The invention discloses a boiler combustion monitoring method and device. The method comprises the steps that smoke is injected into a monitoring unit; detecting the carbon dioxide concentration at the gas inlet end and recording data; oxygen is injected into the reaction furnace, so that carbon particles in the flue gas can be fully combusted in the furnace; detecting the concentration of carbon dioxide at the gas outlet end and recording data; and the amount of residual carbon carried in the flue gas is determined according to the concentration difference of carbon dioxide at different ports. The method has the beneficial effects that by detecting the carbon content of the fly ash in real time, a worker can conveniently and quickly record data and feed back maintenance, guiding operation is facilitated, the air-coal ratio is correctly adjusted, and the boiler combustion control level is improved; the index of the carbon content of the fly ash is reasonably controlled, the power generation cost is reduced, and the economical efficiency of unit operation is improved.
本发明公开了一种锅炉燃烧监测方法及装置,包括对监测单元注入烟气;对进气端二氧化碳浓度进行检测并记录数据;通过在反应炉中注入氧气使烟气中碳颗粒能够在炉内充分的燃烧;对出气端二氧化碳浓度进行检测并记录数据;通过不同端口的二氧化碳浓度差异确定烟气中携带的余碳多少。本发明的有益效果为通过实时检测飞灰含碳量,便于工作人员快速记录数据和反馈维护,有利于指导运行正确调整风煤比,提高锅炉燃烧控制水平;合理控制飞灰含碳量的指标,有利于降低发电成本,提高机组运行的经济性。
