Progress of Guanghui’s 10 million tons per year coal grading, quality improvement, and comprehensive utilization project. Author/Source: Huahua Network – Coal Chemical Industry. Date: December 10, 2019. Clicks: 50. Recently, the large-scale drying equipment for the coal quality improvement project carried out by the Xinjiang Guanghui Coal Clean Processing Co., Ltd., and constructed by the Fourth Engineering Company of China National Chemical Engineering Group No. 11 Construction Co., Ltd.’s Xinjiang Guanghui project team, was successfully installed in place in one go. The 10 million tons per year coal grading, upgrading, and clean utilization project of Xinjiang Guanghui Coal Clean Processing Co., Ltd. began construction in 2013. The facility is equipped with 72 carbonization furnaces and is capable of processing 10 million tons of coal per year; it represents the largest coal grading, upgrading, and comprehensive utilization project currently in operation in China. According to the process design, the carbonization furnaces in Phase 1 of the 10 million tons per year coal grading, upgrading, and clean utilization project are divided into three series. Specifically, the second series of carbonization units was put into operation in June 2018, the first series in December 2018, and the third series in November 2019. All three production lines of the Clean Refining Company have met the conditions for capitalization and have been put into operation officially. This dryer unit has a diameter of 5.85 meters, a length of 11.4 meters, and a weight of around 230 tons; it is the heaviest single unit used in the construction and installation of the coal upgrading drying project carried out by Xinjiang Guanghui Coal Clean Processing Co., Ltd. Due to the limited construction space in the factory building and the location of the foundation, lifting is quite difficult. Before the lifting operation, the project team’s technical personnel studied the lifting plan on multiple occasions, developing detailed and feasible construction measures as well as specific procedures for the lifting process. Various departments worked closely together to conduct a thorough inspection of the lifting equipment and tools, and provided technical and safety instructions to the relevant personnel. At the site, three large cranes – a Sany 600-ton crane and a Liebherr 500-ton crane – were used, employing a dual-crane lifting method to lift the 3 dryers into place efficiently and with high quality, all at once.
