摘要
针对发电厂大型煤粉锅炉,从理论上对传统热力计算方法相关参数、关联式进行改变,使其适用于空气分离/烟气再循环技术:将改变后的计算方法应用于煤粉在O_2/CO_2气氛燃烧中,将求解结果与在常规空气中燃烧的结果进行对比,重点分析烟气成分变化对各参数及炉膛换热的影响,目的在于寻求煤粉在O_2/CO_2方式下燃烧的热力计算方法,为采用该燃烧技术的锅炉的设计和运行提供参考。
In the light of large capacity pulverized coal boiler in a power plant, the conventional thermal calculation methods and correlation have been changed to make it applicable to air separation/flue gas recycle technology theoretically, which has been applied to pulverized coal combustion in O2 / CO2 atmosphere with different proportion. The combustion result in air is compared with the experimental conclusion, the effect of flue gas component＇s change on the parameters is analyzed emphatically, hoping to seek for a thermal calculation method for coal combustion in O2 / CO2 atmosphere, offer a reference for the boiler design and operation by O2/ CO2 combustion technology.
