Energy Efficiency through Combined Heat and Power or Cogeneration 

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 new book reviews the technical and economic characterization of biomass resources, biomass preparation, energy conversion technologies, power production systems, and complete integrated systems.
