In normal practice, the pulverised brown coal has a moisture content of between 10 and 20 percent when it enters the flame zone. Fluidised bed combustion of brown coal, on the other hand, subjects coal particles to a very high rate of particle-to-particle heat transfer when they enter a hot bed of fine, fluidised material.

Volatile matter (VM) is the percentage loss in mass, adjusted for moisture, when coal is heated out of contact with air under standard conditions. In this test, 1 g of sample is placed into a lidded crucible (to prevent ingress of air), which is placed in a furnace at 900 °C for 7 min or 950 °C if using the ASTM method. Moisture in the analysis sample is determined …
