Abstract

The shortcomings of the applied methodology of design thermal calculation of duct heaters are noted, it is shown that the replacement of the heat transfer coefficient of the plant with the heat transfer coefficient of the duct heaters can lead to an inadmissible underestimation of the required heating surface of the plant, which in extreme operating conditions will inevitably cause its freezing and failure.
