It also introduces analysis of thermal performance, fuel combustion issues, performance monitoring and improvement, health monitoring, economics of operation and maintenance, and environmental aspects, among other thermal power plant related issues. The book contains 12 chapters, divided into four parts. The first part introduces performance monitoring, in addition to modelling and improvement, which includes green power generation from fossil fuelled power plants. This section introduces the concept of solar aided power generation (SAPG) in conventional coal fired power plants. The answer on how solar thermal energy can be integrated into fossil (coal) based power generation cycles to produce green power is presented and discussed in this part. It has been noted that the efficiency of SAPG is higher than that of either solar thermal or conventional fuel fired power plants. In general, the power sector is facing a number of critical issues. However, the most fundamental challenge is meeting the growing power demand in sustainable and efficient ways. How the plant process can be monitored and modelled to improve plant efficiency is also presented in this part. The second part discusses fuel combustion issues. Efficient combustion leads to the reduction in emissions and an increase in plant efficiency. Ignition properties are therefore fundamental combustion performance parameters for engineering design of combustion processes. This part discusses pulverized fuel combustion processes, mild combustion, its importance and its simulation, determination of coal ignition properties, and understanding of engineering design of power plants versus efficient fuel combustion. The third part presents functional analysis and health monitoring of power plants, including component faults diagnosis and prognosis. A diagnostic engine performance model is the main tool that identifies the faulty engine component. Furthermore, functional analysis is important for the design of supervisory control systems for power plants, while the development of an expert system is necessary for managing load shedding. This part presents application of functional analysis, X Preface supervisory control of power plants, component fault diagnosis and prognosis, application of blade-tip sensors for plant health monitoring, and expert system for managing the event of load shedding. Lastly, the fourth section presents economic and environmental aspects of power plants. Economic analysis and consideration of environmental issues are essential for the decision making process of any new project. This part presents financial aspects and life cycle analysis of power plants, factors affecting decision making, importance of using heat resistant metals in power plants, and environmental aspects such as carbon dioxide (CO2) emissions, corrosion inhibitors in the cooling water system, water pollution, etc. I would like to express my sincere gratitude to all of the authors for their high quality contributions. The successful completion of this book has been the result of the cooperation of many people. In the end, I would like to thank the Publishing Process Managers Mr. Jan Hyrat and Ms. Martina Durovic for their support during the publishing process, as well as Ms. Viktorija Zgela for inviting me to be the editor of this book.
