摘要

介绍了O2/CO2燃烧方式的技术特点

采用ASMEPTC4—1998中计算锅炉热效率的热损失法对某电站300MW机组锅炉在O2/CO2和空气气氛下的各项热损失和锅炉热效率进行了计算比较。结果表明

采用O2/CO2的富氧燃烧技术可明显提高锅炉热效率

而且烟气中高浓度的CO2降低了分离回收CO2的成本。另外

通过对比不同氧气浓度下的锅炉热效率

表明采用O2/CO2燃烧方式时

O2的容积百分数不宜大于30%。

Abstract

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.
