Application and results of oxipyr® diluted combustion in aluminum furnaces

Abstract

Diluted, mild or flameless oxyfuel combustion has shown in the past years huge successes 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.
