Cogeneration from Waste Energy Streams Four Energy Conversion Systems Described

In times of rapid growth in the costs of energy of all types, renewed interest comes for cogeneration. Specifically, the recovery of waste energy has become economical and the potential for growth of cogeneration systems to utilize waste heat is high. Cogeneration systems for bottoming cycles and waste energy recovery from process streams are described. The nature of the energy to be recovered and the number of quads in various temperature zones are identified. Several. rankine cogeneration systems are described and the sensitivity to the cost of fossil fuel is covered. The concept of power modules is provided as the best approach to economical installation in various industries where the mass flow and Btu count of waste streams are sufficient to provide energy for cogeneration.
