The Non-Iterative Estimation of Bed-to-Wall Heat Transfer Coefficient in a CFBC by Fuzzy Logic Methods

The Fuzzy Logic (FL) approach is proposed in this paper to determine the overall heat transfer coefficient in the combustion chamber of a large-scale 670 t/h circulating fluidized bed (CFB) boiler. The FL model for the prediction of bed-to-wall heat transfer coefficient was successfully validated against data from the boiler. The model can be easily applied by scientists and engineers for simulations and optimizations of CFB units.
