What is Coal Analysis? (with pictures)
Jul 27, 2020· Coal analysis attempts to gauge how much inherent moisture is in a particular sample. As logic would dictate, the less moisture in a piece of coal, the better. The volatility of coal is measured by the proportion of volatile matter, which includes various types of hydrocarbons and sulfur, in a sample.Get Price

The sample of coal is heated at 105 to 110 °C in a stream of oxygenfree, dry nitrogen and the moisture driven off is collected in an absorption tube containing a desiccant. The increase in mass of the absorption tube (after deducting the result of a separate blank determination) is due to moisture in the sample of coal.Get Price

Coal Testing Definition Spectro
1. Moisture The importance of determining ‘Moisture’ in coal arises from the fact that all coals are mined in very wet conditions. This moisture is water held within the coal itself, and is also known as ‘inherent moisture’. ‘Adventitious moisture’ refers to Groundwater and other extraneous moisture, which gets readily evaporated.Get Price
