PROBLEM TO BE SOLVED: To provide a heat and cold simultaneous generation system improved in steam utilization efficiency, which obtains heat and cold simultaneously. SOLUTION: The heat and cold simultaneous generation system has a boiler, a superheater, a steam turbine, and an expander. The system is provided with a compressor for the superheater and a compressor for the boiler, both driven by the power generated by the steam turbine and expander. The superheater heats steam generated by the boiler by causing the combustor for superheater to burn the air supplied from the compressor for superheater and the fuel for superheater; the combustor for boiler introduces combustion gas from the superheater and air supplied from the compressor for boiler and burns them with the fuel for boiler, thereby causing the boiler to generate steam; and the above superheater heats the steam. The heated steam is led to the steam turbine to drive the steam turbine and the exhaust gas emitted from the boiler is led to the expander to drive the expander. The steam emitted from the steam turbine and the gas emitted from the expander are made available as the heat and cold, respectively. COPYRIGHT: (C)2009,JPO&INPIT
