Preface
Energy sources is the basis for developing economic, improving the living standards and making civilization progressing. Through the large-scale use of energy, human beings have met the needs of development of society and improvement of living standards. However, the pollutants discharged in the process of energy utilization(such as dust, sulfur dioxide, nitric oxide, hydrocarbon, microparticle and greenhouse gases) are rapidly destroying the ecological balance of the earth and the living environment of human beings.
Electric power industry is the basic industry of national economy, with the rapid development of social economic, the demand for electric power keeps increasing. As the basic equipment of energy conversion in thermal power plant, the power station boiler has undergone great changes in equipment and operation technology. The safety, economy, environmental protection property and the degree of automation have been improved continuously.
The use of large capacity and supercritical parameter in fire power generator is an effective way to improve the economic efficiency of generator set, which has been widely used by advanced countries, around the world, and China will also take the supercritical unit as a key to the construction of thermal power generating unit in the future. With the rapid development of national economy and the improvement of people's living standards, our electric power industry is also developing at an unprecedented speed, at present, a number of domestic supercritical units have been put into operation or under construction. This marks the manufacturing and operating levels of thermal power generation equipment has entered a new stage, therefore, accelerating the research on the key technologies in the manufacturing and operating the supercritical power units has become a realistic and glorious task for China's power workers.
前 言
能源是人类经济发展、生活水平提高、文明进步的基础。人类通过对能源的大规模的利用，满足了社会不断发展和生活水平不断提高的需要。但能源利用过程中排放的污染物（粉尘、二氧化硫、氧化氮，碳氢化合物、微颗粒、温室气体等）也正在急剧破坏着地球的生态平衡和人类自身的生存环境。
电力工业是国民经济的基础产业，随着社会经济的快速发展，电力需求不断增长。电厂锅炉作为火电厂能量转换的基础设备，在设备及运行技术方面也发生了巨大的变化。锅炉运行的安全性、经济性、环保性和自动化程度都得到了不断的改善。
火力发电机组采用大容量和超临界参数是提高发电机组经济性的有效途径，已经被世界先进国家所广泛采用，我国也将超临界机组作为今后一个时期火电机组建设的重点之一。随着国民经济的快速发展和人民生活水平的提高，我国电力工业也正在以前所未有的速度发展，目前，一批国产超临界机组已经投产或正在兴建。这标志着我国火力发电设备的制造和运行水平都进入了一个新阶段，因此加快研究超临界机组制造和运行中的关键技术也就成了我国动力工作者面临一项极具现实意义的光荣任务。
