ABSTRACT
The need for clean coal technologies to reduce the adverse environmental impact of coal combustion products has been grounded. The article deals with information concerning present and future technologies, directed towards the struggle against air pollution by SO2, produced during coal combustion. Their classification and critical rating from economical and technological points of views (including those developed by authors) have been performed. The method of comparing the effectiveness of flue gas desulphurization (FGD) processes and technologies of coal preventive desulphurization were offered.
