Dynamic Model Identification of the Super-Heated Steam Temperature for 300MW Circulating Fluidized Bed Boiler (CFBB)

The dynamic model of 300MW CFBB super-heated steam temperature is established which takes the desuperheating water mass as the input and the inlet and outlet super-heated steam temperature as the output. Recursive least square (RLS) is used to identify the model parameters and the ideal identification result is achieved. The result provides a reference for the analysis and control of the dynamic characteristics of the 300MW CFBB.
