineries are then the focus of part three. Following an overview of large-scale biomass combustion plants, key engineering issues and plant operation are discussed, before the book concludes with a chapter looking at the role of biorefineries in increasing the value of the end-products of biomass conversion. With its distinguished editor and international team of expert contributors, Biomass combustion science, technology and engineering provides a clear overview of this important area for all power plant operators, industrial engineers, biomass researchers, process chemists and academics working in this field.

Progress in Biomass Conversion, Volume 4, reviews the state of knowledge and development in the biomass energy and chemicals field. When biomass is used for energy, it must be used in innovative systems that are both efficient and economically effective. Combining biomass with other fuel systems may be required, in addition to the more traditional approaches. New markets for biomass energy also may be required as well as recognition that biomass fuels are cleaner sources of energy. However, quantifying the environmental issues associated with biomass fuel utilization should not be overlooked. This book focuses on these major themes. It includes several chapters on the production of chemicals from various forms of biomass. It examines the optimal energy use of biomass and considers innovative methods for using biomass fuels, some of which should lead to new markets for biomass energy. Finally, it considers the important issue of the environmental consequences associated with the use of biomass fuels.

How much can technology contribute to securing adequate and affordable energy supplies and lower CO2 emissions? What energy technologies hold the most promise? How long will it take? At their 2005 summit in Gleneagles, G-8 leaders confronted these questions and called upon the International Energy Agency to provide advice on scenarios and strategies for a clean and secure energy future. This publication demonstrates how energy technologies can make a difference in a series of global scenarios to 2050. It reviews in detail the status and prospects of key energy technologies in electricity generation, buildings, industry and transport. It assesses ways the world can enhance energy security and contain growth in CO2 emissions by using a portfolio of current and emerging technologies (major strategic elements of a successful portfolio are energy efficiency, CO2 capture and storage, renewables and nuclear power). It provides technology and policy insights to help policy makers craft sustainable solutions.

Like coal and petroleum, biomass is a form of stored solar energy. The energy of the sun is "captured" through the process of photosynthesis in growing plants. Like all methods used to generate energy, the combustion of biomass generates pollution as a by-product. One advantage of biofuel in comparison to most other fuel types is that the energy within the biomass can be stored for an indefinite amount of time without any danger. Agricultural products specifically grown for use as biofuels include corn and soybeans, primarily in the United States, as well as flaxseed and rapeseed, primarily in Europe, and hemp is a growing crop around the world except for in America. Waste from industry, agriculture, forestry, and households can also be used to produce bioenergy; examples include straw, lumber, manure, sewage, garbage and food leftovers. Biomass used as fuel often consists of under-utilised types, like chaff and animal waste. Much research is currently in progress into the utilisation of microalgae as an energy source, with applications being developed for biodiesel, ethanol, methanol, methane, and even hydrogen. On the rise is use of hemp, although current politics restrains it. This book presents the latest leading edge research in a field set to explode with growth.
