The invention relates to a submerged combustion burner (1) and to a inciter comprising submerged combustion burners (1). The burner comprises at least one oxidant feeding tube, at least one fuel feeding tube, a burner head having a peripheral envelope, the fuel and oxidant feeding tubes abutting against the burner head, at least two, preferably at least three, peripheral outward directed nozzles, each of the nozzles having a nozzle outlet, the nozzle outlets being arranged on a peripheral line on the peripheral envelope of the burner head, the nozzle outlet axis being inclined by an angle of 5 to 30° to the horizontal, and the nozzles practiced in the burner head being connected to the oxidant feeding tube and to the fuel feeding tube.

A method of processing a glass material includes guiding and/or focusing light from a light source to glass material in a hot stage of a processing system, where the light source provides light at a wavelength λ that interacts with crystals that may be formed in the glass material. The method includes collecting and/or guiding light directed from the glass material in the hot stage to a wavelength separator, and separating the light directed from the glass material to provide a spectrum δ having wavelengths that are within about twenty nanometers of the wavelength λ. The method includes observing with a detector light of the spectrum δ to identify nano-scale shifts in the wavelength λ caused by interaction with crystals, if present, within the glass material in the hot stage of the processing system.

In a thermochemical regenerator wherein gaseous combustion products that are formed by combustion in a furnace are passed from the furnace into and through a first regenerator, the combustion products are combined with gaseous fuel, and the resulting mixture is passed into and through a second regenerator wherein the mixture undergoes an endothermic reaction to form syngas, the thermochemical regeneration is enhanced by injecting fuel gas into a recycle stream comprising the combustion products from the first regenerator to entrain recycled flue gas that passes out of the first regenerator and to impel the mixture into the other regenerator.

A batch feeding apparatus, a submerged combustion melter, and method are disclosed. The batch feeding apparatus can include a batch feeding apparatus comprising a detachable feeder alcove for providing batch material to a melter, the feeder alcove including at least one side wall and a cover; and a batch feeder sealingly coupled to the cover, that feeds the batch material to the feeder alcove. The batch feeding apparatus may include an extendable panel that extends downwardly below a batch inlet of the feeder alcove to molten glass, and is configured to maintain contact with the molten glass to seal off a feeder alcove interior. Additionally, the batch feeding apparatus may include a heating device, a cleaning device, and/or a storage device.

A furnace, and a method of firing it, wherein part of the fuel supplied to the furnace is produced from waste plastics by a depolymerisation process, waste heat from the furnace being used to promote the depolymerisation process. The furnace is equipped with regenerators for waste heat recovery and is fired alternately in first and second opposed directions, with the direction of firing periodically reversing between the first direction and the second direction.
