Modeling and Simulation of 1025t/h CFBB Combustion Chamber

This paper takes CFBB as simulating object, which has characters of DG1025/17.4-II1 two legs furnace and with external heat exchanger. Combined with thermal process and combustion chamber working characteristics of practical unit, a general dynamic model arithmetic library of CFBB combustion chamber was set up based on a kind of graphic modeling real time simulating support system. In the arithmetic library, the dynamic and static characteristics of combustion chamber was taken into consideration, including the flowing, burning, heat exchanging process and mechanism in combustion chamber. Using the library, a 1025 t/h CFBB combustion chamber simulating model was developed. It is shown by simulation results that the model can correctly reflect the dynamic characteristic of CFBB combustion chamber.
