Research on Electricity Optimization of Reduction Furnace in Polysilicon Production
The production of polycrystalline silicon is a continuous production,and the electricity load is relatively stable.Under the peak-valley-flat electricity price mode,the electricity cost is higher.Taking a polysilicon production enterprise in Henan Province as an example,this paper combined the time-of-use electricity price policy of Henan Province in three periods of the year,analyzed the characteristics of the reduction furnace of the key power consumption process of polysilicon production,and established the power consumption optimization model of polysilicon reduction furnace to explore the power consumption mode of peak shaving and valley filling.According to the electricity optimization model,through the opti-mization of production organization,the operation time of the reduction furnace is adjusted.If the the re-duction furnace runs at 19:00 every day,the electricity cost of each operation cycle can be reduced by a-bout 12 000 yuan,which can reduce the electricity cost of the reduction furnace by about 4%,and the cost reduction effect is obvious.
