Jan 01, 2005 · Therefore, the recirculation of CO2 from the boiler exhaust has been rather significant (typically around two thirds of the flue gas), in order to imitate the conditions during air firing, when nitrogen is present as an inert. Most likely, a first generation of new oxyfuel boilers will also adapt this boiler design philosophy.Learn More

power plant designs of boilers, which capture CO2 and achieve zero emission of all other pollutants. In oxyfuel combustion, the oxidant, air, is replaced by nearly pure oxygen from an air separation unit (ASU) and recycled flue gas to produce a flue gas stream, which is nearly all CO2 …Learn More
Recirculated flue gases from the heat recovery boiler outlet, after being cooled and dried, are fed together with primary air into the mixer and then into the gas turbine compressor. This leads to an increase in carbon dioxide concentration in the flue gases fed into the CO2 capture installation from 7.12 to 15.7%.Learn More
