FIELD: heating systems.
SUBSTANCE: invention refers to equipment intended for drying plant raw materials and can be used in agricultural industry. Device includes furnace 1, steam boiler 3 located above furnace. Steam pipeline 6 tapped from upper part of steam boiler 3 is equipped with smooth steam flow control valve. Steam turbine 8, centrifugal fan 13 and electric power generator 14 are located in series on one shaft 11. Steam turbine 8 is connected through steam pipeline 6 to steam boiler 3, and centrifugal fan 13 is connected via air ducts to drying chamber 16 and furnace 1. On stack 21 there installed is bypass valve 20, and stack 21 passing through it is divided into two pipes 18 and 19, which are located horizontally one above the other in drying chamber 16. Between pipes 18 and 19, parallel to them, there installed is meshed channel 17. Electric power generator 14 is equipped with control unit 24.
EFFECT: improving drying quality.
