[0002] my country has a large reserve of lignite, with proven reserves of about 210 billion tons, accounting for 13% of the country's coal reserves. This type of coal has a high moisture content (35% to 50%), low calorific value, high volatility, and is prone to spontaneous combustion. Large-scale development and utilization and conversion and utilization as raw materials are subject to great restrictions. In order to make efficient use of lignite, the most economical method is to dry and dehydrate it first.
