Datang Duolun Coal Chemical Project 3 sets of Shell Six Burner gasifiers treat about 10% of brown coal with water content, but the local brown coal moisture content is up to 40%. In the face of this problem, Datang passed a lot of research at the beginning of the construction of coal chemical projects and found that the coal drying technology available in China cannot meet such a large scale whether it is rotary drum drying technology, spill drying technology or boiling bed drying technology. Lignite drying requirements. Through technical demonstration, the company decided to independently research and development, technical personnel for the first time put forward a large-scale tube drying technical plan and equipment development program to reduce lignite moisture, try to indirect heat exchange through the shell and tube heat exchanger, so that the use of low-quality brown coal moisture content to use index.
In September 2006, at the test base of Datang International Xiahuayuan Power Plant, the pilot plant for pre-drying lignite with a processing capacity of 6 tons per hour was installed and tested, and a number of parameters were tested and operated. The equipment operation parameters laid the foundation for the large-scale industrial application of lignite pre-drying equipment in Datang Duolun coal chemical project. In this device, the heat transfer medium is not in direct contact with coal, which makes the whole drying process safe and reliable, and solves the safety hazards brought about by direct drying of coal with low ignition point.
In June 2011, 15 casing drying equipments were put into operation at the Duolun coal chemical project site. In December 2012, the trial production was transferred to the normal production operation. After drying, the inferior lignite fully satisfied the coal used in the coal gasification plant of the project. Quantity, particle size, moisture index.
At present, Duolun Coal Chemicals site 15 casing drying equipment is running normally, each set of dryer drying 46 tons of coal per hour, out of the dryer coal particle size is less than or equal to 6 mm, the utilization rate of 99%.
Datang Duolun broke the high-water brown coal dry
The lignite drying process equipment independently developed by Datang Duolun Coal Chemical Company was recently granted a national invention patent. Applying this patent Datang Duolun Coal Chemical Company's coal pre-drying plant in 2013 used a total of 1.728 million tons of high-moisturized lignite to ensure the adequate supply of three dry gasifiers.
