Calcium sulfate is reduced into calcium sulfide by natural gas after coke reforming, and the calcium sulfide is recycled for reaction. However, the above method has a major problem in that the generated sulfur vapor adheres to the inner surface of the pipe during the transfer to the sulfur condenser, thereby causing clogging of the pipe.
