Chlorocarbon-lnduced Incomplete Combustion In A Jet-Stirred Reactor

Abstract

Abstract The chemistry leading to products of incomplete combustion, as affected by chlorocarbons, was studied by modeling data from a jet-stirred reactor, verifield experimentally to be at nearly perfectly-stirred conditions. Premixed, fuel-rich mixtures of C2H4, CH3Cl, and air were burned in a toroidal jet-stirred combustor. Instantaneous measurements of local temperature were obtained using laser Rayleigh scattering. and extractive probe sampling followed by gas chromatography was used to determine concentrations of stable species. Reactor temperature, and equivalence ratio (φ) were held constant, while the chlorine content was varied by modifying the C2H4, CH3Cl, and diluent N2 flows. The instantaneous temperature measurements showed that the reactor remains nearly perfectly-stirred, even to the point of blowout. A perfectly stirred reactor (PSR) model indicated that the principal effect of chlorine addition was that of inhibiting the burnout of CO to CO2, consistent with the experimental observation ...
