Several issues in polysilicon reduction
Thread Content
I have a few questions for fellow sailors: 1. What is the maximum exhaust volume per hour for the rod furnace in the restoration process 12? 2. What is the typical pressure in the reduction furnaces at your companies, in kilograms? What’s the ratio?
The maximum gas flow rate can reach 600 Nm3/h, though this is not absolute and requires calculation. Reduction furnaces come in two types: atmospheric pressure and pressurized; generally, furnaces under pressurized conditions have a shorter processing time compared to those at atmospheric pressure.

The amount of exhaust gas is determined by the feeding schedule you use as well as process conditions such as temperature； The pressure can be adjusted according to one’s own production conditions
At normal pressure or high pressure, it depends on the method used; it depends on whether the company prioritizes volume or quality. In any case, these parameters can be adjusted
2# zhangrang 600NM/3 per furnace?
Single furnace, 600, pressure 0.8 KG
For a single furnace, the amount is around 400; the pressure is 0.8 kg. The typical ratio is 1:7, though it can sometimes be 1:6 – it depends on what you prioritize: better product quality or higher production volume
So, what’s the air intake volume in your area roughly? 8# wyc6880
Like the domestic reduction furnaces produced by Kaiyuan Chemical, these furnaces operate at a pressure of 3 kilograms, and the reaction ratios change depending on the production cycle.
0.8Mpa is pressurized, right?
