The paper presents the results of many years of complex research issues related to the emission of fluorine compounds of iron and steel processes. They allowed to examine these processes used in raw materials in terms of the fluorine content and their impact on the amount of emissions of fluorine compounds to the air. Were determined by measuring the levels of concentration in flue gases and stack emissions of fluorine in the form of gaseous and solid compounds, including water-soluble components (considered to be toxic).

English title: Analysis of emission sources of fluorine compounds from the processes of ferrous metallurgy.

The article 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 …

Spalanie Odpadów W Procesie Skojarzonym Z Produkcją Klinkieru Cementowego - Problem Emisji Zanieczyszczeń, Robert Oleniacz

Robert Oleniacz

The paper presents a review of emissions of main gaseous pollutants (including acidic constituents), some organic compounds (including dioxins and furans), particulates and heavy metals from cement kilns burning waste fuels.

A widely employed method to reduce the cost of cement production is the substitution of traditional fuels used in cement kilns with alternative and waste-derived fuels. Cement industry offers the most acceptable method of waste (especially hazardous waste) thermal treatment and disposal at much lower cost than commercial incinerators. Characteristic for cement kilns high temperatures and long residence time of exhaust gas ensure almost complete destruction of organic compounds …

Multiscale Modeling Of Recrystallization, A. W. Godfrey, E. A. Holm, D. A. Hughes, M. A. Miodownik, Richard Alan Lesar

Richard Alan Lesar

We propose a multi length scale approach to modeling recrystallization which links a dislocation model, a cell growth model and a macroscopic model. Although this methodology and linking framework will be applied to recrystallization, it is also applicable to other types of phase transformations in bulk and layered materials. Critical processes such as the dislocation structure evolution, nucleation, the evolution of crystal orientations into a preferred texture, and grain size evolution all operate at different length scales. In this paper we focus on incorporating experimental measurements of dislocation substructures, misorientation measurements of dislocation boundaries, and dislocation simulations into a mesoscopic …

Spalanie Odpadów Niebezpiecznych W Piecach Cementowych. Część 2. Destrukcja Paliwa I Emisja Zanieczyszczeń, Robert Oleniacz Oct 1998

Spalanie Odpadów Niebezpiecznych W Piecach Cementowych. Część 2. Destrukcja Paliwa I Emisja Zanieczyszczeń, Robert Oleniacz

Robert Oleniacz

Conditions occurring in cement rotary kilns assure high destruction and removal efficiency (DRE) of the most stable substances, efficacious dry sorption of acid gases in the alkaline raw meal and heavy metals bounding in the clinker. Adequate operation of hazardous waste incineration in the process connected with cement clinker production does not cause increasing air pollutant emissions. Magnitude of the emissions often does not depend of this if there are using wastes in the cement kiln at all. The work presents a review of DRE levels and stack emissions for selected flue-gas constituents during hazardous waste co-combustion in cement kilns …

A widely employed method of reducing cement production costs is the substitution of traditional fuels with alternative and waste-derived fuels to heat the cement kiln. Cement industry offers the most acceptable method of hazardous waste incineration and co-combustion with significantly lower cost in comparison to incinerators. The high temperatures and long residence times inherent in the operation of cement kilns ensure the almost complete destruction of the organic compounds introduced together with waste fuels. This part of the article presents general characteristic of sort of waste incinerated in cement kilns, way of their charging, advantages and limitations of waste co-combustion …

Charge-Correlation Effects In Calculations Of Atomic Short-Range Order In Metallic Alloys, F. J. Pinksi, J. B. Staunton, Duane D. Johnson Jun 1998

Charge-Correlation Effects In Calculations Of Atomic Short-Range Order In Metallic Alloys, F. J. Pinksi, J. B. Staunton, Duane D. Johnson

Duane D. Johnson

The “local” chemical environment that surrounds an atom directly influences its electronic charge density. These atomic charge correlations play an important role in describing the Coulomb and total energies for random substitutional alloys. Although the electronic structure may be well represented by a single-site theory, such as the coherent potential approximation, the electrostatic energy is not as well represented when these charge correlations are ignored. For metals, including the average effect from the charge correlation coming from only the nearest-neighbor shell has been shown to be sufficient to determine accurately the energy of formation. In this paper, we incorporate such …

Cellular Automaton Modeling Of Alloy Solidification Using Local Anisotropy Rules, Ralph E. Napolitano, T. H. Sanders Jr. Apr 1998

Cellular Automaton Modeling Of Alloy Solidification Using Local Anisotropy Rules, Ralph E. Napolitano, T. H. Sanders Jr.

Ralph E. Napolitano

The evolution of dendritic morphology is simulated for a binary alloy using a two-dimensional cellular automaton growth algorithm. Solute diffusion is modeled with an alternate-direction implicit finite difference technique. Interface curvature and kinetic anisotropy are implemented through configurational terms which are incorporated into the growth potential used by the automaton. The weighting of the anisotropy term is explored and shown to be essential for overcoming grid-induced anisotropy, permitting more realistic development of dendritic morphologies. Dendritic structures are generated for both uniform and directional cooling conditions.
