By making use of a louver concentrator test system,a study was conducted of the effect of rotating angles of blades in five stages on the performance parameters of the concentrator (dense-thin air ratio R1,resistance loss coefficient D and average concentration rate R2).

7 mm in seven and nine pass,with average pass draught of 21.

Experimental results show that the improved algorithm can extract all boundaries exactly for images with varieties of complex patterns and reduce the computation cost for the images with high run average compression ratio.

Research of high concentration ratio circulating water treatment technology in thermal power plant;

Study on industrial circulating water high concentration ratio water-saving technology and its application;

According to the dynamic test for the circulation cooling water and the corrosion speed measurement of related metallic materials,the maximum stable concentration ratio which can be achieved was introduced,and the characteristics of metal corrosion was described.

In order to study the interference of the impact type fuel rich-lean burner and the elbows, the flow field in the pipes and the concentration efficiency of coal dust has been computed by numerical simulation, in the different.
