Throughport Gas Burner

These water cooled burners are designed to be inserted into the port neck of a regenerative glass furnace. The burners are fitted to the Global Combustion Systems retraction mechanism, which is used to withdraw the burner from the port when not firing. The use of throughport burners with the retraction mechanism provides stable reproducible combustion conditions, essential for high glass quality.

These burners are fitted with a single conical flame nozzles. This flame configuration allows for one, two or three burners to be installed on each port. This burner is interchangeable with Global Combustion’s Throughport Oil Burner (VitroOIL-TP).

The retraction mechanism operates pneumatically, and is designed for a long low maintenance life and ensures perfect alignment without the need for adjustment during operation. Vertical angle, horizontal and vertical position adjustments are
incorporated into the mechanism. single mechanism can carry up to three burners per port.

Global Combustion Systems can also provide auxiliary equipment including a complete natural control system, with full supervision and commissioning services.
