摘　　要：针对1000MW超超临界锅炉制粉系统存在的一次风管积粉、煤粉中含有大颗粒的问题,进行详细分析研究,通过改进粗粉分离器结构、调整分离器挡板位置、提高一次风量、制粉系统热态调平等措施,解决了以上问题,大大提高了锅炉运行的安全性和经济性。Aiming at the problems occurring in coal pulverizing system of a 1000MW ultra-supercritical boiler, such as pulverized-coal deposition in primary-air tubes and more big particles inside pulverized-coal, detail analysis is made and further measures are put forward. Through improving construction of classifier, adjusting position of classifier＇s vanes, increasing mass flow of primary air and uniforming velocities in primary air tubes at hot status, the problems are solved and boiler＇s safety and economics increases greatly.
