Biruk Chiu Choi John Kang Journal on Power Systems Engineering 2322–0376 5 2 1 9 Integrated Recycle Heat Exchanger, Circulating Fluidized Bed Boiler, Regression Modeling, Neural Network Modelling This paper describes the mathematical modelling of an Integrated Recycle Heat Exchanger in a 300 MW Circulating Fluidized Bed Boiler currently in operation in the Northside Power Generation Plant of JEA. Numerical data were collected from the operation. The data were used in the development and training of regression and neural network models for the Integrated Recycle Heat Exchanger. The performance of the regression and neural network models were compared using five different criteria. The findings were described in this paper. Minor differences between the performances of these models were also discussed. May - July 2017 Copyright © 2017 i-manager publications.
