Claims
- 1. A thermal power generation plant of a closed combined cycle structure comprising:
- a combustor in which a fuel is burnt in the presence of an oxygen;
- a fuel supply means connected to said combustor to supply a fuel therein;
- an oxygen supply means connected to said combustor to supply an oxygen therein;
- a turbine operatively connected to said combustor to be driven by combustion gas from said combustor;
- a generator operatively connected to said turbine;
- a waste heat boiler connected to said turbine which exhausts turbine exhaust gas mainly composed of carbon dioxide and water component;
- a condenser connected to said waste heat boiler through a line for condensing the water component in a cooled exhaust gas from said waste heat boiler, a sulfur oxide removing means being incorporated in the line connecting said waste heat boiler and said condenser;
- a water-gas separator connected to said condenser for separating condensate and gas component mainly composed of carbon dioxide, said water-gas separator being connected to said waste heat boiler to feed the condensate thereto;
- a compressor connected to said water-gas separator through a line for receiving said gas component mainly composed of the carbon dioxide and for compressing said gas component and supplying it directly to said combustor;
- a steam turbine connected to said waste heat boiler and connected to said generator through a driving shaft; and
- a condensor connected to said steam turbine and said waste heat boiler through a line through which said stream turbine, said condenser and said waste heat boiler constitute a closed cycle.
- 2. A power generation plant according to claim 1, wherein an excessive carbon dioxide removing means is incorporated in a line connecting said water-gas separator and said compressor.
- 3. A power generation plant according to claim 1, wherein a condensate recovery means is connected to said water-gas separator.
