Anti-polluting power plant using compressors and gas turbines

A versatile electric power generating plant operative during normal and peak power demand periods and also during no power demand periods comprising in combination:

• first and second continuously operating compressors having matched operating characteristics;
• supply means for selectively supplying said first compressor during normal and peak power demand periods with recycled combusted gases for pressurizing same;
• means for selectively supplying said second compressor also during normal and peak power demand periods with air for pressurizing same;
• first and second boilers having first and second combustion chambers, respectively, supplied with pressurized recycle combusted gases and air from said first and second compressors, respectively, during normal and peak power demand periods;
• an air storage tank supplied with pressurized air to store the same, means for connecting said second compressor in series with said first compressor and said first compressor with said air storage tank for pressurizing said tank with air during no power demand periods;
• means for supplying pressurized air from said air storage tank to said first combustion chamber during normal and peak power demand periods;
• first and second turbines respectively connected to the outputs from said first and second combustion chambers;
• first and second alternators respectively connected to said first and second turbines for drive thereby during normal and peak power demand periods, at least said first compressor, turbine and alternator being coupled to a common shaft for drive of said first compressor by said first alternator during no power demand periods and for drive of said first compressor and said first alternator by said first turbine during normal and peak power demand periods;
• and recycle means for receiving at least a portion of the output of said first turbine for supply of a part of said recycled gas by said supply means to said first compressor.
