Abstract
The utility model discloses a premixing natural gas magnesium smelting reduction heat-accumulating burner nozzle, which relates to a nozzle for a metal magnesium smelting furnace, in particular to a nozzle for mixing combustible gas with preheated air in a metal magnesium smelting furnace. A central spray pipe is arranged at the central position of a nozzle shell; one end of the central spray pipe is connected with a natural gas inlet pipe; an air box and a heat-accumulating chamber are coaxially sleeved in sequence in the nozzle shell; the other end of the central spray pipe is communicated with a premixing chamber; and the front end of the premixing chamber is connected with a mixed gas nozzle. The premixing natural gas magnesium smelting reduction heat-accumulating burner nozzle has the beneficial effects that: energy is saved, natural gas consumption is lowered, the service life of a natural gas spray gun is prolonged, the temperature in the furnace is uniform, the yield of each reduction tank is stable, and the single tank yield is effectively increased.
Description
Technical field:
Premixed natural gas magnesium smelting reducing heat-accumulation combustion nozzle is a kind of smelting furnace nozzle, particularly is used for the nozzle that smelting-furnace for magnesium metal fuel gas and preheated air mix.
Background technology:
Existing refining magnesium nozzle is that air nozzle and natural gas nozzle are to be installed in respectively on the body of heater; Air nozzle is born air inlet and smoke evacuation, during air inlet, the accumulation of heat chamber of air nozzle is only born the air that enters and is entered in the stove after by the heat storage placed in the chamber and the heat that absorbs heat storage, and during exhaust, flue gas is discharged by the heat absorption of the heat storage in the accumulation of heat chamber of air nozzle back; Natural gas nozzle and air nozzle are independent separately, install in one side of air nozzle, are responsible for natural gas is sprayed in the stove; Natural gas contacts slow incomplete mixing with preheated air, can not active combustion, and the gas consumption height, the furnace surface temperature deviation is big.
Summary of the invention:
The premixed natural gas magnesium smelting reducing of the utility model heat-accumulation combustion nozzle goal of the invention is: design invention a kind of with prior art structure different effective premix air and natural gas fully, reduce gas consumption, improve the natural gas nozzle service life, realize the interior uniform premixed reduction heat-accumulation combustion nozzle of temperature of stove.
The invention of the premixed natural gas magnesium smelting reducing of the utility model heat-accumulation combustion nozzle is achieved in that by regenerator, bellows, core jet pipe, gaseous mixture nozzle, premixer, smelting furnace furnace wall, natural gas air inlet pipe and nozzle body to be formed; Nozzle body center mounting center jet pipe, core jet pipe one end connect the natural gas air inlet pipe, and in nozzle body concentric suit bellows and regenerator successively, the core jet pipe other end communicates with the premixer, premixer's front end connection gaseous mixture nozzle; The premixer is a platform shape body, holds concentric to connect regenerator greatly, and small end connects the gaseous mixture nozzle, is made up of corundum or heat-resisting steel part; Regenerator is made up of refractory brick, cellular heat storage.
A kind of smelting-furnace for magnesium metal nozzle, regenerator is made up of refractory brick, cellular heat storage, accumulation of heat during smoke evacuation, air passes heat storage, with heat absorption, core jet pipe be sleeved on heat storage middle part fuel gas by the time be able to Fast Heating, after the premixer makes natural gas and preheated air mixes, enter the burner hearth internal combustion then.
This premixed natural gas magnesium smelting reducing heat-accumulation combustion nozzle beneficial effect of the invention: the effective premix of natural gas and air, reduce gas consumption, improve nozzle service life, temperature is even in the stove, and a reduction jar stable yield effectively improves single jar of output.
