ABSTRACT:
An apparatus is provided for regulating the percentage quantities of individual gases present in the combustion air supplied for reaction processes in metallurgy. A molecular sieve absorption material is used on the intake air to absorb the inert constituents to thereby enhance the quantity of oxygen present. The apparatus utilizes several molecular sieve materials in a continuous manner such that one of the devices containing the molecular sieve material is being purged for regeneration while another device is absorbing the inert constituents, while yet another device is cooling, i.e., getting ready for the absorption operation. The countercurrent flow of heated intake air, which air is derived from the metallurgical reaction process, is used in the apparatus for regenerating the molecular sieve material.
