Abstract
Details of the design and construction of a two-channel air-fuel ratio (AFR) chromatograph for the on-line analysis of a single sample of wet combustion gases are given. A thermal conductivity detector (TCD) is used to detect CO 2 and N 2 components, which are separated on a single column system. Then the ratio of the concentration of CO 2 and N 2 is used to determine the AFR in the original sample. The column used is a stainless-steel tube ( 3 in. × 1 8 in. I.D. ) filled with 80 mesh Porapak Q. A switching valve is incorporated to divert the samples between the separating column. The instrument is fully automatic and capable of determining two different AFR measurements in a working time of less than 5 s. It can operate satisfactorily at mixture strengths that are well above stoichiometric levels.
