The invention relates to an arrangement for de-icing railway trucks and ore concentrate in railway trucks. The arrangement comprises a tunnel (2) having a number of discharge openings (3) for heated air which is used for de-icing and at least one exhaust opening (4) for used air. An air heater (5) is in communication with the discharge openings (3) through a supply air duct (6). The arrangement further comprises a water supply device arranged to supply water to the air heater (5) and/or the supply air duct (6). The capacity of the air heater (5) is high enough to heat the air to a temperature sufficient for vaporizing at least a portion of the water. The invention also relates to a corresponding method for de-icing.
Device for de-icing railway trucks (1) and/or dressed ore in railway trucks, which device comprises a tunnel (2) provided with a plurality of injection openings (3) for heated air to be used for de-icing and at least one evacuation opening (4) for used air, which device furthermore comprises a hot-air generator (5) that, by supply-air duct means (6), communicates with the injection openings (4), characterized in that the device furthermore comprises a water supply device arranged for the supply of water to the hot-air generator and/or the supply-air duct means, and in that the hot-air generator (5) is arranged with a capacity to heat the air sufficiently much so that at least a part of the supplied water should be evaporated.
Method for de-icing railway trucks and/or dressed ore in railway trucks, wherein each railway truck is driven into a tunnel and air is heated by a hot-air generator and the heated air is blown through injection openings against the railway trucks, characterized in that water is supplied to the hot-air generator and/or a supply-air means in such a way that it at least partly is evaporated by the same and then goes along with the heated air.
