Emisja Zanieczyszczeń Ze Spalania Odpadów Ściekowych W Piecu Półkowym, Robert Oleniacz, Marian Mazur, Marek Bogacki

Robert Oleniacz

The article presents incineration tests of silty-tar sludge produced in the wastewater treatment plant for coke industry. Sewage sludges were incinerated in a full-scale multiple hearth incinerator equipped with a wet flue-gas cleaning system (alkaline scrubber). Measurements of air pollutant emissions were carried out both before and after the cleaning system. The obtained results allow to conclude that the thermal utilization of sewage sludge in this type of installation might be just a little cumbersome for the environment, using the appropriate equipment for the purification of exhaust gases. The paper also specifies minimum exhaust gas cleaning performance that guarantees compliance …

Wdrażanie Monitoringu Zanieczyszczeń Powietrza Atmosferycznego W Kielcach, Marian Mazur, Robert Oleniacz, Marek Bogacki

Robert Oleniacz

Assumptions for regional environmental monitoring in the province of Kielce were developed as early as 1992. Since the beginning of particular attention were monitoring the air. The article presents the next step in the implementation of this monitoring, associated with verification of the location and the measuring range of points to measure the concentrations of air pollutants in Kielce. As a result of analysis and calculations, it was found that the original location is not always correct and does not reflect the spatial differentiation of pollutant concentrations. The proposed changes in the position of monitoring points or measurement methods were …

Zastosowanie Metody Obliczeniowo-Pomiarowej Do Oceny Stanu Zanieczyszczenia Powietrza W Nowym Sączu, Marian Mazur, Marek Bogacki, Robert Oleniacz

Robert Oleniacz

Assessment of the state of air pollution in the urban area is a difficult and complex task. Depending on the method of assessment the procedure requires a comprehensive research and calculations of air emissions from all sources occurring in the area and the use of atmospheric dispersion models or large-scale implementation of direct measurements of air pollutant concentrations. Both of these methods may also be applied simultaneously to their mutual verification.

The article presents the results of such a comprehensive assessment of air pollution on the example of the city of Nowy Sacz (Poland). This involved determining the emissions of …

Obliczanie Emisji Par Węglowodorów Z Przemysłu Rafineryjnego, Marian Mazur, Robert Oleniacz, Marek Bogacki

Robert Oleniacz

The negative effects of the refining industry for ambient air quality is mainly related to emissions of hydrocarbon vapors. Calculation methodology and estimates, the level of emissions from several years has been the research subject of many institutions and environmental agencies, including The Oil Companies’ European association for health, safety and environment in refining and distribution (CONCAWE) and American Petroleum Institute (API).

The article describes the main sources of emissions of hydrocarbons occurring in a typical refinery. In summary form also shows how to calculate the volume of a mixture of hydrocarbons emissions from these sources based on empirically validated …

Badania Emisji Chlorowodoru I Związków Fluoru Podczas Spalania Odpadów Niebezpiecznych, Marian Mazur, Robert Oleniacz, Marek Bogacki

Robert Oleniacz

The paper presents the results of measurements of the concentration of hydrogen chloride (HCl) and fluoride compounds (as HF) in raw and purified combustion gases discharged from the incineration of selected hazardous wastes. The study included two installations operating on an industrial scale: a multiple hearth furnace and a rotary kiln incinerator equipped with a single wet flue gas cleaning systems. In the multiple hearth furnace was being incinerated sludge from coke industry. In the rotary kiln were being incinerated coal (coke) tars, contaminated cleaning rags, sawdust, used gloves, outdated pharmaceuticals and medicines, hospital waste, waste paints, varnish and lubricant, …

The work presents the problem of management and thermal treatment of medicines and hospital wastes and investigation results of incineration of these waste in the full-scale rotary kiln with wet gas cleaning equipment (alkaline scrubber). On the basis of measurements of air pollutant concentrations in combustion gases, maximum dose of these wastes in the feed to the kiln was specified in order to ensure a relatively low stack emissions using the hypothetical high-efficiency flue-gas treatment system.

Emisja Związków Siarki Z Procesu Wielkopiecowego, Marian Mazur, Marek Bogacki, Robert Oleniacz

Robert Oleniacz

The paper describes the problem of the presence of sulfur in the blast furnace process and identifies emission sources of sulfur compounds in this process. On the basis of the measurements and calculations, the types and quantities of these compounds emitted to the air were determined. It was found that pig iron smelting in a blast furnace causes emissions of COS, SO2 and H2S. These emissions occur by losses of blast furnace gas (COS and SO2), transport of blast furnace slag inside the furnace hall (SO2) and treatment of the slag by granulation (H2S). However, the most important are only …

Wpływ Komponentów Alkalicznych W Procesach Spiekania I Wielkopiecowym Na Technologię I Emisję Zanieczyszczeń, Marian Mazur, Ryszard Benesch, Andrzej Łędzki, Robert Oleniacz

Robert Oleniacz

The paper presents the impact of alkali metals on sintering and blast furnace processes and air pollutant emissions including particulate matter. On the basis of the balance calculations, it was found that the main source of alkali (Na2O and K2O) in the sintering process is a raw mixture unweathered. The calculations showed that the level of dust emissions from the sinter strand to a large extent depends on: the total alkali content in a mixture of sinter, ash content in coke breeze, K2O concentration in coke ash and alkalinity of the produced sinter. Alkali metals are introduced into the blast …

On Velocity-Conditioned Scalar Mixing In Homogeneous Turbulence, Rodney O. Fox

Rodney O. Fox

Scalar mixing models are required to modelturbulent molecular mixing in full probability density function (pdf) simulations of turbulent reacting flows. Despite the existence of direct numerical simulation (DNS) data suggesting the contrary, most scalar mixing models assume that molecular mixing is independent of the instantaneous velocity, i.e., 〈D∇2φ|V,ψ〉=〈D∇2φ|ψ〉. Since in a joint velocity, composition pdf calculation the velocity is known, this assumption is unnecessary and leads to a lack of local isotropy in the scalar field. Moreover, since velocity conditioning offers a numerically tractable approach for including the effects of local anisotropy and mean velocity gradients on scalar mixing, it …

Monitoring Zanieczyszczeń Powietrza Wokół Elektrowni "Jaworzno Iii", Marian Mazur, Robert Oleniacz, Marek Bogacki, Ryszard Kozakiewicz

Robert Oleniacz

The article presents the concept of system of monitoring of air pollution around the Power Plant "Jaworzno III" in Jaworzno (Poland), whose objective is to evaluate the impact of this object on air quality. This system is based on a few measuring points and a mobile station should also allow for the assessment of ecological effects associated with the use of low-emission burners in power boilers (reduction of NOx emission) and run the wet installation of flue gas desulfurization (reduction of SO2 emission). An additional aim of the measurements is to identify the possible effects of a changes in the …

Snow Pack Temperature Sensor, M. Shamshi, Raman Attri, V. Sharma

Raman K. Attri

The study of snow hydrological characteristics plays the major part in forecast of snow-melt, snow run-off water of rivers, potential release of snow avalan'che and climatic changes. Increasing importance of study of snow hydrology has lead to the development of many snow sensors which monitors physical parameter of snow. Design of such snow sensors has been a difficult job because of harsh environmental conditions. This paper present the design considerations and performance characteristics of snowpack temperature profile sensing probe. This probe provides temperature gradient and temperature distributions within the snow-pack, and ground at different depths. The information on temperature distribution …
