The technical features of O2/CO2 combustion mode have been presented
each heat loss and thermal efficiency of boilers for 300 MW units in one power plant under O2/CO2 combustion mode being calculated by adopting method stiplated in ASME PTC4-1998
and compared with that in air atmosphere condition.The results show that the thermal efficiency of boiler can be greatly improved by using the O2/CO2 combustion mode
and the high CO2 concentration in flue gas can reduce the cost for separation and recovery of CO2.In addition
through comparison of boiler thermal efficiency under different oxygen concentration
it shows that the volume percentage of oxygen should not greater than 30% in using the O2/CO2 combustion mode.
