Desulfurization process and equipment are effective measures to solve sulfur dioxide pollution discharge in large fire power plants. Limestone gypsum wet flue gas desulfurization, in furnace calcium injection tail humidification desulfurization technology, flue gas circulating fluidized bed desulfurization technology, rotary spray drying flue gas desulfurization and other processes are commonly used in large power plants. The more mature, efficient and widely operated process is limestone gypsum flue gas wet desulfurization, which is suitable for high, medium and low sulfur coal. The limestone as desulfurizer is widely sourced and cheap, and can generate by-product gypsum, which can be fully used in the construction field. It is a desulfurization process selected by many thermal power plants.
In the desulfurization process, selecting a good desulfurizer is the key to absorbing sulfur dioxide. Limestone, as one of the desulfurizers with high desulfurization efficiency, is naturally the key factor affecting the whole desulfurization process. The smaller the particle size of limestone powder, the more conducive to the absorption of sulfur dioxide, and the faster the desulfurization and purification of flue gas after combustion. Therefore, selecting a set of energy-saving and performance limestone vertical pulverizer equipment becomes the best choice for desulfurization process in coal-fired power plants.
