Jun 30, 2020 Past experience shows that the fineness of the limestone flour (used for desulfurization) in power plants is generally required to be between 200 and 325 meshes. So it requires that the output size of grinding mill need to reach the standard. For the coal boiler which is low sulfur content in combustion, the fineness of the limestone flour ...
In the process of dry scrubbing injection systems, lime is used as a reagent to react and remove gaseous pollutants. There are two common dry methods, the dry injection system and spray drying systems. Each process injects lime into flue gas to remove SO2. A dry injection process injects dry hydrated lime directly into the flue gas duct, whereas the spray dry system injects
