Spray-Drying
Desulfurization Process
Currently, there are 75% of refuse incineration projects
in the world adopting this
technique.
The typical and mature semidry process
desulfurization is widely adopted in small power plant,
heating plant and craftwork kiln, particularly
in the refuse incineration plant. There are 75%
of refuse incineration projects are using it.
Theory
The dripping from fixed sprayer reacts with the gas
from top of the tower and vaporizes before it drops
to the bottom. The reactant is in a dry status and will
be separated in the filer-bag dust collector (or ESP). At the same time, SOx,
HF and HCL will also be removed too.
