Abstract:
The degassing and dedusting mechanism of La and Ce during non-vacuum melting process of Cu-Cr-Zr alloy were analyzed by thermodynamics. The gibbs free energy changes of reactions of La and Ce with some impurties such as O2, H2, S, P and Si, were calculated to discriminate the possibility of reaction during the melting process, respectively. In addition, the effect of La and Ce on microstructure and properties were studied. The results show that La and Ce can react with O2, H2, S, P and Si, which improves the effect of degassing and dedusting remarkably; the addition of La and Ce can eliminate pine-tree crystal, fine grain and clear grain bourdary.

Information on the use of tubular radiation recuperators on melting bubble furnaces is presented. The reasons that subsequently affect deterioration of the recuperators performance have been analyzed. New structure of the recuperators, in which a hanging top collector with a counterweight and appropriate loop-type expansion joints are applied to prevent uncontrolled deformation of heat-receiving pipes, have been designed based on the analysis of the operation of recuperators of melting bubbling furnaces. New design allows to increase efficiency of the recuperator application, cleaning and repair of the pipes are possible without dismantling of the stack brick work. Bibl. 6, Fig. 5, Tab. 2.

Abstract:
This work has been a combined experimental and numerical modeling effort aimed to help in the understanding of heat transfer processes when melting aluminium. In addition a newly developed type of oxy-fuel burner was investigated. Objectives set for this project include improving energy efficiency in a typical industry furnace used today and looking at possible new technology to realize higher efficiencies than normally obtained. As a starting point a literature review was done to get an overview of furnaces and technology used in aluminium remelting and recycling. The most commonly used furnace today for aluminium melting and remelting is the reverberatory furnace which was the focus of this work as well. Understanding the interaction of parameters influencing heat transfer and quantifying how heat is transferred in the furnace are key elements to be able to optimize energy efficiency. Reverberatory furnaces are usually heated by gas burners, more specifically with cold air as oxidizer. Recent developments in burner technology using pure oxygen as oxidizer has showed some promising results and was investigated in experiments and numerical models. Melting experiments were carried out in a controlled environment in a 500 kg laboratory scale furnace as a basis for understanding the heat transfer mechanisms and quantifying radiation and convection contributions when melting aluminium. The experiments also served as a reference for a numerical 1-dimensional heat transfer model along with more advanced 3-dimensional computational fluid dynamics (CFD) models using a commercial software package. Phenomena as turbulent flow, combustion, convection, conduction and radiation were included in the models along with latent heat release when melting metal. The influence and impact of physical parameters on the heat transfer could be determined in the numerical models and provided a more detailed analysis of the processes in the furnace. A newly developed Low Temperature Oxy-fuel (LTOF) burner was investigated and compared to a conventional cold air-fuel burner in a pilot scale furnace. Measurements of flame and furnace temperatures, gas composition and heat fluxes were done for both burners at two different input levels. Heating experiments of aluminium samples were performed to look at the difference between the burners for aluminium heating and melting applications. 3-dimensional CFD models were developed to determine unknown quantities such as metal emissivity and quantification of radiation and convection heat transfer. The experiments also confirmed the validity of the numerical models. Finally a full scale reverberatory industry furnace was modeled using a 3-dimensional CFD model. The air-fuel burners currently installed in the furnace was replaced by LTOF burners in the numerical model. The performance was compared to a previously published numerical model of the same furnace using air-fuel burners for two different metal configurations in the furnace. The influence of parameters such as burner input, metal emissivity, furnace wall emissivity and a dross layer was studied. The key factor when making improvements in furnaces is understanding the fundamental heat transfer processes in existing technology. The experimental and numerical modeling work presented in this thesis has studied these phenomena and created a basis from which further investigations into furnace efficiency in aluminium remelting and recycling can be done. The performance of a new type of burner was also analyzed and explained through experiments and modeling.

Abstract:
Thesis (MScEng (Process Engineering))--Stellenbosch University, 2008.
The furnace at Polokwane is designed to treat high chromium containing concentrates which requires higher smelting temperatures to prevent or limit the undesirable precipitation of chromium spinels. The furnace has therefore been designed to allow for deep electrode immersion with copper coolers around the furnace to permit the operation with the resulting higher heat fluxes. Deep electrode immersion has been noted to result in dangerously high matte temperatures. Matte temperatures however can be influenced by a number of furnace factors which emphasize the need to understand the energy distribution inside the furnace. Computational fluid dynamics (CFD) has therefore been identified to analyze the flow and heat profiles inside the furnace. The commercial CFD software code Fluent is used for the simulations. Attention has been given only to a slice of the six-in-line submerged arc furnace containing two electrodes or one pair while focusing on the current density profiles, slag and matte flow profiles and temperature distribution throughout the bath to ensure the model reflects reality. Boundary conditions were chosen and calculated from actual plant data and material specifications were derived from previous studies on slag and matte. Three dimensional results for the current, voltage and energy distributions have been developed. These results compare very well with the profiles developed by Sheng, Irons and Tisdale in their CFD modelling of a six-in-line furnace. It was found the current flow mainly takes place through the matte, even with an electrode depth of only 20% immersion in the slag, but the voltage drop and energy distribution still only take place in the slag. Temperature profiles through-out the entire modelling domain were established. The vertical temperature profile similar to Sheng et al. 1998b was obtained which shows a specifically good comparison to the measured temperature data from the Falconbridge operated six-in-line furnace. The temperature in the matte and the slag was found to be uniform, especially in the vertical direction. It has been found that similar results with Sheng et al. (1998b) are obtained for the slag and matte velocity vectors. Different results are, however, obtained with different boundary conditions for the slag/matte interface and matte region; these results are still under investigation to obtain an explanation for this behaviour. The impact of the bubble formation on the slag flow was investigated and found to be a significant contributor to the flow. With the bubble formation, it is shown that possible ‘dead zones’ in the flow with a distinctive V-shape can develop at the sidewalls of the furnace with the V pointing towards the centre of the electrode. This behaviour can have a significant impact on the point of feed to the furnace and indirectly affect the feed rate as well as the settling of the slag and matte. These results are not validated though. Different electrode immersions were modelled with a constant electrical current input to the different models and it was found that the electrode immersion depth greatly affects the stirring of the slag in the immediate vicinity of the electrode, but temperature (which determines the natural buoyancy) has a bigger influence on the stirring of the slag towards the middle and sidewall of the slag bath. The sensitivity of the model to a different electrode tip shape with current flow concentrated at the tip of the electrode was also modelled and it was found that the electrode shape and electrical current boundary conditions are very important factors which greatly affect the voltage, current density and temperature profiles through the matte and the slag. A detailed investigation to determine the electrode tip shape at different immersions, as well as the boundary conditions of the current density on the tip of the electrode is necessary as it was proven that the model is quite sensitive to these conditions. Several recommendations arose from this modelling work carried out in this investigation. Time constraints, however, did not allow for the additional work to be carried out and although valuable results were obtained, it is deemed to be a necessity if a more in-depth understanding of furnace behaviour is to be obtained. Future work will include the validation of the results, understanding the liquid matte model, investigating the MHD effects and modelling different furnace operating conditions.

Abstract:
A computational fluid dynamics code developed at Argonne National Laboratory was used to simulate turbulent mixing, combustion reaction, radiation heat transfer, and pollutant kinetics of the combustion flow in industrial melting furnaces. The code employs an integral approach to incorporate a lumped combustion reaction model in the flow calculation and a separate hybrid technique to perform pollutant kinetics calculations for NOx and soot. The code validated with experimental data collected from industrial furnaces, was used to evaluate the impacts of burner operation conditions on the energy efficiency of furnaces. The results indicate that the furnace configuration has a significant effect on the combustion efficiency; the burner injection velocity affects the flow penetration and the species mixing; and the burner injection angle has a significant impact on the flow patterns and heat transfer. The study demonstrates that CFD can be a useful tool for analyzing the combustion flow of an industrial furnace.

Abstract:
Due to the growing production on a global scale, the use of fossil fuels is also increasing. Therefore, the control of pollutant emissions produced in the industrial sphere has become a global concern. In general, an imperfect combustion process has a negative impact on the overall efficiency and economy of plant operation, but at the same time increases the share of total emissions in the environment. We also encounter this problem when operating gas fired melting furnaces. Therefore, the paper aimed to describe the results of experimental measurements of the number of emissions produced during the operation of a gas fired melting furnace, which in practice is mainly used for melting alloys. Experimental measurements were oriented to find the most suitable variant of the operating mode of the gas fired melting furnace with regard to minimizing the total amount of emissions produced.

Abstract:
Three firing schemes for an industrial oxygen-fired glass melting furnace were examined to determine the thermal performance and relative merits of each scheme. A comprehensive computer model was used to investigate the effects of each scheme on the combustion and heat transfer in the furnace. The three-dimensional computer model, suitable for predicting and analyzing fluid flow, combustion and heat transfer has been used to simulate the combustion space of the furnace. The turbulent flow field is obtained by solving the Favre averaged Navier-Stokes equations and using the k-ε model to calculate the turbulent shear stresses and close the equation set. The combustion model consists of a single step, irreversible, infinitely fast reaction. A mixture fraction is used to track the mixing of fuel and oxidant and thus reaction progress in this mixing limited model. An assumed shape PDF method is utilized to account for turbulent fluctuations. Radiative heat transfer in the combustion gases and between surfaces is modeled using the discrete ordinates method coupled with the weighted-sum-of-gray-gases model. The model furnace for all three firing schemes was the same size and shape, was charged from the rear end wall and was pulled from the front wall. The three schemes investigated were: 1) non-interlaced side-wall fired, 2) interlaced side-wall fired, and 3) end fired. The results show that all three arrangements provide similar thermal performance and heat transfer characteristics. However, the flow field for the non-interlaced arrangement is very complex in the region where jets from opposing walls meet at the furnace center line. This type of jet interference can lead to unstable flow, particularly at the centerline of the furnace. Unstable flow conditions can affect the heat transfer characteristics of the furnace and make the furnace difficult to operate. Conversely, the interlaced and end-fired schemes do not exhibit the jet interference seen in the non-interlaced arrangement. While the results indicate that the thermal performance of all three arrangements were similar, the possibility of jet interference suggests that an interlaced or end-fired arrangement is preferable.

Abstract:
It is well known that high-level radioactive wastes (HLRAW) are usually vitrified inside electric furnaces. Disadvantages of electric furnaces are their low melting capacity and restrictions on charge preparation. Therefore, a new concept for a high efficiency combined aggregate – submerged combustion melter (SCM)–electric furnace was developed for vitrification of HLRAW. The main idea of this concept is to use the SCM as the primary high-capacity melting unit with direct melt drainage into an electric furnace. The SCM employs a single-stage method for vitrification of HLRAW. The method includes concentration (evaporation), calcination, and vitrification of HLRAW in a single-stage process inside a melting chamber of the SCM. Specific to the melting process is the use of a gas-air or gas-oxygen-air mixture with direct combustion inside a melt. Located inside the melt are high-temperature zones with increased reactivity of the gas phase, the existence of a developed interface surface, and intensive mixing, leading to intensification of the charge melting and vitrification process. The electric furnace clarifies molten glass, thus preparing the high-quality melt for subsequent melt pouring into containers for final storage.
