A burner holder for a burner lance in a glass melting plant. To easily and quickly change the burner lance angle to influence the process conditions in the glass melting plant, the burner holder has a retaining unit for securing the burner lance and a sealing plate with a passage. The sealing plate is configured to secure to the glass melting plant and is provided with a recess for receiving a burner lance head. The recess forms at least one part of a passage through the sealing plate. The retaining unit is connected to the sealing plate via at least one first pivot bearing, such that the retaining unit can be pivoted or swiveled about a first axis of rotation. The pivot bearing is attached or embedded directly on the sealing plate or is connected to the sealing plate via a support arm arranged on the sealing plate.

Refractory tile for protecting a wall of energy recovery tubes. A hot face of the tile is to be exposed to the interior of the furnace. A cold face, opposite the hot face, defines: a groove extending over the entire length of the tile and to receive one the tubes, and a fastening receptacle configured to receive a retaining member to immobilize the tile with respect to the tube. The tile has, in a transverse section plane, at least at each position between the position of the groove and the position of the fastening receptacle, a non-zero material thickness. The thickness is measured between the transverse profile of the hot face and a straight segment, which is referred to as the base and links the ends of the transverse profile of the hot face. The positions are determined along the base.

The present disclosure is directed to a firebox basket for a barbeque grill or smoker. In one form, the present disclosure provides a grill comprising an ash depository, a firebox basket positioned in the grill above the ash depository; and a cooking rack positioned above the firebox basket. The firebox basket comprises: a support basket defining an internal area, the support basket comprising: a plurality of concentrically stacked rungs that define a side wall of the firebox basket; and a grate positioned at a bottom of the plurality of concentrically stacked rungs; and a plurality of ceramic pieces disposed within the support basket. The support basket is configured to support the plurality of ceramic pieces around the internal area of the support basket.

A burner for a facility for melting vitrifiable materials, includes an injector block including a combustion gas distribution network and at least one injector, and a plate in glass and/or flame contact which overlaps the injector block and includes at least one injection hole in fluid communication with the injector, wherein the plate is removably attached to the injector block.

The present disclosure provides a plate-shaped heat insulator less susceptible to damage caused by thermal shrinkage. Provided is a plate-shaped heat insulator including an aggregate of multiple heat insulating members containing inorganic fibers, wherein the plate-shaped heat insulator is intended to be disposed in a combustion chamber.

According to the present disclosure, a flat-flame nozzle is provided for producing a flat flame in a flame chamber included in a burner assembly. The flat-flame nozzle is configured to conduct fuel from a fuel supply to an ignition zone in the flame chamber. In some illustrative embodiments, the flat-flame nozzle is also configured to conduct oxygen from an oxygen supply to the ignition zone to produce a combustible oxygen-fuel mixture in the flame chamber. In illustrative embodiments, a removable first plate-separation border frame is positioned to lie between a first lower plate and a companion first upper plate. This border frame is configured to cooperate with those plates to form in the flat-flame nozzle a fuel-discharge outlet and a fuel-transport passageway communicating with the fuel-discharge outlet.
