SOLUTION: An apparatus which generates hydrogen chloride and sulfur dioxide, for example, a dry distillating furnace or a combustion furnace 8 is generally operated at near 500°C, and a gas 6 containing hydrogen chloride gas and sulfur dioxide gas in addition to hydrogen, nitrogen, carbon monoxide, or the like is generated by the operation. The gas 6 is conducted to a desalting and desulfurizing tower 1. For the desalting and desulfurizing tower 1, a desalting and a desulfurizing agents 2 are filled inside, and the gas 6 is ventilated from a lower part of the tower 1. As the desalting and desulfurizing agent 2, CaO, Ca(OH)
2 , or the like are used. After reaction-treating the gas 6 in the desalting and desulfurizing tower 1 in the state wherein an exhaust gas temperature is kept within a range of 350 to 550°C, the gas 6 as a treating gas 5 is sent to an exhaust gas boiler 9 and burnt.
