Abstract

The overall chemical rate and chemical effect of CF 3 Br, 2-BTP and 2-BTP/CO 2 with hydrocarbon flames are calculated using the perfectly stirred reactor (PSR) model. The chemical effects of CF 3 Br with CH 4 /air flames always inhibit combustion. The chemical saturation concentration of CF 3 Br in stoichiometric and lean ( Φ = 0.6) CH 4 /air flames at 298 K and 1 bar is roughly 2.5% and 0.8%, respectively. The overall chemical rate of 2-BTP with moist C 3 H 8 /air flames is always less than the uninhibited condition and fluctuates with sub-inerting agent additions. The net chemical effect variation of 2-BTP is more complicated than experimented and calculated flame speeds with 2-BTP added to lean hydrocarbon flames. There are negative chemical effects (chemical combustion effects) with certain sub-inerting 2-BTP concentrations (0.015 ≤ Xa ≤ 0.034), which result in the experimented unwanted combustion enhancement in lean moist C 3 H 8 /air flames. CO 2 can obviously improve the inhibition effect of 2-BTP in lean moist C 3 H 8 /air flames, driving negative chemical effects (enhance combustion) into positive chemical effects (inhibit combustion) with lean moist C 3 H 8 /air flames. No enhanced combustion would occur with the blends (2-BTP/CO 2 ) when CO 2 addition is larger than 4% in Φ = 0.6 moist C 3 H 8 /air flames at 298 K and 1 bar.
