That is, the combustion air 5 supplied to the combustion furnace 3 as a supporting gas required for combustion does not need to be specially pressurized simply to generate SO 2 gas as a process gas for sulfuric acid production. In the combustion of the molten sulfur 2 by the combustion air 5 having a low pressure, the blower 4 merely guides the supply pressure to the combustion furnace 3 at a feed pressure slightly higher than the atmospheric pressure. Since it is not possible to generate SO 2 gas 6 having a pressure high enough to drive a generator or the like without hindrance, a technique for specifically recovering kinetic energy and heat energy of SO 2 gas 6 from combustion furnace 3 is not described. However, the design concept of recovering such kinetic energy and thermal energy was completely lacking.
