摘要

In, thermocentrals, hydrocentrals and, since 1997, the Nuclear Central from Cernavoda has an important role in the electric energy. All production these producers of electric energy are interconnected forming the National Energetic System (NES), which has the tasks of overtaking and distribute the electric energy in the country as well as outside the country. Functionally, thermocentrals can work on solid fuel (coal), liquid fuel and gas fuel (natural gases, etc.). The lignite is the coal used in by the following centrals with steam turbines: Doicesti, Craiova, Oradea , Rogojelu, Turceni. The main characteristics of the lignite are: the water content 17-20 percent , the ashes content 20-45 percent and the inferior calorific power 12958-16302 kJ/ kg (3100-3900 kcal/kg). The mineral coal contains combustible substance (carbon, hydrogen, sulfur), ashes and water, this coal being used in the following thermocentrals: Paroseni, Craiova si Mintia. Among the main characteristics of the mineral coal we can mention: the water content 2- 10 percent , the ashes content 1-30 percent , the carbon content 40-80 percent , the sulfur content, higher than 2,5 percent . The energetic sector in is insured mainly by the thermo centrals (85 percent ) and and less by the primary energy sources. has 35 thermocentrals, but the energetic system infrastructure is older (47 percent of the thermocentrals are older than 20 years and 37 percent are between 11 and 20 years). This energetic sector is one of the main sources of air pollution with sulfur dioxide (SO2), azoth oxides (NOx), dust and carbon dioxide (CO_2). The thermocentrals in were not equipped for the pollution control because they were built in a time when the preoccupation on the environment was very low. The designing of the thermocentrals oversaw only the reduction of dust emissions. In the latest years after the rehabilitation, a part of the energetic centrals have been equipped with burning installations with low NOx emissions. No thermocentral is equipped for the keeping of SO2, and the used coal containes sulfur in big quantities. In this paper is analyzed the present situation of the atmospherical noxes resulted from the coal burning in the thermocentrals from Romania and also a few viable solutions for the reduction of their negative impact on the environment are proposed.
