Advantages of drying Lignite

High moisture content and low calorific value are the main features of lignite.In addition,It also has the disadvantages of low thermal efficiency, greenhouse gas emissions, weathering and spontaneous combustion, high transport costs, difficult to long-distance transmission and storage. To solve these problems,Dongding has developed specialized drying lignite production line (Patent No. ZL 2013 2 0034342.6), which can guarantee the quality of lignite after reducing the moisture content of lignite, enhancing brown coal calorific value, improving combustion efficiency and making more full use of coal resources . The system is a major breakthrough in the field of coal drying, greatly expanding the use of lignite.

Advantages of drying Lignite

1. Reasonable system configuration, equipped with special heat source spray furnace, which can use the dry lignite powder as fuel, reducing costs.

2. After drying the lignite is not regurgitation, after drying the pulverized coal has a large physical and chemical changes, eliminating lignite regurgitation suction, realizing the long-distance transportation of lignite.

3. High efficiency.Burnout rate of heat source used pulverized coal up to 99%.

4. High safety. The unique sealing structure of the discharge, and the entire non-oxidizing negative pressure operation, eliminate the possibility of lignite combustion and explosion, safe and reliable.

5. Low investment in equipment and low operating costs, can recoup investment in a relatively short period of time.
