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 …

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 …

Emisja Związków Siarki Z Procesu Wielkopiecowego, Marian Mazur, Marek Bogacki, Robert Oleniacz Nov 1996

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 …

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 …

Electronic Origins Of Ordering In Multicomponent Metallic Alloys: Application To The Cu-Ni-Zn System, J. D. Althoff, Duane D. Johnson, F. J. Pinski, J. B. Staunton Apr 1996

Electronic Origins Of Ordering In Multicomponent Metallic Alloys: Application To The Cu-Ni-Zn System, J. D. Althoff, Duane D. Johnson, F. J. Pinski, J. B. Staunton

Duane D. Johnson

We investigate the ordering tendencies of the fcc Cu-Ni-Zn system using a recently developed first-principles, density-functional-based theory of atomic short-range order (ASRO) in disordered substitutional alloys of an arbitrary number of components. We find for the binary alloys a variety of effects which should lead to competition in the ternaries: commensurate ordering (Ni-Zn), long-period ordering (Cu-rich Cu-Zn), and clustering (Cu-Ni), in agreement with experiment. We calculate the ASRO of various disordered ternary alloys (as described by the Warren-Cowley pair-correlation function) and discuss its relationship to the electronic structure of the binary and ternary disordered alloys. We find [100]-type ASRO over …

By adapting a scanning force microscope to operate at frequencies above the highest tip–sample resonance, the sensitivity of the microscope to materials’ properties is greatly enhanced. The cantilever’s behavior in response to high‐frequency excitation from a transducer underneath the sample is fundamentally different than to its low‐frequency response. In this article, the motivations, instrumentation, theory, and first results for this technique are described.
