Abstract
There is the problem of determining the polluted emissions in the case of a thermal power plant that uses coal as the main fuel in the Jiu Valley Mining Basin. The experimental determinations were performed at the points located behind the electrostatic precipitators and at the accessible points located behind the flue gas fans. These targeted mass flows and concentrations for indicators: O2, CO, CO2, NOx, SO2, dust: PM 10, PM 2.5, and total. The paper presents the values of average concentrations, determined experimentally, regarding pollutant emissions, including dust. The emissions for the analyzed energy groups were determined, for each category of polluting emissions comparative histograms were made.
Highlights
Coal based power plants in Romania are highly polluting through emissions of particles, Sulphur dioxide, nitrogen oxides, carbon dioxide and carbon monoxide
As a European Union member and signatory of the UNECE13/CLRTAP14 convention, Romania publishes annual estimates of atmospheric pollutants under the 2001/81/CE directive [1] regarding national emission limits and according to the protocols of the above conventions
Romania must reduce its annual emissions of gases that produce greenhouse and eutrophication effects and impact the ozone layer under 918 kt for Sulphur dioxide (SO2), 437 kt of nitrous oxides (NOx), 523 kt volatile organic compounds (NMVOC) and 210 kt of ammonia (NH3)
Summary
Coal based power plants in Romania are highly polluting through emissions of particles, Sulphur dioxide, nitrogen oxides, carbon dioxide and carbon monoxide. The member states must observe emission limits agreed in the Gothenburg Protocol through adopting the necessary measures to reduce the impact of anthropic activities upon the environment. Romania must reduce its annual emissions of gases that produce greenhouse and eutrophication effects and impact the ozone layer under 918 kt for Sulphur dioxide (SO2), 437 kt of nitrous oxides (NOx), 523 kt volatile organic compounds (NMVOC) and 210 kt of ammonia (NH3). The main objective of this paper is to determine the emissions of pollutants from a power station that uses coal with an average calorific capacity of 15392 kJ/kg from the Jiu Valley Basin. The experimental measurements include concentrations for the following indicators: O2, CO, CO2, NOx, SO2, and particulates such as: PM 10, PM 2,5 as well as total emissions
