石灰石（CaCO 3）是一种常用的钙基脱硫剂，其多孔分解产物（CaO）的比表面积对燃烧系统中SO2/H2 S的脱除有很大影响.根据反应动力学、不同反应温度下石灰石的分解特性和多孔氧化钙的比表面积，分析了烧结气氛和颗粒尺寸，考虑了CO2在多孔产物层中的扩散对分解的影响，分解过程中CaO的烧结以及CO2对烧结的影响。
Limestone (CaCO 3) is a commonly-used calcium-based sorbent.The specific surface area of the porous decomposition product (CaO) has a great effect on the removal of SO 2/H 2S in combustion systems.Based on the reaction kinetics,the decomposition properties of limestone and the specific surface area of porous calcium oxide at various reaction temperatures,atmospheres and particle sizes are analyzed in this paper.The influences of CO 2 diffusion in porous product layer on decomposition,sintering of CaO during decomposition process and CO 2 on sintering were considered.
