Combustion of CWM Droplets. 2nd Report, Estimation of Mass Changes of Flying Droplets.

Abstract

Combustion of flying CWM droplets in an electric furnace was investigated to obtain basic data on the mass changes of CWM spray. The calculation model for the mass reduction of a single CWM droplet was made based on the experimental results on mass changes and combustion periods in the combustion of a suspended droplet. Using this model with the residence times of droplets calculated from flying velocities, mass changes of droplets for their flying distance were calculated. With these mass changes and size distribution of flying droplets in the furnace, their total mass changes were calculated and compared with the experimental data. The calculated values approximately agree with the experimental values except the furnace inlet where calculated mass reductions are less than experimental data.
