摘　　要：称重法飞灰测碳仪是目前电厂较为理想的在线监测飞灰可燃物的设备,以某公司研发的悬臂式失重法飞灰测碳仪为对象,介绍其工作原理,指出了目前存在的问题,如元器件长期工作的使用寿命有限、机械老化、长期在线监测可靠性降低等问题。为此,提出了一种基于神经网络预测和飞灰测碳仪实测相结合的智能控制模式,能在减少测碳仪动作频率的同时,延长设备使用寿命,对其进行有效的改进。The burning method of measure carbon technology is a classic method at present,taking the company development cantilevered weight-loss method of fly ash carbon instrument measured object,given its principle of work meanwhile points out the existing problems,such as components of the service long time work problems and mechanical ageing,reduce the long-term reliability of on-line monitoring.Therefore,this paper proposes a theory:Combine the neural network prediction and the fly ash carbon instrument measured.The new intelligent control mode,the machine operation has made a lot of improvement.
