One or more embodiments of a burner panel for a metallurgical furnace is described herein. The burner panel has a body having a top surface, a bottom surface, a left surface, a right surface, and a front surface surrounding an interior burner area. A spray-cool system disposed in the interior area. A burner tube at least partially disposed in the interior burner area and extends into the front surface. The burner tube is configured to accept a burner.

A multi-tube burner system for efficient mixing of fuel and air for combustion is disclosed. The multi-tube burner system includes an air supply plenum, a multi-tube burner, and a combustor. Further, the multi-tube burner includes a set of tubes including the air supply section to receive combustion air and supply the received combustion air to a mixing section. Furthermore, the multi-tube burner includes a set of fuel pipes to receive fuel from a set of fuel inlets and supply the received fuel to a set of fuel plenums. Furthermore, a pair of fuel receiving channels receive the fuel from the set of fuel plenums and a fuel injector pin injects the received fuel from the pair of fuel receiving channels to the mixing section. Further, a set of mixing holes allow egression of the combustion air and the fuel mixture from the mixing section to the combustor.

The invention relates to the field of power engineering and can be used in heating systems, more particularly in water heaters or boilers, in disposal systems fueled by the combustion of associated gas, and in electrical energy generating systems. A pulse combustion apparatus comprises a combustion chamber 14, at least one resonant channel 28 connected to the combustion chamber 14, a device 15 for removing heat which is linked to the combustion chamber and to the resonant channel and which consists of at least one chamber and/or at least one tube for a heat-exchanging agent 16. A device for supplying air and combustible gas, which is connected to the combustion chamber 14, comprises at least one gaseous medium nonreturn valve 17 and at least one guard chamber 18 of said valve 17. The at least one gaseous medium nonreturn valve 17 is directly or indirectly linked to the device 15 for removing heat via a vibration isolator 19, 24.

A combustion burner employed in a submerged combustion vessel used to melt high index glass includes an arch positioned on a burner in the submerged combustion vessel. An amount of combustible gas flows through a first port disposed in a first haunch of the arch and through a second port disposed in a second haunch of the arch. Fuel is supplied through an end port in a fuel supply line. The end port is disposed under the arch. An amount of glass is fed into the submerged combustion vessel and is melted inside the submerged combustion vessel by igniting the burner. Some of the melted glass at least partially solidifies against a wall of the submerged combustion vessel such that the melted glass is contained in a vessel of itself.
