On the occasion of the 76th anniversary of the founding of the People's Republic of China, the Afam II gas turbine power plant project in Rivers State, Nigeria, in which Yufeng Power Engineering Co., Ltd. participated, entered its final 72-hour reliability test. As of press time, all unit operating data are stable.

The Afam II gas turbine power plant project in Rivers State, Nigeria, is a significant energy project. It is a joint venture between Sahara Power Group, Africa's largest private power company, and Crescendough Nigeria Limited. The AFAM II gas turbine power plant project utilizes Alstom single-cycle technology and has an installed capacity of 180MW. The Alstom GT13E2 gas turbine is a classic E-class gas turbine, originating from ABB, later transferred to Alstom, and ultimately acquired by GE. First introduced in 1993, it has undergone continuous upgrades and improvements, including the GT13E2 2005 and GT13E2 2012 models. The early version had a power of approximately 179.9 MW and an efficiency of 36.9%. After an upgrade in 2012, the power exceeded 200 MW, with an efficiency increase to 38%, and a combined cycle efficiency of 55.2%. It features a 21-stage subsonic compressor with a pressure ratio of 16.9 and variable guide vanes, ensuring high start-up reliability. The annular combustion chamber utilizes environmentally friendly burners, with 72 standard burners and no transition sections or cross-fire tubes. The turbine is a five-stage design, ensuring long component life. The integrally welded rotor features forged disks, and the turbine blades utilize axial fir-tree roots, ensuring lifetime maintenance-free operation.

This 72-hour trial run is a key milestone in the unit's transition from construction to commercial operation. Upon completion, the project will effectively alleviate Nigeria's current power shortage, provide stable energy support for local industrial development and improvements in livelihoods, further deepen China-Nigeria energy cooperation, and demonstrate the overseas service capabilities of Chinese power companies. Yufeng Power will continue to collaborate with all parties to monitor data during the trial run to ensure the successful completion of testing tasks and lay a solid foundation for the official handover of the project.
