In summary, a very high temperature (above 150 °C) can result in prolonged residence time which can completely remove the moisture in the lignite. In addition, increase in temperature can decrease the hydrogen bond strength, hence decreasing the hydrogen bond concentration and intensity which ultimately decreases the briquette compressive strength.
