On 8 July, the upper and lower casings of the steam turbine at the POWERCHINA Toksun County (Wusitong) 100 MW CSP + 900 MW PV integrated project in Turpan City were precisely mated, marking the successful completion of the turbine casing closure.
As the core power-generation equipment in a CSP plant, the steam-turbine casing closure is the most technically demanding and quality-critical step in unit installation. To ensure the closure met the highest standards, the EPC consortium led by ZHONGNAN ENGINEERING CORPORATION LIMITED meticulously organized and scientifically planned every stage, systematically performing self-inspections item-by-item in strict accordance with “Quality Inspection Guidelines for Solar-Thermal Construction Works, Part 6: Pre-Casing-Closure Inspection.” The work was completed with extremely low tolerances and zero defects.
