A comprehensive thermochemical analysis of the equilibrium gaseous pro
duct composition resulting from burning chromium, hydrocarbon, and chl
orohydrocarbon polymers in air at 101 kPa is presented. Calculations h
ave been made over the range phi = 0.25-2.50 at adiabatic flame temper
atures from 600 to 2100 K. The main chromium-containing species formed
are CrO3, CrO2, CrO2Cl, and CrO2(OH). The yield of Cr(6 +) derivative
s reaches a maximum of 77% at 1650 K and phi = 0.25, mainly in the for
m of CrO3(g). The yield of CrO, CrOCl, CrOCl2, CrO2Cl2, CrOOH, and CrO
2(OH), does not exceed 0.1% of the initial chromium content, and that
of other chromium-containing species is less than 10(-2) mol%. A react
ion scheme is constructed on the basis of the data obtained. It includ
es reactions of the secondary oxidants CO2, H2O, HCl, OH, and O, as we
ll as the reducing agents CO, H-2, and H. (C) 1998 by The Combustion I
