The ABC mathematical model of fume formation is based on aerosol dynam
ics. The model takes into account the mechanisms of gas-phase chemical
reactions, homogeneous and heterogeneous condensation, agglomeration,
and deposition. Researchers can user the model to estimate the size d
istributions and deposition rates of fume particles and vapors in a kr
aft recovery boiler. Model results are compared with fume measurements
made in an operating recovery boiler in a mill.
