VitroGLO-SPTC

Low NOx Gas Burner

The VitroGLO-UPTC is a NEW generation of Low NOx gas burners for application to a Regenerative Glass Melting Furnace.  Based on the Global Combustion VitroGLO-SP Gas burner and installing on the same sideport bracket, these burners are designed to operate at a low gas supply pressures, and provide a highly luminous adjustable flame within the melting furnace.  A key feature of the VitroGLO-SPTC Gas Burner is that the flame length is adjustable (by up to 30%) by means of proportioning the velocities of two concentric gas jets in the visible flame, thus optimising the flame length within the furnace with ease and without the need to change the gas nozzles.  On the VitroGLO-SPTC gas burner, this is controlled by adjusting the proportion of the individual gas supplies, and by adjustment of the impulse nozzle position in relation to the main nozzle.

In Sideport firing applications, a high degree of flame coverage can be achieved, which with the high luminosity generated by the VitroGLO-SP Gas Burner, maximises the heat transfer to the glass, and minimises NOx emissions.  The sideport 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 burner against the the burner block seal ring/plate/insert.  For Sideport applications, Global Combustion can provide both water cooled or air cooled block sealing systems.

The support bracket provides 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-SPTC Gas burner.

Global Combustion can supply the VitroGLO-SPTC gas burner for retrofitting to an existing burner installation.

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