Abstract

Flue gas of coal boilers has required cleaning of sulphur dioxide with the efficiency of at least 96% to meet the requirements of Directive 2010/75/EU. Wet scrubbers with forced oxidation, which use limestone or lime as sorbent, are the most used desulphurisation plants at the world thermal power industry. They allow providing the efficiency of sulphur dioxide removal up to 98% and obtaining a gypsum as product. Lime is much more chemically active and expensive sorbent, than limestone, but it’s using requires a lot of time to dissolve the calcium sulphite scale. The use of particles of limestone, measuring up to 10 microns, at washing slurry wouldn't only allow providing the high efficiency of desulphurization but also reducing the risk of scaling at the upper part of the scrubber.
