Abstract

A computer simulation method for liquid fuel spray combustion in a 1.2 m-I. D. × 5.0 m-long practical furnace was developed in this study. We used the k-ε two-equation turbulence model for predicting gas fields in the combustion furnace, on which were superimposed computations of the particle flights and the particle/gas interactions. Nitrogen oxide was computed by the modified Zeldovich mechanism for thermal NOx and by the Fenimore mechanism for fuel NOx. The combustion rate in the gas phase was determined by using the eddy dissipation model. The radiative heat transfer rate was calculated with a flux model between the wall and the gas field. The prediction of gas temperature and compositions in heavy oil combustion agreed well with experimental results.
