DEVELOPMENT OF DESULFURIZATION PROCESS IN ROMANIA THERMAL POWER PLANTS

The purpose of this paper is an analysis of the SO2 pollution from Rovinari thermal power plant, before and after the installation of the desulphurisation facility, taking into account the unwanted effects upon the environment and human health. Modeling the dispersion of pollutants for the proximity areas of the Rovinari thermal power plant has been carried out by using the AUSTAL View specialized software within INSEMEX Petrosani. By putting the desulphurisation facilities into operation in phases, there is noticed the compliance with the enforced limit for the SO2 pollutant. By using the desulphurisation method the obtained coal combustion products are fly ash, bottom ash, boiler slag, fluidized bed combustion (FBC) ash, semi dry absorption product, flue gas desulphurisation (FGD) and gypsum. Calculation of the thermal power plants contribution to the emission ceiling applicable for sulphur dioxide may be based on the application of the relevant minimum rates of desulphurisation rather than on the emission limit values for sulphur dioxide.
