In this paper the examination results of chemical and phase composition as well as wastes graining from the semi-dry flue
gas desulfurization (FGD) have been presented. The wastes contain mainly semi-hydrate calcium sulfite and calcium sulfate.
The phase composition changes of wastes at the temperature of 350 and 600°C have been determined. On the basis of carried
out examinations, possibilities of flue gas desulfurization wastes utilization in building materials production (sulfite and
anhydrite cement) are proposed.

DTA, TG and XRD methods were used for the determination of by-product - obtained during flue gas desulfurization by means
of introduction of dehydration - resisting sludge from water decarbonization system. Analysis results enabled the development
and application of sludge utilization technology by means of semi-dry flue gas desulfurization in 'Siersza' power plant.
