BROWN COAL SAMPLING, ANALYSIS AND COMPOSITION - .

There is a major uncertainty with the determination of the moisture in an air-dried analysis sample of Victorian brown coal due to the nature of the remaining moisture in the sample. When air-dried, the coal will generally have a moisture content between 10% and 15% which is dependent upon the properties of the coal and upon the ambient conditions of temperature and humidity (refer Chapter 3 ).
