What is the lowest specific energy consumption in China’s polysilicon industry at present, in KWh/kg? ? We are around 70-80. .
Does it refer to reduction or synthesis? The lowest energy consumption for reduction should be reduced to 40-50
The power consumption in the modified Siemens method is around 40 to 50; with better control, it can drop to 38, but this comes at the cost of the surface quality – these two aspects cannot be achieved simultaneously
It seems that there’s no point in integrating hydrogenation. . .
Not many people can reach 50 these days, :)
If the overall power consumption is good, it can reach over 60
The power consumption is 75 kWh/kg for 18 rods, 60 kWh/kg for 24 rods, and 50 kWh/kg for 36 rods. It’s already great to be able to maintain this level.
For the 8th floor, does this refer to the electricity consumption for reduction? It seems a bit too high; under current market conditions, it’s only possible to maintain a level of electricity consumption for reduction at around 50 kWh.
The reduction power consumption is closely related to the type of reduction furnace, as well as to the operating methods. With a good furnace type, this value can be reduced to around 40–50; with a poor furnace type, even with great efforts, it can only be reduced to around 70–80.
More realistic data. There are hardly any values below 50; of course, this refers to the average reduction electricity consumption – don’t use data from individual furnaces for this purpose.
Currently, the power consumption of large furnaces has seen a noticeable decrease
