VitroGLO-UPOG

Duel Fuel Underport Burner

VitroGLO-UPOG is a combination of the Global Combustion Low NOx gas  and oil burners for application to a Glass Melting Furnace.  They are designed to operate with a high efficiency low NOx VGA oil atomizer and low gas pressures, and provide a highly luminous flame.  It is is suitable for all gases and grades of fuel oil.  A Purge valve or Extractor valve is used with this burner to remove oil from the nozzle after firing

In Underport firing applications, a high degree of flame coverage can be achieved, which with the high luminosity generated by the VitroGLO-UPOG Dual Burner, maximises the heat transfer to the glass, and minimises NOx emissions.  The underport system incorporates a burner sealing system, which eliminates tertiary air and  provides burner cooling to increase the nozzle operational life. The burner support bracket both supports and fixes the seal ring in place against the burner block.  For underport applications, Global Combustion can provide both water cooled or air cooled block sealing systems.

Global Combustion provide two types of burner support bracket, depending on whether the bracket is to be supported from above or below the burner block.  Support from above has the advantage of allowing clear access to the flux line.  Both bracket designs provide simple vertical angle adjustment with an easily visible reference scale, allowing the flame position to be optimised withing the furnace.  The mechanism provides accurate burner location, and allows for quick and safe removal of the VitroGLO-UPOG Dual burner.

Global Combustion can supply the VitroGLO-UPOG Dual burner for retrofitting to an existing burner installation.  The VitroGLO-UPOG dual burner is interchangeable with other Global Combustion’s underport burner systems.

Global Combustion Systems can also provide auxiliary control equipment, including the fuel gas control system, and full supervision and commissioning services.
