Sulfur dioxide emissions are controlled by feeding limestone into the boiler; last year, 62,500 tCaCO 3 were used for that purpose. NO x emissions from a CFB combustion unit are only around one fifth of those produced by pulverized coal combustion as the combustion occurs at lower temperature and thus less NO x is formed.
