As optimal technical scheme, above-mentioned heat exchanger tube includes the inner and outer tubes being mutually arranged, and said inner tube tube chamber constitutes institute
Exhaust passage is stated, is fed intake in channel described in the tube chamber composition between said inner tube and the outer tube.Using the above design, advantage
When being that high-temp waste gas is discharged through inner tube, the raw material to feed intake in channel is heated.
As optimal technical scheme, above-mentioned heat exchanger tube includes the inner and outer tubes being mutually arranged, and said inner tube tube chamber constitutes institute
The channel that feeds intake is stated, the tube chamber between said inner tube and the outer tube constitutes the exhaust passage.Using the above design, advantage exists
When high-temp waste gas is discharged through exhaust passage, the raw material in inner tube is heated.
As optimal technical scheme, described in above-mentioned heat exchanger tube feeds intake channel and exhaust passage is mutually juxtaposed.Use with
Upper design the advantage is that feed intake channel and the exhaust passage of parallel arranged pass through tube wall between the two and carry out heat exchange.
Heating electrode is equipped with as optimal technical scheme, in above-mentioned furnace body, which is connected with power supply circuit.It adopts
With the above design, it is convenient to smelting reduction process heat supply in stove to the advantage is that.
Advantageous effect：Using the utility model has the beneficial effects that in heat exchanger tube, high-temp waste gas flows direction and raw material
The direction of motion is dried raw material and preheats on the contrary, high-temp waste gas transfers heat to raw material by tube wall, on the whole
The heat utilization ratio for improving fusion reducing furnace, plays energy-conserving action.
