; Ca-based absorbent injection into the furnace is a low cost desulphurization technology. This paper describes the research on chemical and physical reaction mechanism and model in-furnace by using of Ca-based absorbent for capture SO2, experiments of desulphurization have been carried out in a 0.15 million kcal/h thermal capacity one-dimensional coal combustion test facility, 56% to 74% sulfur removal rate can be achieved while Ca/S was about 2 . A simple one-dimensional mathematics model have been developed, the error within 10% can be get between theory and experimental results.
