Limestone in flue gas desulphurization in oxygen-enriched atmospheres. Part I. The effect of CO2 on limestone calcination

The article describes the testing of four selected samples of limestone originating from four commercially exploited deposits. The tests of sorbents included a physicochemical analysis and calcination in different atmospheres. The main aim of the tests was to determine the possibilities for using limestone during combustion in oxygen-enriched atmospheres. Tests in a synthetic flue gas composition make it possible to assess the possibility of CaC03 decomposition in atmospheres with an increased C02 concentration.
