摘要

This paper presents a study on the combustion behavior and flight characteristics of non-spherical black liquor particles by means of detailed numerical simulations, giving useful information for developing up-to-date simplified single particle combustion models for CFD. The role of particle shape when the experimental single particle combustion data is used for model validation is also discussed. The results from this paper suggest that the particle shape has a significant effect on the combustion and flight behavior of single black liquor particles. Therefore, combustion models for black liquor particles should be updated and the non-spherical shape considered in furnace simulations for cases wherein a significant fraction of non-spherical particles is observed.
