Discuss the issue of waste heat utilization from metallurgical rotary kiln slag
Thread Content
Valuable metals such as zinc oxide are recovered through volatilization in a rotary kiln. The temperature of the slag discharged from the kiln head is over 800°, and it contains more than 10% coke. Is it possible to modify a boiling furnace into a hot air furnace? Using high-temperature kiln slag as a heat source?
At present, this technology is virtually non-existent in China; I am also working on its research and development, and I hope we can exchange more ideas
