Core Business

To solidify its position in the steel industry, India's BHUSHAN Steel Company is actively promoting industrial upgrading and is fully committed to building an 800,000-ton/year hot-recovery coke oven project. This project occupies a key position in the company's strategic layout and is of great significance to the development of India's steel industry.

Shanxi Qinze Coking Co., Ltd., in order to adapt to the development trend of the coking industry and enhance its competitiveness, is vigorously promoting a 400,000-ton/year heat recovery coke oven project. This project occupies a core position in the company's development strategy and has a positive promoting effect on the upgrading of Shanxi's coking industry.

The 8xl0-hole heat recovery coke oven project of Shanxi Gaoping Xinggao Coking Co., Ltd., constructed by our company, has won the honorary title of "Model Enterprise for Energy Conservation and Greenhouse Gas Emission Reduction in Chinese Towns and Villages" awarded by the United Nations Environment Programme, the United Nations Industrial Development Organization, and the Global Environment Fund Ministry of Agriculture of the People's Republic of China, due to its excellent construction quality, environmental protection, energy efficiency, and compliance with gas emission standards. It has also become a model project for learning and training by large coking plants both domestically and internationally.

The 800,000-ton/year heat recovery coke oven of Vietnam and Fa Group demonstrates remarkable industrial strength. Designed by China ENFI Engineering Technology Co., Ltd., this advanced coke oven boasts an annual production capacity of 800,000 tons, efficiently meeting large-scale production demands. 

The 800,000-ton/year heat recovery coke oven and associated waste heat boiler and desulfurization and dust removal equipment of Vietnam and Fa Group are technologically advanced and functionally excellent. As a key part of the waste heat recovery system, the waste heat boiler efficiently gathers waste heat from coking. Its unique structural design makes heat absorption and transfer more efficient, achieving full utilization of energy. The high-temperature steam generated can be used for power generation or industrial production, reducing energy consumption costs.

The waste gas circulation system, meticulously crafted by Vietnam and Fa Group for their 800,000-ton/year heat recovery coke oven, is core equipment for achieving efficient and clean production. Through ingenious process design, the system reintroduces some of the waste gas generated by coke oven combustion back into the combustion area for circulation. In this process, the waste gas plays a role in diluting the combustion air and balancing the temperature distribution inside the furnace, significantly improving combustion efficiency.

This coke oven, with an annual output of 100,000 tons, is a high-efficiency and high-quality equipment for producing coke. It adopts advanced external heating vertical pulverized coal pyrolysis technology, using low-rank lignite as raw material, and through precise pyrolysis reaction, it stably produces high-quality coke. At the technical level, the furnace body structure is ingeniously designed, which can effectively control the reaction process, ensure the pyrolysis process is efficient and stable, and greatly improve the coke production efficiency.

The 65-hole 4.3m coke oven is a key piece of equipment for efficient coking in the metallurgical and chemical industries. Its body consists of carbonization chambers, combustion chambers, and regenerator chambers. 65 carbonization chambers are arranged alternately with combustion chambers, each combustion chamber containing 20-30 vertical flues; the structure is scientific and reasonable.

The installation of the 65-hole 4.3m coke oven steel structure is a complex and crucial project. At the beginning of the installation, a professional team carefully checked and pre-assembled various steel structural components according to precise design drawings to ensure that all components fit correctly. During the installation process, advanced lifting equipment was used to accurately lift and place furnace columns, steel beams, and other components weighing several tons to their designated positions.

The 1.2 million-ton-per-year 5.5M coke oven chemical production system is a key facility for the efficient production of coke and various chemical products. Its annual production capacity reaches 1.2 million tons, demonstrating a significant scale advantage. This system uses advanced technology to conduct in-depth processing of the crude coal gas generated during the coking process. Through a series of processes such as condensation, absorption, and distillation, various high-value-added chemical products such as crude benzene, tar, and ammonium sulfate can be separated.

A 1 million-ton-per-year 6.25M coke oven chemical production system, a paragon of excellence in the coking industry. Its impressive annual capacity of 1 million tons provides a solid foundation for large-scale production. Relying on advanced technology, this system performs comprehensive and in-depth processing of the crude coal gas generated during coking. Through condensation, high-temperature tar and water vapor are separated from the gas; using absorption and distillation techniques, valuable chemical products such as crude benzene and ammonium sulfate are successfully refined.

Coke oven chambers are the core of the coking process. Taking a typical coke oven as an example, its interior is a narrow rectangular structure, carefully built with high-quality silicon bricks, capable of withstanding temperatures exceeding 1000℃. During coking, coal is precisely fed into the carbonization chamber, where it is heated and decomposed in the absence of air. As the temperature gradually increases, the coal undergoes several stages: drying, pyrolysis, semi-coke formation, and coke maturation.
