Co-Incineration Of Large Quantities Of Alternative Fuels In A Cement Kiln – The Problem Of Air Pollutant Emissions, Robert Oleniacz, Magdalena Kasietczuk Jan 2012

Co-Incineration Of Large Quantities Of Alternative Fuels In A Cement Kiln – The Problem Of Air Pollutant Emissions, Robert Oleniacz, Magdalena Kasietczuk

Robert Oleniacz

Over the last few years, a significant increase in the use of alternative fuels in the Polish cement industry has been observed. These are mainly waste and waste-derived fuels. The national leader in this field is Chełm cement plant (Poland), with the share of alternative fuels in the cement kiln heat balance reaching in 2012 the level of 78.5%. In this paper, an analysis of the emission rate of air pollutants from cement clinkering process in the above-mentioned cement plant in the years 1998–2012 was carried out, using the results of continuous and periodic measurements. The compliance with the emission …


Air Pollution Emissions During Baking Of Semi-Finished Graphite Products In A Tunnel Furnace, Marek Bogacki, Robert Oleniacz, Marian Mazur Jan 2012

Air Pollution Emissions During Baking Of Semi-Finished Graphite Products In A Tunnel Furnace, Marek Bogacki, Robert Oleniacz, Marian Mazur

Robert Oleniacz

The baking of semi-finished graphite products in a tunnel furnace is the source of many air pollutants present in both the gaseous and solid phases. The goal of this study was to assess emission rates into the air of the substances such as: CO, NOx, SO2, H2S, CH4, aliphatic hydrocarbons up to C6, benzene and its homologues (BTEX), total dust and tar substances, and polycyclic aromatic hydrocarbons (PAHs) contained in the dust. The research showed a small time-dependence of the emission rates for the majority of the substances analysed, which is, to a large extent, a result of the long …


Ocena Efektów Modernizacji Systemu Oczyszczania I Ewakuacji Spalin Na Wybranych Przykładach, Robert Oleniacz, Marcelina Groborz, Michał Ożóg Dec 2011

Ocena Efektów Modernizacji Systemu Oczyszczania I Ewakuacji Spalin Na Wybranych Przykładach, Robert Oleniacz, Marcelina Groborz, Michał Ożóg

The paper presents an assessment of changes in air emissions and impacts on air quality resulting from the modernization of flue gas cleaning and evacuation in two Polish coal-fired power plants. These modernizations were associated with the construction of flue gas desulphurisation systems and use for discharging desulphurized gases separate stacks with a height of 120 m. On the basis of analyzes and atmospheric dispersion modeling, it was found that the changes in the effective height of emitters (the apparent point of emission), due to additional reducing of flue gas volume in existing chimneys, caused that important ecological effects of …
