FIELD: heating system.
SUBSTANCE: invention relates to a plant for coal drying using reheated steam, and in particular equipped with a multi-stage dryer that removes water contained in coal used as fuel for thermal power plants by injecting a jet of reheated steam. Installation for coal drying with using reheated steam includes a first coal dryer, a second coal dryer and a third dryer. The method is carried out by removing the moisture remaining inside and on the surface of coal used as fuel for thermal power plants in multi-stage coal dryers by using a reheated steam with a high temperature, incomplete coal combustion can be prevented.
EFFECT: coal calorific capacity is increased, the emission of pollutants is minimized, corrosion is prevented and the service life of the system is increased, the level of natural ignition is reduced due to the decrease in humidity, the efficiency of coal grinding and the distribution of heat in the power boiler during coal combustion are increased.
