通常沸腾床燃烧锅炉运行首先碰到的是点火启动问题。往往要经过多次试点火才能成功。其困难在于:整个床面应配风均匀;料层均匀并预热到适当的温度;启动风量需控制适当;启动过程中需防止低温熄火和高温结焦。电站采用容量较大的沸腾床燃烧锅炉时矛盾就更突出,一是床大,二是料多。随着容量增大,床面积增大(如一台130吨/时沸腾床燃烧锅炉主床面积就达38米~2),更加需要
The first thing that a fluidized bed combustion boiler usually runs into is the ignition start problem. Often after many trial fire to success. The difficulty lies in: the entire bed should be evenly distributed; uniform material and preheated to the appropriate temperature; start air volume to be properly controlled; start-up process to prevent low-temperature flameout and high temperature coke. The contradiction between the larger capacity of the fluidized bed combustion boiler and the power station is even more prominent. As the capacity increases, the bed area increases (such as a 130t / hour ebullated bed combustion boiler bed area of up to 38m ~ 2), more in need
