Analysis of the Faulty of Steam Turbine Pressure Limiting Control Mode Switch Initial Pressure Control Mode During the Auxiliary Equipment Failure Run Back Process
During the RB process of a coal mill in a domestic factory,the turbine pressure limiting mode failed to switch to the initial pressure mode,resulting in the failure of the RB test.The article introduces the main functions of RB,explores the control strategy of SAIC DEH main steam pressure in the Ruiwo DCS system,analyzes the process of switching from pressure limiting mode to initial pressure mode,and combines the switching principle to analyze the reasons for the failure of coal mill RB.It summarizes the problems of this switching method in specific situations and proposes corresponding optimization suggestions.
