A Chapter-by-Chapter Overview Chapter One is intended to be useful to anyone interested in wood-chip systems. Its opening sections (”Who Should Read This Guide?” and “What Kinds of Facilities Use Biomass?”) describe the kinds of settings for which wood-chip systems are appropriate and the people at those facilities who might benefi t from this book. The next section looks at the reasons for considering a wood-chip system. The next section gives an introduction to the sources of biomass fuel. The fi nal section (”What Does a Wood-Chip System Look Like?”) briefl y describes the appearance and function of a wood-chip heating plant. Readers who want an overview of wood-chip systems might skim Chapter Two, dealing with wood chips and other biomass fuels, and Chapter Three, which lists in detail the components of a wood-chip system. Decision-makers for facilities might spend more time with Chapters Seven and Nine to learn about analyzing the cost-effectiveness of a wood-chip system and fi nding capital to fi nance the installation. Chapter Eight gives useful information on sources for technical and professional assistance. Chapter Ten covers a variety of topics of interest to both lay decision-makers and technically oriented participants. Decision-makers and owners will fi nd information here on putting together the pieces of a wood-chip system project, including the role of technical and professional resource people. The message on “The Importance of the System Operator” (page 57) is important for all readers. A section of Chapter Ten, “Public Involvement, Public Education,” is meant to assist anyone who will interact with the public in proposing a wood-chip heating system. See in particular “Commonly Asked Questions About Burning Wood Chips” on page 58. The information in Chapter Eleven, “Operating and Maintaining a Wood-Chip System,” will help the owners, managers, or operators of any installation. Along with the installation and fi rst-year operation of a new system, this chapter covers ongoing issues related to maintaining and monitoring a system’s performance. Some chapters are intended in particular for readers who are concerned with the technical details of a wood-chip system. For example, the mechanical engineer hired to oversee the selection and installation of a chip system will benefit from a careful reading of all the technical sections, including Chapter Three on system components, Chapter Four on system efficiency, Chapter Five on emissions, Chapter Six on types of automatic wood combustion systems, and parts of Chapter Ten on implementing a wood-chip system project. The sections of Chapter Ten on performance specifi cations (page 61) and system sizing (page 62) will be especially useful to those responsible for specifying the wood-chip system during the process of selecting a manufacturer. Chapter Twelve takes a speculative look at the future of biomass. This concluding chapter is intended to give the reader an idea of the larger world of the biomass resource and its possible future uses.
