Method and burner of hydrogen combustion in industrial furnace, especially in a glass furnace or a furnace for metal melting, by means of a multi nozzle burner

A method of hydrogen gas combustion in an industrial furnace, especially in a glass furnace or a furnace for metal melting, by means of a multi nozzle burner with controllable flow of a hydrogen fuel gas composition and an additional gas composition through a cavity to the industrial furnace to form a reacting mixture of the hydrogen fuel gas composition and the additional gas composition for combustion in the industrial furnace, wherein:

• the hydrogen fuel gas composition is introduced into the cavity from the multi nozzle burner by a central flow of gas from a tip of at least one central gas nozzle with a simultaneous input of at least one independent further flow of the additional gas composition from a tip of at least one concentric gas nozzle, wherein
• the central flow of gas of the hydrogen fuel gas composition is surrounded by a concentric flow of gas of at least the additional gas composition, wherein the concentric flow of the additional gas composition is a peripheral concentric flow of gas, wherein
• the tip of the at least one central gas nozzle, the tip of the at least one concentric gas nozzle and optionally a tip of a further concentric gas nozzle are arranged flush to the cavity or inserted in the cavity at a same insertion distance,
• the hydrogen fuel gas composition is formed by a first fuel gas constituent of 80 weight % or more of hydrogen gas and 20 weight % or less of another fuel gas or gas constituent than hydrogen gas, and
• the additional gas composition is formed by a first oxidant gas constituent containing oxygen with an oxygen content of 80 weight % or more of oxygen gas, and
• a1) the central flow of gas momentum per second of the hydrogen fuel gas composition exiting the tip of the at least one central gas nozzle is in the range 0.001-1.2 [kg m/s2],
• b1) the concentric flow of gas momentum per second of the additional gas composition exiting the tip of the at least one concentric gas nozzle is in the range 0.01-10.4 [kg m/s2],
• c) a ratio of a heating burner power (WCHEM [W]) to a hydrogen fuel gas composition kinetic power (WKIN [W]) is in the range WRATIO=100,000-4,000,000.
