Experimental determination of reaction kinetics for the release of chlorine and sulfur spe-cies and for the conversion of these species in the gas phase (A03)

在子项目A3中，扩展了描述富氧燃料燃烧中氯和硫化学的模型，以考虑氮和碱性物质。用这些模型可以预测含Cl、S、N的次要物种的形成以及碱与Cl、S物种的相互作用。相关的实验研究将在气流床反应器中进行，并通过热重分析。将改进第一个供资期采用质谱法对高活性氯和硫物质进行提取测量的技术，以便能够测量含氮的次要物质。

In subproject A3, models for the description of chlorine and sulfur chemistry in oxy-fuel combustion are extended to account for nitrogen and alkaline species. The formation of Cl, S and N bearing minor species as well as the interaction of alkali with Cl and S species can be predicted with these models. Related experimental investigations will be performed in an entrained flow reactor and by thermogravimetric analysis. The extractive measuring technique for highly reactive Cl and S species applying mass spectrometry utilized in the first funding period will be improved to enable the measurement of N-bearing minor species.
