Method for reducing the amount of a sulfur dioxide in a flue gas resulting from the combustion of a fossil fuel

摘要

A process for removal of sulfur dioxide from a flue gas. An alkaline admixture is coated with a coating agent that improves dispersability and delays calcination of the alkaline admixture within a combustion zone and results in a coated alkaline admixture. The coated alkaline admixture is introduced to the boiler to create a reaction that reduces the amount of sulfur dioxide from the flue gas.
