According to Lu’an Group, the world’s largest gas-membrane intelligent coal storage facility in the power industry has been successfully constructed at Lu’an Ronghai Power Generation Co., Ltd. The gas membrane coal shed is 145 meters long, 128 meters wide, and 54 meters high, covering an area of 19,000 square meters; it can store 200,000 tons of coal when fully filled. As this gas-film coal shed is completely airtight, it fundamentally solves the environmental protection issues faced by power generation companies, contributing to the reduction of pollution and haze in the Changzhi area. Zhang Xi, deputy general manager of Ronghai Power Generation, said that the gas-membrane intelligent coal shed has been operating normally during its four months of trial operation. This project has the following advantages: First, it can be built quickly, and construction is possible in winter. II. It has good airtightness, reducing dust pollution. III. Low cost: 50% lower than the original steel structure budget. IV. Low operating costs; fully automated and unattended, with only electricity costs required. It fully meets various requirements such as corporate costs and environmental protection. An air membrane coal shed consists of a civil engineering section and a membrane section (membrane system, cable system, lighting system, access control system, foundation anchoring and connection system, fresh air regulation system, intelligent monitoring, alarm, and control system for the air membrane itself, backup power supply system, remote communication and control system, fire protection system, and internal environment monitoring and management system). It features safety, stability, scientific design, environmental friendliness, intelligence, and a high degree of automation. There are other outstanding advantages of this building that are unmatched: 1. Simple structure and fast construction speed. It can also be completely disassembled, relocated, and reused. 2. Low cost, with inexpensive construction expenses. It is more than 50% lower than steel structure buildings, and the advantage becomes more significant as the building span increases. 3. High safety, lightweight materials, with no safety hazards. It has excellent airtightness, offering clear advantages in terms of energy conservation and environmental protection. 4. Extra-large space, without beams or columns, with a high volume ratio; large mechanical equipment can be installed there for use. In special circumstances, a temporary excess inventory of over 50% can be achieved. 5. Resistant to acids and alkalis, with strong corrosion resistance and aging resistance. 6. Advanced technology and high level of intelligence. By installing sensors for gas, carbon monoxide, dust, internal pressure, wind force, etc., as well as automatic control devices, it can operate unattended. 7. The building’s exterior is simple and stylish, possessing a contemporary aesthetic that helps enhance the company’s image. 8. The building shape can be freely designed, coloring can be arbitrary, and it can be used as an advertising medium. The project contractor, Aide Mei (Beijing) Gas Membrane Technology Co., Ltd., is one of the pioneers in the field of gas membrane building technology in China. It possesses multiple patented technologies. During the construction of this project, difficulties such as large engineering spans, severe winter conditions, and the need to carry out construction without stopping work were overcome. Through close cooperation with relevant units of Lu’an Group, numerous technical improvements were made to enhance the suitability of the existing gas membrane coal shed, enabling the successful completion of the project. The air film building of Lu’an Ronghai Power Generation Company will serve as a model for environmentally friendly enclosed coverage of coal storage areas in Shanxi, contributing to the development of the Lu’an Group into a world-class modern coal chemical enterprise.
