The Research on Waste Heat Utilization Technology of Coke Oven Gas in Ascension Pipe.

This paper provided an overview of various coke oven gas (COG) heat utilization technologies in the coke oven ascension pipe. The prevailing technology currently used is the distributed sensible heat recovery method, specifically water-jacketed and coil-type waste heat utilization technologies. However, it still faces challenges such as coking and low heat exchange efficiency. Currently, no flawless technology exists. In the future, the focus will be on discovering appropriate materials, enhancing technological security, and optimizing waste heat utilization efficiency. Given the growing emphasis on energy conservation and emission reduction, the utilization of waste heat from ascension pipes through COG heat recovery technology holds significant potential.
