The paper is devoted to the performance estimation of a recuperative heat exchanger under conditions of fouling and presence of inert gases. Calculations were performed using three different approaches based on: the global, lumped-parameter and 1D models. With the use of 1D model the influence of fouling and air-concentration on the distribution of both the pertinent heater temperatures and heat flux were investigated. It appeared that air plays a dominant role in the case when its concentration is sufficiently high. It may be concluded that the proposed 1D model provides a very efficient method for heat transfer evaluation of heat exchangers.
