Abstract
Methods and apparatus are provided for regulating the percentage quantities of individual gases present in the combustion air supplied for reaction processes in metallurgy. This is achieved by utilizing molecular sieve absorption processes upon the intake air in a sequential manner to remove undesirable gases attendant with the intake air and to enhance and regulate the quantity of oxygen present. The arrangement may be operated in a continuous manner through the utilization of several molecular sieve devices wherein one of such devices may be purged for regeneration and later use by countercurrent flow of heated intake air which air has been heated by the heat derived from the metallurgical reaction process in the first place.
