Abstract
The chemical structure of one-dimensional, fuel-rich, laminar flat flames of 1,2-C2 H4Cl2/CH4/ O2/Ar were studied using a quartz micro-probe and on-line mass spectrometry. Mole fraction profiles determined using the same micro-probe with and without cooling water were considerably different, and indicated the continuation of reactions in the uncooled probe. These results suggest the need to evaluate the effects of probe cooling to acquire quantitative data on the structure of flames of chlorinated hydrocarbons.
