| Abstract: | By making use of the redundance technique in control systems of ash conveying systems, its accuracy of signals is raised as well as the reliability and extensibility of the system. The system has a 3-level structure, including the administrative level, the control level and the on-site level. Actual operational results are extraordinarily satisfactory. |
