A gas monitoring system applying the infrared absorption method has been developed for continuous monitoring of gas generation during the coking process of coal. The developed system made it possible to continuously monitor coking reactions in a wide temperature range up to 1000°C and thus, to follow pyrolysis of the coal in real time. The system was fitted to a commercially operating coke oven to analyze the COG generated during a whole cycle of the coking operation, which yielded information on the details of coking reactions that took place at different stages of the coking cycle. The monitoring results also quantitatively clarified the difference in COG generation of different coal blends. Source
