Optimization Potentials for Steel Production from the Application of Oxygen Combustion
Michael Potesser¹ ; Johannes Rauch¹ ; Davor Spoljaric¹ ; ¹Messer Group GmbH, Gumpoldskirchen, Austria;
Paper Id: 118 [Abstract]

Oxygen combustion technologies are lowering the production costs of many processes, since energy costs are continuously raising. Oxygen is used more and more in combustion systems technologies, like oxygen burners, oxygen lancing, or oxygen enrichment, in order to increase the capacity or conserve energy in particular furnaces, Oxyfuel is used to provide discrete oxygen rich areas in a furnace to allow complete combustion separately from a reducing zone or lower the emission volumes. This article analyzes the possibilities and the advantages of oxygen application in different furnaces used for steel production, based on Messer results and literature review.

Application and Results of Oxipyr®-diluted Combustion in Aluminum Furnaces
Michael Potesser¹ ; Johannes Rauch¹ ; ¹Messer Group GmbH, Gumpoldskirchen, Austria;
Paper Id: 117 [Abstract]

Diluted, mild, or flameless oxyfuel combustion has shown huge successes in past years as an optimization tool for different high temperature applications. This innovative combustion technology has a lower flame temperature, more uniform temperature distribution, and low concentrations of oxygen as well as nitrogen inside the furnace, leading to low fuel consumption and very low NOx levels. In this work, we analyze the optimization processes of different types of rotary and reverberatory furnaces (fix, tiltable) with Messer Oxipyr® burners, which led to impressive savings, dross reduction, and ecological improvements for the customers. A review of the available literature on this topic is also given.
