Through appearance inspection, wall thickness measurement, EDS analysis and X-ray diffraction, the corrosion cause of the coaleconomizer tube is analysed.
通过外观检验、壁厚测量、扫描电镜、能谱和X射线衍射，对省煤器管腐蚀原因进行了分析。

The low-pressure economizer installed in thermal system of power stations gives a useful option for reducing the coal consumption rate .
在电厂的热系统内增设低压省煤器是降低发电标准煤耗的有效措施。
3
The gas producer is equipped with adjustable economizer baffle. The coal layer is even and the fuel thickness of the furnace profile is unified so the gasification efficiency is greatly enhanced.
