燃煤工业锅炉在线能效测试的实验研究

Experimental Study on On-line Energy Efficiency Test of Coal-fired Industrial Boilers

为了实现燃煤工业锅炉能效的在线监测,自行开发研究了一套能效在线监控系统。此系统通过采集燃煤工业锅炉在线热工数据并进行分析处理实现了能效的在线监测。将其应用到燃煤工业锅炉后,分别在燃烧同种煤不同负荷和不同煤同负荷条件下与传统能效测试方法进行对比实验,发现此系统得出的能效参数结果与传统能效测试一致,说明此系统具有很高的可靠性。

In order to achieve on-line monitoring of energy efficiency of coal-fired industrial boilers,a set of on-line monitoring system for energy efficiency was developed. This system achieves on-line monitoring of energy efficiency by collecting on-line thermal datas of coal-fired industrial boilers and analyzing them. After applying it to coal-fired industrial boilers,it was compared with traditional energy efficiency test on the conditions of burning the same coal with different loads and different coal with same load. It finds that the energy efficiency parameters obtained by this system are consistent with traditional energy efficiency test. This system has a high degree of reliability.
