Construction of reinforced concrete columns for the large-scale upgrading project of Henan Tianrui Coal Chemical Industry’s green, intelligent, low-carbon and environmentally friendly equipment

Thread Content

The large-scale upgrading project for green, intelligent, low-carbon and environmentally friendly equipment in Henan Tianrui Coal Chemical Industry is a key project in Henan Province, with an investment of 8.5 billion yuan in the first phase. The large-scale intelligent coking technology, which won the First Prize for Scientific and Technological Progress from MCC Coking & Refractory, is employed; the main components of this system consist of 4x70-chamber coke ovens with a height of 7.65m and a top-loading, single-heating design. Supporting facilities include a coal preparation system, 3x260t/h dry quenching systems, a coke treatment system, a gas purification system, as well as various auxiliary systems. This project is designed and constructed with informatization, networking, digitalization, intelligence, automation, sustainability, and efficiency as its key improvement areas. Once completed and put into operation, it will produce 3.6 million tons of dry coke per year, 200,000 tons of tar, 48,000 tons of crude benzene, 41,000 tons of ammonium sulfate, and 490 million kWh of electricity. It will also create more than 380 new job opportunities, with an annual output value of over 11 billion yuan. It is reported that the main line of the 7.65m coke ovens in the Tianrui Coal Chemical Industry upgrading project has an annual production capacity of 3.65 million tons. The construction of coke ovens No. 3 and No. 4, as well as the second coal tower, was carried out by the Metallurgical Branch under the 22nd Metallurgical Construction Corporation. The construction of the foundations for coke ovens No. 3 and No. 4 has been completed; a total of 15,000 cubic meters of concrete have been poured. At present, work is underway on constructing the reinforced concrete columns, with completion planned by the end of March. Subsequently, the critical task of constructing the roof structures for the coke ovens will be undertaken. The central road among the three main roads has been fully completed. Since work began on January 6th, over two months ago, Tianrui Group and China 22nd Metallurgical Group have worked together in good cooperation, with progress proceeding smoothly. Construction on the project has never stopped, and it is advancing steadily toward the established goals. On March 6, a contract was signed with the Zhejiang branch of the 22nd Metallurgical Construction Company, covering the civil engineering work for coal processing facilities and coke processing facilities; the project duration is 365 days, with construction to begin 15 days later. Our target deadline is to complete the commissioning of Furnace No. 3 by the end of 2025, with Furnace No. 4’s commissioning postponed by one month.
