摘要：
针对目前我国燃煤粉电站锅炉不能实时监测锅炉效率的不足,根据能量守恒原理提出了燃煤粉电站锅炉效率在线监测模型。通过电站DAS系统对电站锅炉效率计算模型所需的数据进行数据采集,把采集到的相关数据输入到模型中进行计算就可以实现电站锅炉运行效率的在线监测。对某台220t/h燃煤粉电站锅炉的实际测试表明,该模型可以实现对电站锅炉运行效率进行在线监测,在此基础上可以优化电站锅炉的运行或者进行针对性的技术改造,进而达到提高锅炉运行效率的目的。

Abstract: According to the conversation of energy, the on-line efficiency monitoring model of pulverized-coal fired boilers in power stations was proposed to solve the present problem that the real-time efficiency monitoring of them is insufficient in our country. The necessary data for the efficiency monitoring model were collected by the DAS acquisition system of the station and the on-line efficiency monitoring of the power station can be realized through calculating those date with the model after inputting. This model was applied to one 220 t/h pulverized-coal fired boiler to test its property and the results indicate that it can be used in real-time efficiency monitoring for power station boilers. Thus, with this model the efficiency of boilers can be improved through optimizing boilers'operation or carrying out some technology improvements aiming directly at certain problems.
