摘要
Power generation method based on gaseous fuels and a combined nitrogen free thermal cycle with gas (GT) and steam (ST) turbines, the working medium of said GT being CO2 and steam produced by combustion of any gaseous fuel with oxygen in said GT combustor during simultaneously feeding a part flow of compressed flue gas from a steam generator utilising the GT exhaust for steam production, which steam generates power in an ST. The rest of flue gas from said generator is utilised for hot-water production in a heat recovery unit (HRU), the hot-water partly being utilised for moistning said flue gas before compression, for feed water etc. The flue gas from HRU is moist CO2, which can be liquefied and used for EOR, for chemicals and for dumping in the oceans etc. The method's gross efficiency including 02 generation is 60 %; the net efficiency, also including CO2 liquefaction, is 58 %.
