<P>PROBLEM TO BE SOLVED: To rationally constitute an incinerator causing neither a hammering phenomenon nor corrosion by overcooling in a condenser even when the utilization quantity of steam used in energy utilization equipment is sharply lowered. <P>SOLUTION: The condenser 12 is arranged in a passage into which the steam discharged from a heat exchanger 11 is fed, and a by-pass passage 25 is formed to feed the steam from a feed passage for feeding the steam to the heat- exchanger 11, to the condenser 12. A control device 32 is provided for cooling by normally rotating a fan 30 for supplying the cooling air to a heat radiating passage 12A of the condenser 12 on the basis of signals from a pressure sensor 35 and a temperature sensor 37 in the case the steam is discharged from the heat exchanger 11, and reversely rotating the fan 30 simultaneously with leading the steam to the condenser 12 through the by-pass passage when the discharge of steam from the heat exchanger 11 is stopped. <P>COPYRIGHT: (C)2003,JPO |
