Abstract  

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.

Abstract  

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.
