In July 2018, Beijing Energy Future City Gas Thermal Power Co., Ltd. and Shanghai Electric signed a service contract for gas turbine HGPI and upgrade. Shanghai Electric provides upgraded turbine blades and spare parts, as well as inspection supervision services. In November 2019, the gas turbine HGPI was successfully completed, and the efficiency and output of the unit were significantly improved.
This HGPI is the first domestic E-grade gas turbine unit to have independent flow modification and axial thrust self-balancing design transformation. After the HGPI, the output of the gas turbine unit will increase by about 13.5MW, the efficiency will increase by about 1.1%, and the maintenance interval will be extended by 8000EOH. This HGPI adopted the unit's entire process design technology, including overall thermal scheme matching, secondary air system optimization, turbine blade life assessment, and compressor control parameter optimization. It achieved significant results and reached the international advanced level.
