Development of oxy-fuel IGCC system with CO2 recirculation
Jan 01, 2011 · Fig.1b) shows schematics of oxy-fuel combustion capture system. The characteristic of this system is to recycle flue gas to boiler and add necessary oxygen for fuel combustion. Therefore CO 2 concentration in flue gas is about . This system doesn’t require CO 2 capture unit, after flue gas treatment, only to condense water is enough.Learn More

Oxyfuel combustion for coal-fired power generation with
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

Zero Emission Oxyfuel Power Generation for CO2 Capture
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
Investigation of a combined gas-steam system with flue gas
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
