Design of Light Moisture Tester and its Application in Tiefa Coal Industry Group

Abstract:

This paper introduces the research and design of a light moisture tester. In the coal quality analysis field, moisture test most of the use of infrared heating pipe heating or drying box to measure, low heating rates, nitrogen through a single mode, before heating furnace uniform nitrogen filled with test conditions and have the test conditions, the same way caused by nitrogen, nitrogen waste. Based on this study, the heating pipe comprises an infrared tube into a light tube, the heating rate is improved; the general nitrogen control size flow switching mode using 2.5min before the experiment, large flow quick heating furnace filled with nitrogen, achieved through experimental conditions drying nitrogen, open a small flow, keep the atmosphere. The improved design of a light moisture meter analysis of water air drying method precision test, analysis of water air drying method accuracy experiments, 6 water - air drying method of precision experiment, 6 water - air drying method accuracy experiments, analysis of water through nitrogen drying method precision experiment, analysis of water. Nitrogen drying method accuracy experiments, Ȼ 6 full water through nitrogen drying method precision experiment, Ȼ 6 full water through nitrogen drying method accuracy experiments, results in line with national standard test, repeatability. Instrument for field application test in Tiefa Coal Industry Group, good test effect.
