Underport firing allows a high degree of flame coverage of the melt using multiple burners mounted beneath the port sill, providing easy access for adjustment and maintenance. Providing the furnace aerodynamics are correct, underport firing gives both high thermal efficiency and high melt rates with a variety of liquid fuels. Using the burner block sealing system with internal low pressure air cooling, and with careful selection of burner system and port design, low levels of NOx are achievable. The Eclipse GT/CPA burner support bracket ensures accurate repeatable burner location, simple adjustment, and quick removal of burner, all of which are essential for an efficent underport burner system.
