CLEANING OF FLUE GASES IN THERMAL POWER PLANTS

Furthermore, flue gases need to be exposed to process water in order to achieve a high level of scrubbing process. Process water is delivered directly to the reactor chamber. The humidity of flue gases in the reactor chamber is critical. It is determined with theWet lime scrubbing | EMISThis flue gas cleaning technique is mainly used for desulphurisation of flue gases, while other acid-forming components are also bonded. During wet lime injection, a slurry of limestone (CaCO 3 ) is sprayed into the spray column.High Temperature Desulfurization of Flue Gas Using .Abstract Removal of sulfur dioxide from flue gas is mainly accomplished by contacting the flue gases with calcium-based (limestone, lime and hydrated lime) sorbents which show remarkable sulfur dioxide scavenging abilities.
