Implementation of the Finite Volume Method for Calculating Radiative Transfer in a Pulverized Fuel Flame

Abstract

The newly developed Finite Volume Method (FVM) was incorporated into a general pulverized fuel (PF) flame model to predict radiative heat transfer in furnaces. The code was applied to a benchmark test case where exact radiative heat transfer solutions were available and to a pilot scale front-firing tunnel furnace where flame measurements had been taken. The FVM predictions were found to approach the exact solutions in the benchmark case and compare well to the measured data in the pilot scale furnace. The results demonstrate the feasibility and potential of the FVM for radiation modelling in PF flames.
