en.Wedoany.com Reported - On June 19, the Luohe Million-kilowatt Project of China Energy Engineering Group Construction Co., Ltd. organized a special training on unit performance indicators and commissioning cases. The project's chief commissioning engineer delivered a lecture focusing on key aspects of thermal power unit commissioning, typical case analysis, and control of unit performance indicators. Project leaders, along with professional management and technical personnel from the Engineering Department, Quality Department, Thermal Power, Electrical and Instrumentation divisions, participated in the training. After the training, the project team simultaneously reviewed key issues such as alkaline cleaning of turbine pipelines, remaining work on the water-steam system, and problems affecting commissioning, sorted out the allocation of team resources, and further clarified the key tasks for the next phase, laying a solid foundation for the orderly progress of unit commissioning work.
Currently, the Luohe Million-kilowatt Project has entered a critical phase of installation and commissioning. Commissioning work is not only a comprehensive test of the project's construction achievements but also a vital step in ensuring the safe, stable, and efficient operation of the unit. This training closely aligned with the project's actual conditions, covering topics such as confirmation of commissioning conditions, system handover, equipment acceptance, performance indicator control, and prevention of typical problems. Drawing on commissioning cases from multiple million-kilowatt units in recent years, it systematically analyzed typical issues including flange seal leakage, boiler pressure component leakage, EH oil system leakage, insufficient condensate pump output, pipeline weld defects, and foreign objects left inside equipment. The training delved into the root causes of these problems, summarized lessons learned, and further strengthened the awareness of quality control throughout the entire process.
The training emphasized that commissioning work must adhere to the principles of "conditions first, acceptance first," strictly implement the system handover confirmation procedures, and comprehensively ensure the completion of building conditions such as platforms, railings, and lighting, as well as the confirmation of medium conditions like pipeline flushing, oil system cleanliness, and water-steam quality, to guarantee that each system meets the safety requirements for commissioning. For key aspects during the commissioning phase, such as energized areas and high-risk operations, the work ticket system must be strictly enforced, with measures for safety isolation, risk identification, and full-process monitoring implemented. The principle of "commission only when ready" must be upheld, resolutely avoiding blind rush work and commissioning with defects, thereby effectively ensuring the safety, quality, and efficiency of commissioning.
During the training, specific requirements for the full-process quality control of installation were also proposed based on typical cases. Key aspects such as flange connections, bolt tightening, weld inspection, support and hanger rechecks, and concealed work acceptance were highlighted. It was required to further strengthen construction process reviews and quality acceptance, achieving early detection of problems and early elimination of risks, reducing defects during the commissioning phase from the source, and creating favorable conditions for the smooth startup of the unit.
In the next step, the Luohe Million-kilowatt Project will take this training as an opportunity to adhere to the coordinated advancement of installation and commissioning, continuously strengthen professional capability building and commissioning talent cultivation, and steadily improve the level of quality control throughout the project process. It will comprehensively prepare for system completion, defect elimination, and commissioning readiness, fully clearing the critical path for unit operation, and providing solid support for the project to achieve its annual commissioning goals with high quality and high standards.
