a b s t r a c tThe influence of HCl on CO and NO emissions was experimentally investigated in an entrained flow reactor (EFR) and an internally circulating fluidized bed (ICFB). The results in EFR show the addition of HCl inhibits CO oxidation and NO formation at 1073 K and 1123 K. At the lower temperature (1073 K) the inhibition of HCl becomes more obvious. In ICFB, chlorine-containing plastic (PVC) was added to increase the concentration of HCl during the combustion of coal or coke. Results show that HCl is likely to enhance the reduction of NO and N 2 O. HCl greatly increases CO and CH 4 emission in the flue gas. A detailed mechanism of CO/NO/HCl/SO 2 system was used to model the effect of HCl in combustion. The results indicate that HCl not only promotes the recombination of radicals O, H, and OH, but also accelerates the chemical equilibration of radicals. The influence of HCl on the radicals mainly occurs at 800-1200 K.

“…All reviewers except for Kéromnès et al [47] used the same set of Arrhenius parameters. We accepted the Arrhenius equation that was first suggested by Mueller et al [64] as the mean rate expression. A constant uncertainty parameter fprior=0.7 defines a band that includes all review and experimental data.…”

Re-evaluation of the temperature-dependent uncertainty parameter f(T) of elementary reactions isproposed by considering all available direct measurements and theoretical calculations. A procedure is presented for making f(T) consistent with the form of the recommended Arrhenius expression. The corresponding uncertainty domain of the transformed Arrhenius parameters (ln A, n, E/R) is convex and centrally symmetric around the mean parameter set. The f(T) function can be stored efficiently using the covariance matrix of the transformed Arrhenius parameters.The calculation of the uncertainty of a backward rate coefficient from the uncertainty of the forward rate coefficient and thermodynamic data is discussed. For many rate coefficients, a large number of experimental and theoretical determinations are available, and a normal distribution can be assumed for the uncertainty of ln k. If little information is available for the rate coefficient, equal probability of the transformed Arrhenius parameters within their domain of uncertainty (i.e. uniform distribution) can be assumed. Algorithms are provided for sampling the transformed Arrhenius parameters with either normal or uniform distributions. A suite of computer codes is presented that allows the straightforward application of these methods. For 22 important elementary reactions of the H2 and syngas (wet CO) combustion systems, the Arrhenius parameters and 3 rd body collision efficiencies were collected from experimental, theoretical and review publications. For each elementary reaction, kmin and kmax limits were determined at several temperatures within a defined range of temperature. These rate coefficient limits were used to obtain a consistent uncertainty function f(T) and to calculate the covariance matrix of the transformed Arrhenius parameters.2

The rate constant for the CO+H2O2 reaction

The reaction CO+H 2 O 2 → HOCO+OH (R1) has been proposed as an important oxidation step for CO in CO/H 2 mixtures at low temperatures. In this paper the rate constant for the reaction at 713 K is determined based on the batch reactor experiments of Baldwin, Walker and Webster [Combust. . The results show that the reaction is significantly slower than indicated by an earlier rough estimate and it is probably of minor importance in combustion. The present analysis reconciles the batch reactor data of Baldwin et al. with recent highlevel theoretical work on the CO+HO 2 reaction.
