摘要:
为研究煤中钠对SO3生成的作用规律，基于Gibbs自由能最小原理，使用反应动力学计算方法研究了常规空气燃烧方式下煤中钠对SO3生成的影响，分析了含钠气相化合物的形成转化与SO3生成和消耗的关系。研究结果表明：常规燃烧方式下，当烟气中不含有NaCl时，沿整个烟气流程中SO3的气相生成量最多；当烟气中含有NaCl时，NaCl蒸气初始体积分数越高，沿整个烟气流程中SO3气相生成量越少；烟气处于高温段时，气相含钠物相的生成与转化对SO3体积分数基本没有影响；烟气处于低温段时，气相NaHSO4的形成消耗了SO3，使其体积分数减少至0；气相Na2SO4的形成对SO3体积分数没有影响，主要受亚硫酸盐前驱体气相生成的控制；烟气中的钠对H、O、OH自由基浓度分布基本不产生影响。因此，常规燃烧方式下钠对SO3生成有抑制作用。
