Buying lime sorbent in understanding the concept of lime, lime is used to reflect the physical nature of the content: the color of lime, crystal structure, organization, smell, porosity, bulk density, specific gravity, bulk density, melting point, boiling point, thermal conductivity , specific heat, light, resistance, hardness, expansion coefficient, refractive index, angle of repose and the like. Limestone particle size (fineness) on the FGD system performance: Currently desulfurization absorber with PSD represents more fineness lime sorbent, which uses a mesh sieve screening limestone powder, used to represent the mass percent undersize limestone fineness of the powder. PSD limestone is an important design and operational parameters of lime desulfurization agents manufacturers, limestone powder limestone powder PSD determines the specific surface area, affecting the utilization rate of the reaction pH and limestone towers, these variables can affect a large extent desulfurization efficiency.
