摘要

进行了描述在含金属混合物的过滤燃烧条件下形成的产物的组成的热力学计算。利用TERRA高温热化学平衡计算程序对产物的平衡组成进行了分析。根据计算结果,这些金属被分为两组。第一种形成冷凝相和气相,第二种形成仅处于冷凝相中的金属。在气相中存在金属化合物的情况下,通常是以下化合物:金属、氧化物、氢氧化物、氢化物、硫化物和金属硫酸盐。第二组金属不能在过滤燃烧波的条件下进行传质,并且将保留在固体燃烧产物中(在灰烬中)。

Thermodynamically Equilibrium Compositions of the Products Formed During the Filtration Combustion of the Metal-Containing Mixtures
Thermodynamic calculations for describing the compositions of the products formed in conditions of the filtration combustion of the metal-containing mixtures were carried out. The analysis of the equilibrium compositions of the products was carried out using the TERRA high-temperature thermochemical equilibrium calculation program. According to the results of calculations, the metals were divided into two groups. First one forms both the condensed and gaseous phases and in the second one ‒ metals that are only in the condensed phase. In case of the presence of metal compounds in the gas phase, as a rule, these are the following compounds: metals, oxides, hydroxides, hydrides, sulfides and metal sulfates. Metals of the second group cannot be subjected to mass transfer under conditions of the filtration combustion wave and will remain in solid combustion products (in ash).
