Limestone, quicklime, slaked lime – which one is the best as a flue gas desulfurization agent?
Thread Content
I would like to ask about flue gas desulfurization agents: what are the differences between limestone, quicklime, and slaked lime? It would be great if you could explain the ratios used in flue gas treatment, the desulfurization environment, the effectiveness of these agents, and which one is best to use when there is dust present in the flue gas.
Carbon dioxide and nitrogen oxides are also present in the flue gas.
What size boiler? Coal-fired boiler, circulating fluidized bed?
Technical specifications are available on the official website of the Ministry of Ecology and Environment
It’s about 55 meters long and 4 meters in diameter, used for calcining ore
Calcium hydroxide is more effective than limestone
Slaked lime slurry reacts with the high concentration of CO2 in flue gas；
