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.

A ring furnace is a highly efficient industrial heating device. Its unique ring structure design consists of a furnace body, a combustion system, and an exhaust system. The furnace body is circular, and the material being heated moves in a ring channel, resulting in more even heating. The combustion system is equipped with multiple burners, evenly distributed around the furnace wall. The flame size and temperature can be flexibly adjusted according to process requirements, ensuring complete fuel combustion and a thermal efficiency of over 80%.

The walking beam furnace is an important piece of equipment in industrial heating. It mainly consists of a furnace body, a walking beam mechanism, a combustion system, and a temperature control system. The furnace body is constructed of high-quality refractory materials to effectively reduce heat loss. The walking beam mechanism acts like a material 'transport track', pushing materials to move orderly within the furnace through periodic lifting, advancing, lowering, and retreating actions to achieve continuous heating. The combustion system is equipped with high-efficiency burners, accurately controlling fuel supply and combustion intensity based on process requirements to ensure stable heat output.

The automotive wheel hub heat treatment furnace is core equipment that ensures the quality and performance of automotive wheel hubs. Its furnace body adopts a multi-layer composite insulation structure, with an inner layer of high-temperature alloy material and an outer layer of high-quality heat insulation material, effectively reducing heat loss and improving energy utilization. The furnace is equipped with a high-precision temperature control system that can control temperature fluctuations within a very small range, ensuring the temperature accuracy during the wheel hub heat treatment process and meeting the stringent requirements of different material wheel hubs for heat treatment temperature.
