Thereinto , the coal mill equipment for power station is the dominant production of our company , including hp type middle speed coal mill , bbd type low speed tube ball mill and 9224 type gravimetric coal feeder with electronic weighing 其中电站磨煤制粉系统设备是我公司的主导产品，它包括hp系列碗式中速磨煤机、 bbd双进双出钢球磨煤机和9224型电子称重式给煤机等。
In the process of the actual unit plant design , the ways of the actual system , the running picture and the switch principle have been given . 3 . smith predictive method to solve the delay problem of feed - coal machine has been discussed , which has excellent effect 3 .为进一步解决单元机组运行过程中锅炉的慢特性，探讨了用smith -预估的方法来解决给煤机系统中的大迟延问题，取得了较好的效果。
In this paper , two 50t / h coal - fired boilers " burning control system of 26 # heating station was studied as its thesis , the primary pid controller was improved as its purpose , fuzzy control theory developed rapidly at present was applied as its means . the design scheme is that controlling transducers change rotate speed of supplying coal electromotor , fan , and blower using 8051 micro - controller . it realized computer control of burning process 本文以26 ~ #供热站的2台50t / h燃煤锅炉的燃烧控制为课题，以改进原有pid控制为目的，以当前发展比较迅速的模糊控制理论为手段，提出了采用8051单片机控制变频器改变给煤机、引风机和送风机转速的设计方案，实现了燃烧过程的计算机控制。
