摘要
Abstract
The present study investigated the vaporization kinetics of MgCl
2
CaCl
2
and their binary melts in a fluidized bed at 1073-1273 K
and developed a vaporization model for the binary melts to explore the possibility of achieving enhanced vaporization rate for the feedstock containing CaO greater than 0.2 wt%. The vaporization rate constant of MgCl
2
is more than seven times than that of CaCl
2
at 1273 K. The vaporization rate of the binary melt was significantly affected by the composition
a small quantity of CaCl
2
can remarkably deteriorate the overall vaporization rate. Experimental results coincide well with the numerical simulation by the vaporization model which regards the evolution of vaporization rate with melts composition. A correlation between the necessary operation temperature and the CaO/(CaO+MgO) of the feedstock was proposed. Predictions reveal that a similar vaporization rate for 0.2 wt%-0.4 wt% CaO content feedstock with 0.2 wt% could be achieved at lower than 1365 K.
