Product Description
The underground flue of the clean coke oven at Mingyuan Coke in Qinshui, Shanxi, is a key passage for ensuring the normal operation of the coke oven. Its condition directly affects production efficiency, energy consumption, and environmental protection effects. Given that the underground flue has been subjected to high temperatures, corrosive gases, and a complex geological environment for a long time, resulting in varying degrees of damage, Mingyuan Coke actively carried out an underground flue repair project.
In terms of repair technology, the project team, with its rich experience and professional skills, adopted an innovative process. First, advanced testing equipment was used to accurately identify the location and extent of damage to the flue. Addressing the challenges of high temperatures and confined spaces inside the flue, specially-designed repair materials that are high-temperature resistant, corrosion-resistant, and highly flexible were selected, facilitating construction in complex environments. During repairs, a segmented repair method was used, with damaged sections cleaned, repaired, and reinforced one by one. In the repair process, professional welding and sealing techniques were used to ensure that the flue connections were tight and seamless, preventing gas leaks and heat loss.
This repair project is expected to achieve positive results in several areas. First, the flow performance of the underground flue will be significantly improved, ensuring smooth discharge of coke oven waste gas, improving coking efficiency, reducing production downtime, and improving the overall production efficiency of the enterprise. Second, the repaired flue can effectively reduce heat loss, improve energy utilization, and reduce energy consumption costs. Furthermore, the well-sealed flue can reduce the emission of harmful gases, reducing environmental pollution risks, helping the company strictly abide by environmental regulations, practicing the concept of green development, and promoting the high-quality and sustainable development of Mingyuan Coke.
