SYSTEM FOR COAL DRYING WITH USE OF SUPERHEATED STEAM Russian patent published in 2015 - IPC F26B15/24 

FIELD: heating.

SUBSTANCE: system for coal drying with use of superheated steam contains a steam boiler to generate superheated steam due to combustion of the fuel supplied from gas tank, and heating of water supplied from the water tank, high temperature air supply device to generate high temperature air due to combustion of fuel supplied from gas tank, and further blowing by air of the dryer to remove water from coal surface, transporting coal from the coal storage using the conveyor in form of the trough and distributing using the arranging device over the steam conveyor, one or more high temperature air drying devices to remove the water contained in coal using high temperature air, while transporting coal passing through the device for drying by overheated steam; and device for natural drying, where water from coal is evaporated naturally at room temperature. The system prevents incomplete coal combustion due to removal of water present inside and outside the coal fuel used by thermoelectric power generating system.

EFFECT: heat value of coal improves, minimum release of contaminants, corrosion is prevented, and system reliability is improved, besides increased use of low quality coal that has low demand.
