Abstract
The invention relates to a fire observation speculum for a pulverized coal burner of a magnesium metal reduction furnace. The fire observation speculum comprises a flange 1, an eye lens 2, a sealing gasket 3, a steel tube I 4, a blind 5, a steel tube II 6, bolts 7 and nuts 8. The fire observation speculum disclosed by the invention has the main advantages that the flame distribution status in a hearth of the reduction furnace can be clearly observed by the structural design of the fire observation speculum.
Description
Technical field
What the present invention relates to a kind of coal burner of metal magnesium reduction furnace sees fiery specula.
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, there is provided a kind of can improve the coal burner of the air-coal separating combustion efficiency of breeze airflow better see fiery specula, thus suppress the generation of coal dust NOx better.For achieving the above object, the technical solution used in the present invention is
:what the present invention relates to a kind of coal burner of metal magnesium reduction furnace sees fiery specula, comprise flange 1, visual mirror 2, sealing gasket 3, steel pipe Ι 4, closure plate 5, steel pipe II 6, bolt 7, nut 8 form, what it is characterized in that the coal burner of described a kind of metal magnesium reduction furnace sees that the visual mirror 2 of fiery specula is arranged on flange 1 li, is fixed by bolt 7 and nut 8.Described sealing gasket 3 is arranged in the groove of flange 1, is connected to steel pipe Ι 4 simultaneously.Described steel pipe Ι 4 is sleeved in steel pipe II 6, and the two is fixedly connected with by closure plate 5.
advantage of the present invention is mainly reflected in:
Structural design clearly can observe the flame distribution situation in reduction furnace burner hearth.
