Abstract

Heat exchangers are used in gas burners as recuperators. Their efficiency is proportional to their surface which is usually limited by the burner length and diameter. Ceramic recuperators used nowadays in industrial burners are tubular. We studied and developed a new generation of ceramic heat exchanger with the final goal of increasing the efficiency or, at similar efficiencies, of reducing their size and weight. A commercial SiSiC heat exchanger component was used to guarantee safety and robustness. The use of structured textile geometries followed by their conversion into a ceramic is the main innovation of this work. [ABSTRACT FROM AUTHOR]

Abstract

The termal insulation of high temperature equipment may be subjected to many kinds of damages, leading to a degradation of its thermal properties. The aim of the present work was to check and predict damages that may occur during the operation of thermal equipment. This paper describes simulations and experiments that were performed in order to reproduce damages and to predict the degradation of the termal insulation by measuring temperature deviations at the outer wall of the equipment.

Abstract

The effort to develop a new type of industrial furnace can be reduced by the use of numerical simulation tools. This article describes numerical studies of the flow and temperature distributions in an aluminium melting furnace. The aim of the studies is the increase of efficiency of furnace operation by shortening the time span for melting the inserted material. After validating the numerical model, the influence of the level of liquid aluminium on the temperature of the flue gas was studied. Further simulations were carried out to check the influence of a rotation of the burner on the temperature distribution on the melting bridge. [ABSTRACT FROM AUTHOR]
