The paper presents the results of calculations related to the flow analysis of a tube bank taking into account the partial pressures of gases flowing through the condenser. Different mass share of the gas not condensing in the heat exchanger upstream to the first row of tubes and the partial pressures of water vapor and air have been taken into account. The value of the partial pressures of gases, pressures drop, temperature, velocity, Reynolds number, and air share in the subsequent rows of tubes have been calculated. This study is a basis for the analysis of heat exchange in the condenser considering the influence of the noncondensing gas. The increase in the share of air in the following rows of tubes results in an increase in the thermal resistance and condensation of increasingly lower mass of water vapor.
