The results contribute to process fault diagnosis, process optimisation, expansion of heuristic knowledge and to the verification of mathematic models. Consequently these results can make a contribution to increasing efficiency and reducing the costs for energy and raw materials. The methodical procedure will be briefly presented in the following text. Chapter 2 will describe the glass furnace in its entirety with its subunits and aggregates. Particular attention is placed on the aggregates that influence the transient and fluidic aspects of the glass melt. Chapter 3 will introduce residence time and residence time distribution as input and output descriptions with their statistical evaluation options. Furthermore, this theoretical part section will describe idealised fluidic models whose serial and parallel interaction give insight to process flows and the macro-mixing state. A general description of three dimensional glass furnace models serves as a theoretical basis for the comparison made in Chapter 4; a comparison of residence time distributions which are experimental and those which are calculated from three dimensional models. Chapter 4 explains the tracer method and the properties of tracer material which is necessary for this method. Residence time distribution will be correlated to distinct points which are subject to individual, transient and fluidic behaviour. Only with the help of a uniform evaluation for residence time distribution is it possible to improve the comparison of numerous experiments with one another and increase the significance of statistical distribution. This is also a foundation for advanced evaluation and verification of Residence Time Distribution (RTD) - and three dimensional simulation. After the methodology for tracer experiments and their evaluation potentials have been extensively explained, the next section will present concrete results. Four different glass melt tanks for hollow glass production were used as experimental objects (U-flame tank with filling end, U-flame tank with two filling ends, cross-fired tank at the end of a furnace campaign and the same cross-fired tank after cold repair). These results were compared with one another and critically discussed, as well as also compared and verified with RTD simulation and three dimensional simulation. Chapter 5 presents excerpts from the Procedure Book that was developed for industrial application. The individual processes and conditions necessary for meaningful execution of a tracer test are described in this chapter. The objective is to standardise, simplify, accelerate and economically perform processes. This book contains every type of information for rapid and independent execution of tracer experiments, from the procurement of tracer materials to the evaluation of residence time distributions.","abstract_html":"This work introduces an advanced development, experimental, process with which the transient behaviour of melt can be portrayed in a standardised and fault-free manner.
