Combined Heat and Power (CHP) is the sequential or simultaneous generation of multiple forms of useful energy (usually mechanical and thermal) in a single, integrated system. CHP systems consist of a number of individual components-prime mover (heat engine), generator, heat recovery, and electrical interconnection-configured into an integrated whole. This book reviews the technical and economic characterisation of biomass resources, biomass preparation, energy conversion technologies, power production systems, and complete integrated systems.
