Abstract
The invention relates to a connecting pipe set of a pulverized coal burner for a magnesium reduction furnace. The connecting pipe set comprises a large flange 1, a fire check sight glass 2, pipe bundles 3 and flanges 4. The connecting pipe set mainly has the advantages that the fire check sight glass is reasonably designed in the center of the pipe bundles, so that the burning state of flames is observed comprehensively and scientifically.
Description
Technical field
The present invention relates to a kind of adapter group 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 adapter group 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 adapter group that the present invention relates to a kind of coal burner of metal magnesium reduction furnace, comprise large flange 1, see fiery sight glass 2, tube bank 3, flange 4 forms, it is characterized in that the fiery sight glass 2 of seeing of the coal burner of described a kind of metal magnesium reduction furnace distributes the central authorities of tube bank 3.
advantage of the present invention is mainly reflected in:
To see that fiery specula reasonable design is at tube bank center, make to observe flame combustion state comprehensive, scientifical.
description of drawings 1 is a kind of coal burner of metal magnesium reduction furnaceadapter group
schematic diagram:
1-large flange 2-sees that fiery sight glass 3-restrains 4-flange.
detailed description of the invention illustrates embodiment 1:
tell about below in conjunction with Fig. 1a kind of adapter group of coal burner of metal magnesium reduction furnace
the course of work:
The present invention relates to a kind of adapter group of coal burner of metal magnesium reduction furnace, comprise large flange 1, see fiery sight glass 2, tube bank 3, flange 4 forms, it is characterized in that the fiery sight glass 2 of seeing of the coal burner of described a kind of metal magnesium reduction furnace distributes the central authorities of tube bank 3.To see that fiery specula reasonable design is at tube bank center, make to observe flame combustion state comprehensive, scientifical.
