Abstract
The invention relates to a housing for pulverized coal burners of magnesium reduction furnaces, which consists of a flange (1), a connecting pipe I (2) and a connecting pipe II (3). The main advantage of the housing is that the adoption of high-abrasion-resistance manganese steel plates can prolong the service life of a burner.
Description
Technical field
The present invention relates to a kind of housing of coal burner of metal magnesium reduction furnace.
Background technology
In prior art by Pulverized Coal Concentration device, utilize the effect of coal dust inertial separation to realize the air-coal separating of breeze airflow, in coal burner, form thick coal culm air-flow and thin powdered coal air-flow.But before penetrating after coal burner outlet, entering burning-out zone, do not separated completely between thin powdered coal air-flow and thick coal culm air-flow, thin powdered coal air-flow and thick coal culm air-flow are easy to again mix, and destroy air-coal separating effect, and then limited to NOx inhibitory action.How to realize the air-coal separating of breeze airflow better, thus the generation suppressing reduction furnace NOx is better the technical barrier that current those skilled in the art face.
summary of the invention:
The object of the invention is to for above-mentioned technical barrier, first object of the present invention is, provides a kind of housing that can improve the coal burner of the air-coal separating combustion efficiency of breeze airflow better, thus suppresses the generation of coal dust NOx better.For achieving the above object, the technical solution used in the present invention is: the housing that the present invention relates to a kind of coal burner of metal magnesium reduction furnace, comprise flange 1, tube connector Ι 2, tube connector II 3 composition, the flange 1 of the housing of the coal burner of described a kind of metal magnesium reduction furnace, tube connector Ι 2, company are high abrasion manganese steel.Described flange 1 is welded to connect with tube connector Ι 2.Described tube connector II 3 is welded to connect with tube connector Ι 2 square crossing.
advantage of the present invention is mainly reflected in:
Adopt high abrasion material manganese steel plate can service life of prolonging combustion device.
description of drawings 1 is a kind of schematic diagram of housing of coal burner of metal magnesium reduction furnace:
1-flange 2-tube connector Ι 3-tube connector II.
detailed description of the invention illustrates embodiment 1:
tell about below in conjunction with Fig. 1a kind of coal burner of metal magnesium reduction furnace
the course of work of housing:
The present invention relates to a kind of housing of coal burner of metal magnesium reduction furnace, comprise flange 1, tube connector Ι 2, tube connector II 3 composition, the flange 1 of the housing of the coal burner of described a kind of metal magnesium reduction furnace, tube connector Ι 2, company are high abrasion manganese steel.Described flange 1 is welded to connect with tube connector Ι 2.Described tube connector II 3 is welded to connect with tube connector Ι 2 square crossing.
Claims (3)
1. the present invention relates to a kind of housing of coal burner of metal magnesium reduction furnace, comprise flange 1, tube connector Ι 2, tube connector II 3 composition, it is characterized in that the flange 1 of the housing of the coal burner of described a kind of metal magnesium reduction furnace, tube connector Ι 2, connecting is high abrasion manganese steel.
2. the housing of the coal burner of a kind of metal magnesium reduction furnace according to claim 1, is characterized in that described flange 1 is welded to connect with tube connector Ι 2.
3. the housing of the coal burner of a kind of metal magnesium reduction furnace according to claim 1, is characterized in that described tube connector II 3 is welded to connect with tube connector Ι 2 square crossing.
