Stara Glass: CFD modelling of regenerative glass furnace port-necks and their new role of post-combustors

The introduction of a strict regulation about NOx emission in the European glass industry has driven furnace operators towards the use of more reduced combustion tunings that, as a matter of fact, have changed the role of regenerative furnaces ports from mere ducts to actual chemical reactors where the CO to CO2 oxidation finds its complexion. This article explores the ongoing process of optimization of the design of this part and focuses on the current results we have reached, along with the further efforts we are making towards a reliable CFD modelling of regenerative glass furnace combustion, under stateof-the-art air/fuel ratio conditions.
