Abstract: Focusing on an approach of solving two key problems of energy and environment simultaneously,the development of the polygeneration system combining chemical process with power process has been summarized,and a concept of generalized total energy system has been proposed. The concept of the generalized energy system extends clean-energy production and environmental control to the previous polygeneration, which emphasizes chemical products. Based on the principle of exergy, this paper introduces the principle of energy conversion in the novel system, and points out that cascade utilization of exergy between both chemical combustion process and thermal cycle process will make a breakthrough in improving energy efficiency and reducing environmental pollution. The generalized energy system also exploits a novel chemical-looping combustion system with no flame, for removing CO₂ and eliminating NO_x . The generalized energy system has significant impact on clean-energy production and greenhouse-gas control for its characteristics of high-efficiency, cleanliness, and flexibility.
