FIELD: heating. ^ SUBSTANCE: invention relates to electric power station with reduced CO2-content and method to produce electric power from coal fuel. Gaseous combustion products are additionally cooled and separated into low CO2-content and high CO2-content flows in CO2-trap. Low CO2-content flow is heated in expanded in turbine to generate electric power and, thereafter, low CO2-content flow is discharged into ambient medium. Note here that high CO2-content flow is separated into flow to be stored or discharged, and flow to be returned into combustion chamber. Note also that at least a fraction of high CO2-content flow returned into combustion chamber is mixed with coal fuel to forced into combustion chamber together with coal fuel. ^ EFFECT: possibility to use CO2 as fuel propulsor and to prevent fuel preignition. ^ 11 cl, 6 dwg |
