FIELD: heating.SUBSTANCE: drier includes drier housing (12), in which forced circulation of heated air is performed, exhaust pipeline (20) for removal of air from drier housing (12), firing device (14) connected to exhaust pipeline (20), which serves for further heat treatment of the air removed from drier housing (12), as well as for supply of hot air to heat exchanger (18). Heat exchanger (18) is made so that heated fresh air is supplied to drier housing (12), and with that, at least one heating device (16) is related to drier housing (12) for heating of forced circulating air in drier housing (12). Air supply device (34) for burning operation of heating device (16) is interconnected with drier housing (12).EFFECT: operation of a drier both in a full load mode, and in a partial load mode; reduction of power consumption.11 cl, 4 dwg |
