High Temperature Membrane Module for Oxygen Enrichment of Combustion Air

The flame temperature in reheat furnace can be raised by enriching the combustion air with oxygen. Thermal processing equipment which previously had to rely on high-quality fossil fuels can now be operated with previously unusable process gases and biogases. This benefit arises by oxygen enrichment. To produce O2 at low cost, a new method involving ceramic membranes was developed in a collaborative project. Following this, investigations were conducted on the lab-scale furnace to determine whether the combination of high-calorific gas and air could be replaced by a combination of low calorific gas and oxygen for use in reheating furnaces. It was demonstrated that the necessary furnace chamber temperature can also be achieved with low-calorific gases.
