摘要
介绍美国BOARDMAN燃煤电厂采用数字式控制系统和输入/损失算法软件,找出锅炉热量和效率损失区域的方法。由于14个氧量探头“看不见”后墙燃烧器,锅炉运行有20%的空气内漏。移动这些探头,增加另外12个,解决了此问题。
It?s introduced that the way to identify areas where Btus and percentage points in efficiency were lost by using Input/Loss Method (ILM). The boiler was operating with 20% air in-leakage because the 14 O probes in its exit flue 2 couldn?t òseeó burners on the boiler's back wall. Moving those probes, and adding another 12, solved the problem.
