This book is written by Dr. Hui Zhou as a Ph.D. dissertation in Tsinghua University, China. It establishes the thermochemical characteristics of model compounds in combustible solid waste (CSW), and delineates the influence of different factors on the thermochemical characteristics and the influence interactions between model components have on the thermochemical characteristics. The works provide a theoretical basis for the clean and high-efficiency utilization of CSW as well as the basic knowledge for further understanding the thermochemical conversion mechanisms of complex fuels. Researchers and engineers in the field of thermal engineering and environmental engineering can benefit from the book.
