Lignite drying machine adopts hightemperature and rapid drying process, which makes the utilization of air temperature increase 40 percentage points than ordinary temperature drying methods. Its heating system has up to 90% thermal efficiency, which allows integrated thermal efficiency up to 73 %.
This paper describes results of field tests, conducted with dried lignite coal at a 550 MW unit in North Dakota, and a coal drying process that uses a lowgrade waste heat to evaporate a portion of fuel moisture from the lignite feedstock.
Coal Moisture: The degree of drying, and therefore the required mill outlet temperature (from 6580 0 C) will depend upon the type of coal ground. Some residual moisture in fine coal is recommended (Graph below) to minimize the potential of spontaneous ignition of fine coal, which will again vary for different coal types as below:
In the first phase, a 115ton/hr prototype capable of drying up to 25% of the lignite fed to Coal Creek Station''s 546MW Unit 2 was designed, built, and tested.
Predrying of raw coal has the potential to increase efficiencies by up to 10% for plants that burn moist lignite with a water content of over 45%. Two processes for external coal drying are currently being developed. The first is a mechanicalthermal drying process that mechanically dries raw coal that has been heated to around 140 to 200 °C.
