<P>PROBLEM TO BE SOLVED: To improve the efficiency of heat recovery from exhaust steam of a superheated steam system used for carbonization of waste or the like. <P>SOLUTION: The superheated steam system comprises a saturated steam generator 1 for heating a given quantity of internally stored water to generate saturated steam, a first superheater 12 for superheating the saturated steam generated by the saturated steam generator 1, a pump 13 for drawing in, compressing and discharging the superheated steam superheated by the first superheater 12, a second superheater 14 for superheating the superheated steam discharged from the pump 13 and pressurized by the pump 13, a treatment chamber 5 for leading in the superheated steam superheated by the second superheater 14, treating a target of treatment in the chamber and exhausting waste steam after the treatment, and a heat exchanger for effecting heat exchange between the waste steam exhausted from the treatment chamber 5 and the water in the saturated steam generator 1. The condensation temperature of the waste steam in the heat exchanger 8 can be increased beyond the evaporation temperature of the water in the saturated steam generator 1, so that the efficiency of heat recovery from the exhaust steam can be improved. <P>COPYRIGHT: (C)2003,JPO |
