Problem Niekontrolowanego Spalania Odpadów I Pozostałości Roślinnych W Obszarze Wiejskim Na Wybranym Przykładzie, Robert Oleniacz, Barbara Bacik

Robert Oleniacz

This paper presents the results of surveys on the problem of uncontrolled burning of waste in domestic stoves and boilers for central heating and open burning of plant residues in rural areas. The questionnaires were conducted among the inhabitants of one of Polish village (Łąkta Dolna), located in the Malopolska province, in the submontane area. The study comprised 80.2% of all households. As is clear from conducted surveys waste were burned in more than 80% of surveyed houses and more than half of respondents admitted to the open burning of plant residues. The percentage of people burning waste and plant …

Pomiary Liczby I Wielkości Cząstek Aerozoli W Powietrzu Miejskim Z Wykorzystaniem Metody Optoelektronicznej, Marek Bogacki, Robert Oleniacz, Marian Mazur, Monika Dziugieł

In the paper some measurement results of number and size for aerosols particles suspended in air achieved using infrared particle sizer IPS-P (Kamika Instruments) with isokinetic air sampling method were presented. In IPS-P analyzer, with measuring range from 0,4 to 300 μm, is applied optical/electronic measurement method which is determined by dimensions of measurement space by aerosols particles motions in a parallel radiation beam. The research was conducted on the roof of four-storey building in Krakow for various meteorological conditions. Results achieved for measured parameters were analysed in terms of selected meteorological factors influence.

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

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

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 …
