In the multiple hearth furnace an industrial sewage sludge (from coke industry) was being incinerated. In the rotary kiln such wastes were being incinerated as: waste paints, varnish and lubricant, coal tars waste, contaminated cleaning rags, sawdust and used gloves, waste resins and plastics, rubber waste, outdated pharmaceuticals and medicines, and hospital waste. The research allowed us to determine the levels of pollutant concentrations …

Zastosowanie Modelu "Skrzynki" Do Oceny Poziomu Stężeń Zanieczyszczeń Komunikacyjnych W Przyziemnej Warstwie Atmosfery, Marek Bogacki, Marian Mazur, Robert Oleniacz

Robert Oleniacz

Road transport is an essential source of nitrogen oxides (NOx), carbon monoxide (CO) and reactive hydrocarbons (RHC) emissions to atmosphere. Quantity and chemical constitution of emitted substances and meteorological conditions determine the level of ozon (O3) concentration forming as a result of photochemical reactions. The method presented in the paper consists in designation of quantity and chemical constitution of substances emitted from mo-bile sources and special mathematical modeling of physical and chemical transformations that take place in the lowest atmospheric layer.

Both storage and thermal disposal of sewage sludge from industrial wastewater treatment plants are a significant source of air pollutant emissions. The study included the sludge generated in the coke-chemical industry. The paper presents the results of measurements of emissions of selected substances during storage of the waste in a closed storage hall with natural ventilation and during incineration of the mechanically dewatered sludge in a multiple hearth furnace.

Spalanie Odpadów Poszpitalnych I Farmaceutycznych W Piecu Obrotowym / Incineration Of Hospital And Pharmaceutical Wastes In A Rotary Kiln Incinerator, Robert Oleniacz, Marian Mazur, Marek Bogacki

Robert Oleniacz

The paper presents selected results of research on hospital and pharmaceutical waste incineration in a full-scale rotary kiln with variable loads of the kiln. As part of these studies measurements of air pollutant concentrations in flue gases and leaching tests of solid combustion products were carried out. Based on these studies, the maximum dose of hospital and pharmaceutical waste was proposed in the mixture with industrial wastes, which does not cause excessive air emissions. The average emission factors for the waste mixture loading were also determined.

Robert Oleniacz

The paper presents the procedure and the results of the environmental impact assessment for the induction furnace installed in the company "Krakodlew" S.A. in Krakow (Poland). This furnace will allow heating and keeping the liquid feed (pig iron) and adjust the chemical composition, which will allow for the production of high-quality heavy castings. The need to perform an environmental impact assessment for objects of this type results from the binding legal regulations in Poland. The analysis included all the main components of the environment: air, soil, vegetation, soil and water environment, land surface and acoustic climate. It was found that …

Segregation Of Bismuth To Triple Junctions In Copper, K.-M. Yin, Alexander H. King, T.E. Hsieh, F.-R. Chen, J.J. Kai, L. Chang

Alexander H. King

Bismuth segregation in copper has been studied using energy-dispersive X-ray spectrometry (EDX) in a JEOL 2010F transmission electron microscope. In addition to the expected solute enrichment at grain boundaries, we have observed extremely high concentrations of bismuth at certain triple junctions, with significantly greater enrichment factors than in the adjacent grain boundaries. It is shown here that the triple junction segregation is a function of the parameters of the grain boundaries at the triple line, and existence of this type of segregation implies that the affected triple junctions embody excess free energy. At least one of the observed triple junctions …

Vibrational Spectra In Ordered And Disordered Ni3al, Jeffrey D. Althoff, Dane Morgan, Didier De Fontaine, Mark Asta, S. M. Foiles, Duane D. Johnson

Duane D. Johnson

We calculate the vibrational density of states (DOS) and corresponding thermodynamic properties of L12 ordered and disordered Ni3Al in the quasiharmonic approximation using the embedded-atom method. Vibrational and thermodynamic properties, including vibrational entropy differences between ordered and disordered states, are found to be in good agreement with experiment. The DOS of the configurationally disordered alloy resembles a broadened version of the DOS of the L12 phase, not a one-atom per cell fcc DOS, and is shifted downward in frequency because the disordered state has a larger volume than the ordered phase. Calculations of the projected DOS indicate that high-frequency modes …

Green And Ampt Infiltration With Redistribution, Fred L. Ogden

Fred L. Ogden

Distributed, physically based watershed and irrigation advance models require robust infiltration estimation capabilities. The empirical Green and Ampt (GA) equation of infiltration is a popular method for estimating infiltration. The GA parameters have physical basis and considerable prior research has focused on relating these parameters to soil textural classification. However, the original GA method is limited in that it is applicable only for a single ponding period. An explicit Green and Ampt redistribution (GAR) technique is developed herein to estimate interstorm redistribution of soil water and allow multiple ponding simulations using the GA methodology. Soil water redistribution during interponding periods …

Robert Oleniacz

The paper presents the concept of air pollution monitoring around the Power Plant "Jaworzno III" (Poland) with the use of the mobile station. Aim of the new monitoring system is to provide information about the current state of air pollution and to enable an assessment of the environmental implications of the use of low-emission burners, run the installation of flue gas desulphurisation and changes in the way of releasing flue gases into the atmosphere. Due to economic, technical and practical the monitoring system was based on a single mobile station. Measurements will be carried out in a random scheme at …

Experimental And Theoretical Investigations Of Order-Disorder In Cu2almn, Duane D. Johnson, M. Asta, J. J. Hoyt, B. C. Chakoumakos, S. T. Misture, J. D. Althoff, R. Mccormack

Duane D. Johnson

A combination of X-ray and neutron powder diffraction has been used to measure the two long range order parameters vs. temperature below the disorder-B2 transition in the ternary alloy Cu2 AlMn. The results indicate that at temperatures just below the critical point the Al + Mn sublattice is enriched in Al. First-principles calculations based on only the atomic numbers of Cu, Mn and Al support the experimentally-observed preference of Al for the Al + Mn sublattice, and reveal the interplay between the constituent binary systems that gives rise to this behavior.

Stiffness Of Measurement System And Significant Figures Of Displacement Which Are Required To Interpret Adhesional Force Curves, Nancy Burnham, Kunio Takahashi, Hubert Pollock, Tadao Onzawa

Nancy A. Burnham

Force curves obtained from an elastic contact theory are shown and compared with experimental results. In the elastic contact theory, a pin-on-disk contact is assumed and the following interaction are taken into consideration; (i) elastic deformation, (ii) the specific energy of adhesion in the area of the contact, which is expressed as the difference between the surface energies and the interface energy, (iii) the long-range interaction outside the area of contact, assuming the additivity of the Lennard-Jones type potential, and (iv) another elastic term for the measurement system such as the cantilever stiffness of an atomic force microscope (AFM). In …

Sensors For Site-Specific Management, Stuart J. Birrell, J. W. Hummel, K. A. Sudduth

Stuart J. Birrell

Site-specific management (SSM, also known as precision farming, precision agriculture, prescription farming, etc.) is a management strategy that seeks to address within-field variability and to optimize inputs such as pesticides and fertilizers on a point-by-point basis within a field. By reducing over-application and under-application of nutrients and pesticides, this strategy has the potential to improve profitability for the producer and also to reduce the threat of groundwater or surface water contamination from agrichemicals. SSM is being adopted by innovative producers across the country. Agricultural equipment manufacturers, farm input suppliers, and a host of other businesses are working along with publicsector …
