Abstract
A ceramic burner for a hot blast stove has a central gas duct that opens into the central zone of a burner crown and side air ducts on both sides of the gas duct which also open into the central zone. To improve combustion characteristics, there is a central air duct in the gas duct opening out within it. Air is supplied to the central air duct in an upward flow which exits in two opposing directions through side openings.
