A mathematical model and the respective structural scheme of the convective heating surfaces of the TPP-210А steam boiler were developed as a system of interconnected heat exchangers. The interconnected convective heating surfaces are regarded as the convective heat transfer system of the boiler. The obtained results of modelling of the convective heat transfer system enable mode calculations of the dependence of the temperature and thermal mode of the heating surfaces on the variation of the heat carriers input temperature, relative changes of the heat carrier flow and heating surface area. This mathematical model is practicable for revealing possible improvements of the convective heat transfer system and for assessing the effects of the changes made to the heat transfer system basing only on the known values of the input and output temperatures of the heat carriers in the initial mode.
