At the same time, the paper gives deep analysis about the optimization operation of the low-press economizer. 同时，本文对低压省煤器的优化运行方面做了深入细致的研究工作。
The test indicates that the turbidity varies with the condition of raw water in a narrow range, and it profits to realize optimal operation in manufacture. 试验表明虽然该浊度值同原水水质条件相关，但变化幅度不大，有利于在生产上实现优化运行。
