摘　　要：针对以CO_2减排为主要目的的富氧燃烧电站锅炉,对其风烟燃烧系统稳态过程循环烟气量和烟气组分体积分数进行建模分析,给出了风烟燃烧系统运行工艺参数和烟气调节变量之间的相互作用关系.结果表明:由模型所得烟气各组分体积分数与实测数据的吻合度较高,两者误差在5%以内;该模型为富氧燃烧系统的工艺设计和运行优化提供了合理有效的定量依据,同时也为风烟燃烧系统相关运行参数的测点配置、仪表选型、变量调节和设备操控提供参考.For oxy-fuel combustion boilers aiming at reducing CO2 emission, a steady-state model was es- tablished tomeasure the flow rate and component of the gas in the air/gas combustion system, and subse- quently to find the interrelation between the system operating parameters and the governing way of gas variables. Results show that the gas flow rate and its component calculated by the model are close to actual measurements, with both errors less than 5 %. The model is therefore proved to be reasonable and effec- tive in providing quantitative basis for the design and running of oxy-fuel combustion systems, which may also serve as a reference for relevant measurement configuration, instrument selection, quantitative gover- ning and device manipulation of air/gas combustion systems.
