Types of desulfurization equipment

At present, there are three main desulfurization methods in industry: desulfurization before combustion, desulfurization during combustion and desulfurization after combustion. There are more than a dozen desulfurization processes. Different processes will use different production systems, and the selection of desulfurization equipment will be different. At present, limestone-gypsum desulfurization process is the most widely used desulfurization technology in the world, and about 90% of flue gas desulfurization devices used in thermal power plants in Japan, Germany and the United States adopt this process. Therefore, the desulfurization equipment needed for this process is emphasized.
