A continuous monitoring system for gas generation in coke oven has been established with the Fourier-transform infrared spectroscopic analyzer (FT-IR) as a detector. Coke oven gas (COG) was sampled in an ascension pipe by a pump. COG, passed through traps for removing tar and mist, was led to the detector located about 20 m from the sampling position. COG was monitored with 50 times dilution by nitrogen gas because the concentrations of component gases are too high for the FT-IR measurement. Using this system, the COG of a coke oven was measured continuously for about 20 h. By monitoring the generation behavior of COG, it was possible to characterize the details of the coking reaction in a coke oven. It was shown that different combinations of coals result in different COG generation behavior.
