The article describes a numerical methodology for modeling the complete firing process in an industrial furnace. A three-dimensional model based on the finite volume method is presented and applied to the process. The homogeneity assumption "porous medium" is used to simplify the size of the computational domain and the reguired computational time. The effective properties of the porous model body are calculated and transferred to the simulated structures. The temperature profile in the furnace and the temperature distribution in the stacks can be calculated with the use of this model in an acceptable time. The numerical results are compared with experimentally measured values. A good agreement is found. Source


The rotary tube furnace combines, in most cases, the expectations of today of a modern continuous heat treatment furnace - high throughput, energy efficiency, easy automation and a reliable reproducibility. Today a number of applications can be realized by the use of high performance materials for the rotary tube. The various operational possibilities of rotary tube furnaces were recently extended by applications for the production of rare earth minerals and high purity quartz sand. Source

Since approx. 50 years microwave heating has been available for industrial use. For showing the advantages of this technique, the theory of microwave heating will be explained and the practical application will be demonstrated with some selected examples. The recent article gives an overview of the possible kinds of industrial microwave heating and the advantages of it against conventional heating. Source

In the following article, various types of furnaces for heat treatment of materials under inert gas and vacuum will be described. An introduction to the theory of inert gas/vacuum treatments is given. Different types of furnaces are described in their principal structure and in their most important applications. Necessary safety devices for the working with combustible and explosive gases are also mentioned. Source
