ABSTRACT:
Apparatus for dehydrating air to be supplied to a blast furnace comprising a dehydration assembly wherein intake air is dehydrated by contact with a circulating hygroscopic liquid and a regeneration assembly wherein the liquid is regenerated by contact with air under heating with steam, characterized in that a cylinder through which a part of the circulating liquid is caused to flow is provided for comparing the pressure of the liquid with a reference liquid to detect the concentration of the circulating liquid, the regeneration assembly is divided into a plurality of independently operable units each having regeneration means, means for controlling the steam flow rate according to the detected concentration, means for controlling the liquid flow rate according to the detected concentration, and at least one heat exchanger for transferring sensible heat between at least one fluid entering said regeneration means and at least one fluid leaving said regeneration means.
