Abstract: The present invention provides an air supply assembly for providing air to an energy heat converter, the air supply assembly comprising an air inlet opening; an air outlet opening; and a metal element positioned in an air flow path between the air inlet opening and air outlet opening, wherein, when air which flowed through the metal element is used for combustion in the energy converter, the thermal efficiency of the energy converter increases, the fuel consumption of the energy converter is reduced and/or the air pollution created by the energy converter is reduced. The present invention also provides a method for reducing fuel consumption of an energy converter and a method for reducing air pollution created by an energy converter, the method comprising passing air through a metal element and using the air for combustion in the energy converter.
