The surplus pressure power generation project of Zhengyuan Hydrogen Energy passed the pre-acceptance inspection for trial production. Author/Source: Lu’an Zhengyuan Group. Date: February 20, 2022. Clicks: 21. On January 26, the Safety Supervision Bureau of Cangzhou City organized an expert team to conduct a pre-acceptance review of the surplus pressure power generation project using recycled water at Zhengyuan Hydrogen Energy. Representatives from design firms, construction companies, and technology providers attended the meeting. Together, they conducted a thorough review of the design drawings, construction documents, and trial production plans for the project aimed at generating electricity using the residual pressure of circulating water. They also inspected the actual quality of construction work on site. The expert group asked detailed questions about potential issues that might arise during the trial production phase, and the attendees provided detailed answers. In the end, the project passed the pre-acceptance check for trial production successfully. The circulating water residual pressure power generation project is a new energy-saving initiative. It involves installing a turbine generator on each of the 7 return pipelines for the comprehensive circulating water system, in order to recover the residual pressure energy from the circulating water. The recovered energy is converted into electrical power and fed into the company’s internal power grid for use by other equipment; the annual power generation capacity is 6.7144 million kWh. Based on the information gathered and the on-site inspections, the expert group believes that the excess pressure power generation project was constructed and built in strict accordance with the requirements for safety facility design; the surrounding environment meets safety standards, electrical and monitoring/alarm devices are available in sufficient quantity, and all necessary safety protection devices are present. The control measures such as monitoring and alarm systems implemented during the production process comply with relevant regulations, allowing the project to pass the acceptance inspection for safety facilities. The group also provided further suggestions for improvement.
