Abstract: The vacuity of the 2×150MW unit of the Sichuan Huadian Panzhihua Sanwei Power Generation Corporation Limited was lower, and this caused the safety and the economical efficiency of the unit operation to be decreased. The problems existed in the manufacturing, the installation, the commissioning and the operation of the unit and the factors causing the vacuity of the unit decreasing were analyzed. The relevant countermeasures were put forward, so it is ensured that the unit operates safely and economically under rational back pressure. 
