Taking the customer’s selection of a 400-kW induction heating furnace (heating temperature: 1,200℃) as an example: For parallel-connected equipment, the power consumption is calculated based on the highest efficiency at 400 kWh/ton; for series-connected equipment, the power consumption is 360 kWh/ton. The actual difference in power consumption between the two types of equipment is 40 kWh/ton. Assuming one unit operates 8 hours per day and the month is calculated as 28 days, the daily power savings amount to 40 kWh/h × 8 hours = 320 kWh. At an electricity price of 1 yuan per kWh, the annual cost savings would be: 320 kWh × 28 days × 12 months × 1 yuan/kWh = 107,520 yuan! This means the company can save approximately 100,000 yuan each year!
