This project is for 12 Ton Induction Furnace Dust Removal System. The project is contracted and executed by Shanghai Prime Metallurgy Technology Co., Ltd.
The original flue gas is around 1100-1400℃ while after cold air dilution, the flue gas at the inlet of dust collector is less than 120℃.
The inlet of dust collector is provided with a temperature control device and cold air dilution valve.
For 12 ton induction furnace, discharge amount is around 40,000-50,000 Nm³/h, flue gas temperature is ≤120℃ and normally around 60-80℃ (assume flow under working conditions is 48,000-60,000 m³/h)
Induced draft fan adopts variable frequency motor for transmission, so as to save energy consumption.
During melting, the fan operates at a low frequency (around 35 Hz) with an air volume of 40,000 m³/h; during tapping, the fan operates at a high frequency (around 45 Hz) with an air volume of 60,000 m³/h.
Once the dust removal system is completed, the flue gas generated by furnaces can be properly handled, recovering around 200ton dust per year. Dust concentration at working position will be lower than 10 mg/Nm³, reaching relevant labor hygiene standards; and flue gas capture efficiency will be over 95% and flue gas emission concentration will be no more than 50 mg/Nm³, meeting national and local environmental conservation standards and gain excellent social and environmental benefits.
Our complete quality management system, the process control covering from Scheme formulation, engineering technology, and detailed design, to processing and manufacturing of equipment and material, ex-factory test and site erection and commissioning till it is put into production, which through multi-level inspection, tour inspection, supervision, and node control can ensure quality of the final product.
The executive team is abundant in experience of overseas project implementation with similar project working experiences, esp. experience in Southeast Asia, and Middle East projects.
