Abstract:

Energy plays an increasingly significant role in the development of modern society and economy. China's resource characteristics determine that coal-fired power generation will occupy a dominant position in energy system for a long time. Large-capacity and high-parameter coal-fired power generation system is one of the most feasible technical approaches to realize coal energy clean and efficient utilization and the most important way to ensure the national power supply. Coal-fired power generation system in China is under the background of energy structure change and the parameters of the double demand theory and technology. This paper summarizes the research progress of new theories and methods for efficient and clean operation of high-parameter coal-fired generating units in key unit, process and system integration. Therefore, coal-fired generating units can generate electricity efficiently and achieve ultra-low emission of pollutants.

Key words: energy, coal-fired power generation, clean and efficient utilization, ultra-supercritical boiler, key units, system integration
