What kind of desulfurization limestone powder used in power plant?
The central column mill. He is a professional power plant desulfurization equipment, inside and outside the two concentric rotary body at different speeds to rotate in the opposite direction, the medium and low implementation of repeated rolling grinding on the material layer to the supercritical speed close to the cylinder wall. The central column mill after a through the grinding material is mostly powder,
Most CFB boilers basically use 0 to 1mm particle size range of limestone, and as much as possible to reduce the share of fine powder
Now the most used power plant circulating fluidized bed boiler, circulating fluidized bed boiler desulfurization using limestone, limestone particle diameter should be less than 1mm, from the size distribution, most of the particles diameter should be concentrated in the nearby region of D50.
