What is a lignite dryer? Market analysis of lignite dryers

Lignite dryer, also known as firewood coal, is a low grade coal with a brownish black degree of coalification between peat and asphalt coal. Non adhesive, with a moisture content of up to 30%~60%; High volatile matter; Low density, prone to weathering and fragmentation in the air, strong chemical reactivity, and poor thermal stability.

market analysis

Lignite has the advantages of cleanness, low volatility and low sulfur, but it also has the disadvantages of high humidity, low ignition point and large carbon dioxide emissions. Compared with bituminous coal and Anthracite, lignite has the advantages of low price and high reactivity, but its calorific value is relatively low and its water content is high, generally 30-60%. The moisture in lignite increases transportation costs, affects boiler operation, reduces power plant efficiency, and increases greenhouse gas emissions. Therefore, the development of lignite drying, drying, and upgrading technologies and equipment is the key to the clean and effective utilization of lignite.
