【Abstract】 The simulation of a limestone desulfurization system is conducted along with a desulfurization experiment of limestone heat decomposition products under various operating conditions. As a result, set up and selected is an optimum desulfurization dynamics model. Due to a complicated process of the desulfurization reaction there exist a relatively great variety of such dynamics models, which are difficult to be differentiated. In the present paper a sequential order experimental design method has been introduced to acquire a maximum quantity of experimental information and arrange on this basis the experimental points. By performing a screening selection according to a standard of maximum posterior probability an optimum dynamics model was acquired. Such a model can provide an important scientific basis for the study of the limestone desulfurization mechanism and the desulfurization techniques based on a calcium injection in a boiler.更多还原
