Praxair Converts O-I Furnace

O-I has converted a conventional air-fuel glass furnace to oxy-fuel using Praxair's combustion technology. Praxair will supply gaseous oxygen to the 180/tpd, non-cryogenic glass plant located in Oklahoma, USA. Oxy-fuel combustion uses oxygen rather than air to enhance combustion, improve energy efficiency in the glass melting process and reduce nitrogen oxide emissions. In addition to supplying the oxygen, Praxair has provided the oxy-fuel combustion flow control skids and installed its dilute oxygen combustion Wide Flame Burner technology, designed to minimise furnace emissions and reduce furnace crown deterioration.
