Low NOx Gas Burner
The VitroGLO-UP is a Low NOx gas burners for application to a Regenerative Glass Melting Furnace. 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-UP 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-UP gas burner, this is controlled by adjusting a calibrated adjustment sleeve at the back of the burner.
In Underport firing applications, a high degree of flame coverage can be achieved, which with the high luminosity generated by the VitroGLO-UP Gas 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-UP Gas burner.
Global Combustion can supply the VitroGLO-UP gas burner for retrofitting to an existing burner installation. The VitroGLO-UP gas burner is interchangeable with the Global Combustions VitroOIL-UP Fuel Oil Burner.
Global Combustion Systems can also provide auxiliary control equipment, including the fuel gas control system, and full supervision and commissioning services.
Product category: Combustion technology for oil and gas fired melting furnaces
Low NOx Oil Burner VitroOIL-UP is an Underport Oil burner for application to a Glass Melting Furnace. It is designed to operate with a high efficiency low NOx oil atomiser, and provide a highly luminous flame which is suitable for all grades of fuel oil. A Purge valve or Extractor valve is used with this burner to remove oil from the nozzle after firing.
The nozzle is designed to be easily assembled and disassembled for maintenance, and cannot be incorrectly assembled. The design of the atomiser is such as that parts in contact with oil remain cool to minimise maintenance and ensure reproducible performance Atomisation can be with air, steam or gas. In Underport firing applications, a high degree of flame coverage can be achieved, which with the high luminosity maximises the heat transfer rate to the glass and minimises NOx.
The underport system incorporates a burner sealing system, which eliminates tertiary air to reduce NOx and save fuel. The bracket holds the seal ring in place in the burner block and incorporates a cooling air supply ring for high efficiency cooling to increase operational life. The system incorporates a sealed burner system, which contributes to reducing NOx and fuel savings by eliminating tertiary air.
Two types of support bracket can be provided depending on whether the bracket is supported from above or below. Support from above has the advantage of allowing clear access to the flux line. Both provide simple vertical angle adjustment with a reference scale. The mechanism provides accurate burner location, and allows for quick and safe burner removal. The underport burner can be supplied without the burner bracket for retrofitting to existing burner installations. The oil burner is interchangeable with the Global Combustion Gas Burner.
Global Combustion Systems can also provide auxiliary equipment including a full Gas control system, with full supervision and commissioning services.
