Abstract: A method for providing automatic enhanced staged oxygen combustion in a glass furnace including providing two or more burner assemblies each positioned to provide a flame in the glass furnace. Each of the burner assemblies includes a burner body having a primary gas inlet in fluid communication with a gas source through a primary gas valve, and a staged injector sub-assembly having a secondary gas inlet in fluid communication with the gas source through a secondary gas valve. The primary gas valve and the secondary gas valve are automatically controlled to alternate the total gas flow between a first total gas flow condition with the secondary gas flow rate at a secondary gas flow rate maximum value and a second total gas flow condition with the secondary gas flow rate at a secondary gas flow rate minimum value to provide enhanced staged oxygen combustion.

Abstract: A block and burner assembly including a flat flame burner sub-assembly which includes a flat flame burner body in fluid communication with a gas source. The flat flame burner body includes a gas inlet in fluid communication with the gas source and a gas nozzle, and a fuel inlet in fluid communication a fuel nozzle, wherein the gas nozzle is arranged to at least partially encompass the fuel nozzle. The block and burner assembly includes a flat flame burner block arranged to receive at least a portion of the fuel nozzle and at least a portion of the gas nozzle, a staged injector sub-assembly in fluid communication with the gas source, and a staged injector block connected to the flat flame burner block and arranged to receive the at least a portion of the staged injector sub-assembly wherein the flat flame burner block and the staged injector block are separable.

Abstract: The present invention is related to a process for preparing safinamide and salts thereof, preferably safinamide methanesulfonate, with high yields and high enantiomeric and chemical purity without the need of using highly pure intermediates. The process of the present invention is suitable for the production of safinamide and its salts, preferably safinamide methanesulfonate, at industrial scale.
