Abstract
The invention places a concentration averaging device in an inlet line leading to an air treatment system. The device includes an adsorbent material which has the quality of increasing its equilibrium concentration of impurities with increasing percentage or concentration of impurities in the air stream. In this way, the concentration device tends to 'average' the amount of impurities in the air stream delivered to the air treatment system. When used on an oxidizer, as an example, this allows the use of smaller combustion chambers, and reduces the fuel requirements for operation of the system.
