In order to facilitate the isolation and maintenance of the AQC boiler from the cement production line during operation,large-sized high-temperature resistant double rack gate valves were installed on the inlet and outlet flue of the AQC boiler in a certain cement kiln waste heat power plant due to its large size,high flue gas temperature,and high ash content.During the trial operation of the gate valve equipment,problems such as insufficient output of the driving device,damage to the transmission components,and blockage of the gate valve occurred.It elaborates on the cause analysis and technical improvement plans of the gate valve equipment related problems,analyzes how the gate valve equipment can adapt to high-temperature and high ash flue gas environments,and provides a solution through practical engineering applications.
