Waste Energy Recovery from a Silicon Smelting Furnace — Technology Design and Economic Analysis

Abstract:

In order to improve the overall efficiency of energy utilization in silicon smelting furnace, a technology solution to recover the furnace radiant heat and exhaust energy was described in this paper; and based on the operation data of a 3200 KV•A industrial silicon smelting furnace, a 400 kW steam turbine generator unit was designed, and the economic benefit from the technology solution was also analyzed. The results show that this technology solution brings a remarkable performances of energy saving and emission reduction: about 14% of the supplying energy could be recovered; the investment payback period is between two and three years, the economic benefit from the technology solution would reach 4.72 million yuan in ten years.
