Problems solved by technology

[0002] The existing magnesium smelting nozzle is that the air nozzle and the natural gas nozzle are respectively installed on the furnace body; the air nozzle is responsible for air intake and smoke exhaust. The heat body absorbs the heat of the heat storage body and enters the furnace. When exhausting, the flue gas is discharged from the heat storage body in the heat storage chamber of the air nozzle; Installation is responsible for injecting natural gas into the furnace; the contact between natural gas and preheated air is slow and uneven, resulting in ineffective combustion, high gas consumption, and large temperature deviation on the furnace surface

Abstract

The invention relates to a premixed natural gas combustion nozzle for magnesium smelting and reducing and heat storage, relating to a nozzle for a metal magnesium smelting furnace, and in particular relating to a nozzle for mixing of combustible gas and preheated air of a metal magnesium smelting furnace; the central position of a nozzle shell is provided with a central spray pipe; one end of the central spray pipe is connected with a natural gas intake pipe; the nozzle shell is coaxially and sequentially provided with an air box and a heat storage chamber internally; the other end of the central spray pipe is communicated with a premixed chamber; and the front end of the premixed chamber is connected with a mixed air nozzle. The nozzle provided by the invention has the beneficial effects that energy is saved, the natural gas consumption is reduced, the service life of a natural gas spray gun is prolonged, the temperature in the furnace is uniform, the production yield of each reduction tank is stable, and the production yield of each tank is improved effectively.

Description

Technical field: [0001] The premixed natural gas magnesium smelting reduction regenerative combustion nozzle is a nozzle used in a smelting furnace, in particular to a nozzle used for mixing combustible gas and preheated air in a metal magnesium smelting furnace. Background technique: [0002] The existing magnesium smelting nozzle is that the air nozzle and the natural gas nozzle are respectively installed on the furnace body; the air nozzle is responsible for air intake and smoke exhaust. The heat body absorbs the heat of the heat storage body and enters the furnace. When exhausting, the flue gas is discharged from the heat storage body in the heat storage chamber of the air nozzle; The installation is responsible for spraying natural gas into the furnace; the contact between natural gas and preheated air is slow and uneven, so it cannot be burned effectively, the gas consumption is high, and the temperature deviation of the furnace surface is large.
