【Abstract】 Aiming at the modeling problems of circulating fluidized bed (CFB) boiler, a new overall modeling procedure is designed and a CFB auto-modeling system based on symbolic calculation is constructed. Comparing with foreign product, this system is more efficient and flexible in the deductive procedure. Practical application showed that a CFB general mathematical model with auto-modeling system could save large sum of the model developing time, and make the researcher free from hard manual deduction and programming work. The method used in this general model and auto-modeling system could be extended to and act as a basis of the modeling work of a series of thermal power system, such as SFBC, PFBC and Gasifier.更多还原
