Assessing the environmental pollutant vector of combustion gases emission from coal-fired power plants

摘要

Within the present industrial metabolism, electric and thermal energy production is one of the main consumers of fossil fuels. Coal is a natural resource and fossil fuel used in the coal-fired power plants in Romania. Unfortunately, beyond the environmental depletion, the problems caused by the environmental releases in operation of these power plants are also related to human health impact. This paper highlights some of these problems, analyzing the pollutant vector of combustion emissions and the specific physical parameters associated to a coal-fired power plant in Romania. The environmental pollutants belonging to combustion gases vector, as sulfur dioxide SO_2, nitrogen oxides NO_X, particulate matter PM, and carbon dioxide CO_2 have been analyzed for the Energetic Power Plant of Turceni - Romania. Mathematical models of environmental pollutant vector, estimating the emission factors specific to fossil fuel combustion process have been applied for the thermo-electrical blocks on 330 MW of Turceni power plant For each combustion gases component of pollutant vector, the results with regard to emission factor and pollutant concentration are presented in this study. Also, the Projection in the Mirror of the combustion gases pollutant vector had allowed an evaluation of mass concentration of the ash in the combustion gases quill. In this case study for the thermoelectric blocks of 330 MW of Turceni power plant, the projection in mirror is developed for distances of 300 meters, and for modelling the ascendant smoke quill according to this projection in mirror, it has been adopted the FDP pattern - probability density function, elaborated by Weil. Accordingly, the nomograms of ash-particulate matter pollutant have been simulated.
