    Abstract

    In CFB combustion, fuel conversion is limited by mass and heat transfer and chemical reactions inside the particle. In CFD simulation, computation of the local instantaneous conversion rate of a single fuel particle should be fast. The objective of the present study is to convert a shrinking particle model for coal combustion into a correlation based description that can easily be implemented in a CFD code. The single particle model was used to produce net reaction rates averaged over particle volume in a wide range of fluidization, temperature and composition conditions. The data was used to train neural network models that are fast to compute and easy to implement in a CFD code.
