Aiming to the performance analysis of boiler with supercritical carbon dioxide (S-CO2) cycle, the boiler performance evaluation index system is built by taking the gas-fired boiler used in the 5 MW S-CO2 Brayton cycle pilot unit at Xi'an Thermal Power Research Institute Co., Ltd. as the research object. The core performance indexes of S-CO2 boiler include the fuel efficiency of boiler, the ratio of heat absorption over the input heat for each heat exchanger, the performance of air preheater, the pressure drop of working fluid system, the NOx emission concentration, and others. The fuel consumption and excess air coefficient are calculated via the measurement of oxygen concentration. Meanwhile, the calculation method of heat loss due to exhaust gas is improved. The ratio of heat absorption over the input heat for each heat exchanger is introduced, which shows the contribution of each heat exchanger on heat absorption process. Finally, the calculation process is integrated becoming to an executable program, and it is applied in the running and monitoring procedures. An operating case showed that, for the research object, the actual condition is basically the same as that of the design parameters. The finally calculated boiler fuel efficiency is 92.05% without correction and 93.79% with correction, the later is similar as the designed value (93.53%).

以超临界二氧化碳(S-CO2)布雷顿循环发电机组中主设备S-CO2锅炉作为研究目标,以5 MW试验机组作为研究对象,开展S-CO2锅炉性能指标评价体系研究。S-CO2锅炉的核心性能指标为锅炉燃料效率、换热面吸热量占比、空气预热器性能、工质系统压降和锅炉NOx排放浓度等。燃料效率计算中,通过计算尾部烟气含氧量进行过量空气系数推算燃料消耗量和风量,并改进排烟热损失的计算方法。引入了换热面吸热量占总吸热量比值作为S-CO2锅炉工质侧性能考核指标。建立了5 MW S-CO2燃气锅炉性能指标评价体系并集成程序且完成案例分析。实际工况与研究对象的设计参数(设计效率93.53%)基本相当,最终计算获得锅炉燃料效率未经修正为92.05%,锅炉燃料效率修正为93.79%。

以超临界二氧化碳(S-CO2)布雷顿循环发电机组中主设备S-CO2锅炉作为研究目标,以5 MW试验机组作为研究对象,开展S-CO2锅炉性能指标评价体系研究。S-CO2锅炉的核心性能指标为锅炉燃料效率、换热面吸热量占比、空气预热器性能、工质系统压降和锅炉NOx排放浓度等。燃料效率计算中,通过计算尾部烟气含氧量进行过量空气系数推算燃料消耗量和风量,并改进排烟热损失的计算方法。引入了换热面吸热量占总吸热量比值作为S-CO2锅炉工质侧性能考核指标。建立了5 MW S-CO2燃气锅炉性能指标评价体系并集成程序且完成案例分析。实际工况与研究对象的设计参数(设计效率93.53%)基本相当,最终计算获得锅炉燃料效率未经修正为92.05%,锅炉燃料效率修正为93.79%。

Aiming to the performance analysis of boiler with supercritical carbon dioxide (S-CO2) cycle, the boiler performance evaluation index system is built by taking the gas-fired boiler used in the 5 MW S-CO2 Brayton cycle pilot unit at Xi'an Thermal Power Research Institute Co., Ltd. as the research object. The core performance indexes of S-CO2 boiler include the fuel efficiency of boiler, the ratio of heat absorption over the input heat for each heat exchanger, the performance of air preheater, the pressure drop of working fluid system, the NOx emission concentration, and others. The fuel consumption and excess air coefficient are calculated via the measurement of oxygen concentration. Meanwhile, the calculation method of heat loss due to exhaust gas is improved. The ratio of heat absorption over the input heat for each heat exchanger is introduced, which shows the contribution of each heat exchanger on heat absorption process. Finally, the calculation process is integrated becoming to an executable program, and it is applied in the running and monitoring procedures. An operating case showed that, for the research object, the actual condition is basically the same as that of the design parameters. The finally calculated boiler fuel efficiency is 92.05% without correction and 93.79% with correction, the later is similar as the designed value (93.53%).
