Abstract:

Based on the performance test of a 5E-APS Ⅱ automatic sampling machine of a 2×660MW coalfired power plant, reliable performance test methods are studied. A set of fair and operable automatic sampling machine performance evaluation system is explored and set up. It can determine whether the precision of the sampling machine and the system bias are in line with the national standard requirements, ensure inspection on coal quality of thermal power plants and sample making process rigorous and traceable.
