Let’s give a thumbs up and encouragement to the achievements made in China’s chemical engineering technology and equipment. Your participation in the discussion serves as the greatest motivation! ********************** [Ten Years of Great Development in Chemical Engineering Equipment] This is a continuously updated compilation post; all are welcome to join the discussion: https://bbs.hcbbs.com/thread-3576046-1-1.html ***************** Lujiayu Gas Power Plant has made significant breakthroughs in power generation using low-concentration gas. Jinju Coal, Electricity, and Chemical Co., Ltd., a subsidiary of Jineng Holding Equipment Manufacturing Group, has actively carried out systematic innovation efforts at its Lujiayu Gas Power Plant, successfully overcoming the technical challenges related to power generation from low-concentration gas. As the first demonstration project in China to utilize domestic low-concentration gas generator sets for large-scale use of gas resources, this project has achieved significant results in terms of safe production and energy conservation and emission reduction. It has also seen substantial progress in improving economic efficiency, thus fully playing the role of a benchmark project for the industry. Technological innovation to build core competitiveness: In light of the imperfect technical framework and limited practical experience in low-concentration gas power generation in China, the research team behind this power plant focused on the technical bottlenecks and made concerted efforts to address them. By conducting in-depth studies on the physicochemical properties of low-concentration gas, they adopted innovative high-efficiency preprocessing techniques to effectively remove impurities and moisture from the gas source, thereby increasing the purity and calorific value of the gas and ensuring a high-quality gas supply for the stable operation of the generators. In terms of equipment application, after introducing domestic low-concentration gas generator sets, the power plant focused on optimizing and upgrading key components such as the combustion system and control system. Through multiple rounds of testing, debugging, and parameter optimization, the power generation efficiency, operational stability, and equipment durability of the unit have been significantly improved, resulting in a technical system with independent intellectual property rights. Empowered by intelligence, management is upgraded. During the construction of the plant’s second phase, an intelligent power plant management platform was introduced, integrating Internet of Things sensing, artificial intelligence algorithms, and 3D modeling technologies to create an intelligent management system that covers the entire process, including personnel management, material flow, equipment operation, and environmental monitoring. The high-definition smart display in the control center allows for real-time updates of production data from the factory site. Managers can use this visual interface to carry out precise scheduling, monitor key parameters in real time, and analyze trends, thereby preventing safety risks in advance. The power plant also utilizes 3D visualization modeling and big data diagnosis technologies to establish effective mechanisms for predicting equipment failures, assessing dynamic lifespan, and carrying out condition-based maintenance, thereby improving safety levels in operations and providing a solid guarantee for the continuous and stable operation of the units. With its multi-dimensional value and prominent demonstration effect, in terms of energy conservation and emission reduction, this power plant consumes 45.07 million Nm³ of methane-equivalent per year, and generates 182.6 million kWh of electricity annually. This translates to a reduction of 676,100 tons of carbon dioxide emissions, making it a significant contributor to cutting greenhouse gas emissions, improving the regional air quality, and helping to achieve the \"dual carbon\" goals. In terms of economic benefits, this power plant expands its revenue streams through technologies such as waste heat recovery, thereby achieving efficient comprehensive utilization of resources and maximizing the economic benefits of the enterprise.
