Meanwhile, the relations between finenesses of coal_dust, temperatures of flue gas at boiler exit and flyasherosion are studied.
同时，还研究了煤粉细度与炉膛出口烟温、飞灰磨损的关系，得出了一些有意义的结论。

Flue gas containing hard grain of flyash flow relative to the wall, on the wall wear called impact wear, also known as erosion. erosion.
含有硬粒飞灰的烟气相对于管壁流动，对管壁产生磨损称为冲击磨损，也称冲蚀。冲蚀。

The results show that concrete with 40 percent flyash has good properties of strength, resistance permeating of Cl-and resistance erosion of sulfate. Besides, it has a small shrinkage ratio.
