How to avoid the waste of lignite resources

Lignite is a fossil fuel that will become increasingly important in the future because it is an alternative raw material for the oil, gas, energy, and chemical industries. The conversion rate of lignite resources on-site utilization is not high, which will cause resource duplication and waste. The lignite upgrading can be divided into two processes of dehydration and pyrolysis according to different processing methods. Dehydration is usually carried out before the lignite pyrolysis process, and lignite drying and dehydration is the most common Lignite Upgrading Process.

At present, the lignite upgrading technology is mainly based on lignite drying. Jiutian Lignite Upgrading Production Line mainly adopts the rotary drum lignite drying upgrading process. Under the condition of ensuring the quality of the dried lignite is unchanged, the low-temperature four-stage drying process is adopted. Reduce the sulfur content and ash of lignite and increase the calorific value of lignite to meet the requirements of coal for power plants. The lignite upgrading process can reduce the moisture of the lignite to less than 12%, thereby reducing the transportation cost, and at the same time processing the shaped coal to solve the problem that the lignite is liable to spontaneous combustion.

Jiutian Lignite Drying System has stable equipment performance, convenient operation and maintenance, energy-saving and environmental protection, high efficiency, and preferential prices. Welcome to consult online for more information.
