China is currently the world's largest smelting base for ferroalloys such as silicon and ferrosilicon. However, the existence of this high-energy-consumption and high-pollution smelting process puts great pressure on the country's energy conservation and environment. Under the dual pressure of energy shortage and environmental protection, our company has developed a series of arc furnace waste heat boilers. The boiler adopts a waste heat deaerator with its own flue gas to protect the bottom dust collection system and improve the waste heat utilization efficiency. And the use of our patented steel ball ash cleaning system, so that the boiler can run smoothly.
