【Haichuan Chemical Salary News】Construction of Asia’s longest aerial coal transport corridor by Jinneng Group’s Huayu Coal Chemical completed
Thread Content
Jinmei Group owns the Huayu \"Circular Economy Industrial Park for the Clean Utilization of High-Sulfur Coal,\" which is the largest coal-to-oil production facility in the Jincheng area. This facility consumes 2.2 million tons of high-sulfur coal per year, producing 1.2 million tons of methanol and 500,000 tons of clean fuels annually. Well No. 2 in Sihe is the main raw material supply base for Huayu Coal Chemical Company. The distance between the two locations is 10.2 kilometers, and more than 50 coal transport trucks make over 300 round trips between them every day, placing significant strain on the local transportation system. To minimize pollution as much as possible, Jinnan Coal Group continues to explore cleaner methods of transporting and utilizing coal. By using a fully enclosed aerial corridor, it connects Well No. 2 in Sihe with Huayu Coal Chemical Co., Ltd., which is located 8.4 kilometers away; coal is thus delivered continuously to the chemical plant, achieving a \"seamless connection\" between the coal mine and the chemical plant.
Driven by the concepts of an innovative ecosystem and green development, Jinnan Coal Group invested 246 million yuan to initiate the construction of the clean coal transportation project for the Huayu integration project in October 2018. The project was constructed by Hongsheng Jian’an Branch of Jinmei Group; it passes through 7 administrative villages in two towns, crossing highways, provincial roads, 6 rural roads, and 18 high-voltage lines ； 325 support points were precisely positioned to install a conveyor belt over 8,000 meters long at a height of up to 25 meters. “We use tubular belt conveyors, which prevent spillage and leakage, and also safeguard the materials from being damaged by wind and rain as well as from contamination by materials outside the tubes. Furthermore, a higher conveying inclination increases the load capacity, and it is also possible to make turns between vertical and horizontal planes; it offers many advantages such as high safety levels, high conveying efficiency, and cost savings. ”Wang Jie told reporters that once the pipeline system is put into operation, it will enable the rapid transport of over 1,000 tons of raw coal per hour, in a manner that prevents the coal from coming into contact with the ground or being exposed to the air. Based on a transportation volume of 2.4 million tons per year, transportation costs can be saved by 18 million yuan in one year. (Reporters Li Zhijun, Wang Tianxiao) Reposted from: Shanxi Daily
Is there such an operation too? It indeed **reduces environmental and traffic pressures and eliminates dust generation altogether. I’m not sure if there is a backup line; is it necessary to stop the operation for maintenance?**

There is no need to use backup lines; the conveying equipment is easy to maintain. Moreover, coal storage bins are usually available at both ends, allowing the equipment to be shut down for maintenance without affecting operations at those ends
Oh, there’s padding on both ends, but this conveyor belt is really long – amazing!
Report on the fire incident involving the coal conveyor belt at a thermal power plant in Hebei on July 13th National Energy Information Platform 2019-08-13 21:34:04 [Read by energy professionals; click the top right corner to ‘Follow’] At around 5 a.m. on July 13, 2019, a fire broke out on the coal conveyor belt system at a thermal power plant in Hebei. This incident caused damage to belts No. 2 and No. 3, but the normal coal feeding to the unit was not affected. After the incident, the company established an accident investigation team. Adhering to the principles of \"not letting go until the cause is identified\" and \"seeking truth from facts, respecting science, and focusing on practical results\", the team carried out on-site inspections, reviewed relevant documents, gathered evidence, and conducted analyses to determine the causes of the incident, draw lessons from it, and implement preventive measures. Implement assessments on the relevant responsible persons in accordance with the company’s relevant regulations. To thoroughly draw lessons, strengthen the implementation of preventive measures, and prevent similar incidents from occurring, the relevant situation is hereby reported. I. Basic Information (1) Introduction to the coal conveying system: The coal conveying system consists of 13 belts, all of which are flame-retardant belts, numbered from 1 to 13. (II) Status of the coal conveying belts involved in the accident: The belts that caught fire in this incident were Belt No. 2 and Belt No. 3. Belts 1 to 4 are dedicated single-track belts for coal unloading from trains; they were built in 2010 and put into operation simultaneously with the generating units. The fire hazard classification of the pier is Class C, and its fire resistance rating is Grade 2. The structure type of the jetty is as follows: half consists of a concrete shear wall beam-slab-column system, while the other half is supported by steel structures; color-coated steel plates and rock wool insulation composite panels are used for the wall and roof cladding. For the steel structure section, H-shaped steel is used for the steel columns and roof trusses; the bottom of the jetty consists of a channel-shaped plate, along with a steel structure and a concrete surface layer serving as the base floor ； The wall panels are made of colored steel plates, with a thickness of 120 mm and a combustion performance rating of Class A. The conveyor belt model is DTII; its width is 1.4 meters and its speed is 2.5 meters per second. The second conveyor belt is 76 meters long, while the third conveyor belt is 97 meters long.
