Współspalanie Odpadów W Suchym Piecu Cementowym A Emisja Dwutlenku Siarki I Chlorowodoru, Robert Oleniacz Jun 2010

Współspalanie Odpadów W Suchym Piecu Cementowym A Emisja Dwutlenku Siarki I Chlorowodoru, Robert Oleniacz

Robert Oleniacz

The paper presents an assessment of the impact of waste co-combustion in a cement kiln on air emissions of HCl and SO2 recorded continuously. The subject of the research was cement kiln (dry method) with a capacity of 8500 Mg/day, equipped with a four cyclone heat exchangers and a calciner with an additional chamber for co-incineration. In the analysed period alternative fuels (mainly waste) were used in various amounts ranging up to about 35 kg / Mg clinker (with the heat substitution up to 20%) in the kiln and calciner. Chlorine and sulfur inputs to the process were up to …


Assessment Of The Impact Of Using Alternative Fuels In A Cement Kiln On The Emissions Of Selected Substances Into The Air, Robert Oleniacz Jan 2010

Assessment Of The Impact Of Using Alternative Fuels In A Cement Kiln On The Emissions Of Selected Substances Into The Air, Robert Oleniacz

Robert Oleniacz

The chapter presents the results of analyses concerning the impact of using alternative fuels in one of the Polish cement plants on the volume of continuously measured emissions into the air for the following substances: carbon dioxide (CO2), carbon monoxide (CO), nitric oxides (NOx), sulphur dioxide (SO2), hydrogen chloride (HCl), gaseous and volatile organic compounds expressed as total organic carbon (TOC), and total dust. The analyses covered a 15-month period of the operation of a dry cement kiln, approximately 100m-long, equipped with four-stage cyclone exchangers and a calciner, constituting an additional chamber for waste co-combustion. The results obtained confirmed the …


Emisja Zanieczyszczeń Pyłowo-Gazowych Z Procesu Wypalania Półproduktów Grafitowych W Piecu Tunelowym, Marek Bogacki, Robert Oleniacz, Marian Mazur, Przemysław Szczygłowski Jan 2010

Emisja Zanieczyszczeń Pyłowo-Gazowych Z Procesu Wypalania Półproduktów Grafitowych W Piecu Tunelowym, Marek Bogacki, Robert Oleniacz, Marian Mazur, Przemysław Szczygłowski

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 …
