THERMAL POWER PLANT WITH SMALL emission of pollutants

摘要

A method for the generation of electrical power from a carbonaceous fuel, wherein the fuel is combusted in presence of oxygen under increased pressure in a combustion chamber is described. The exhaust gas from the combustion is separated into a COSUB2 /SUBrich fraction that is handled so that it does not escape to the surroundings, and a COSUB2 /SUBdepleted fraction that is expanded over one or more turbines to power other processes and/or generation of electrical power, before the gas is released into the surroundings, where the temperature in the combustion chamber is reduced under the generation of steam that is expanded over steam turbines connected to electrical generator for the generation of electrical power. Additionally a thermal power plant for the performing of the method is described.
