摘要

A novel technique for the quick measurement moisture content of coal powder by microwave was studied. The effects of the various moisture contents on the measurement results were also discussed. The experimental results show that the standard deviation is less than 0.36% when the moisture content of coal powder is 0.74%～16.90% and the standard deviation is less than 0.16% when the moisture content is 0.31%～1.49%. The experimental results indicate that a process of quick measurement moisture content of coal powder by microwave is practical.
