Abstract
Arrangement for preparing dry hot compressed air to be supplied to blast furnace, wherein a heat exchanger and a dehydrater assembly comprising a gas permeable regenerative moisture absorbing rotor are arranged in the air passage from blower to hot air furnaces so that the hot compressed air from the blower may be used to heat the dehydrated air and to regenerate the rotor. Air leakage between regenerating and dehydrating zones in the dehydrater is prevented by sealing those clearances where otherwise such leakage would occur by packing elements to form sealed spaces and externally introducing dry pressurized air into each of said spaces.
