Radiative Component and Combined Heat Transfer in the Thermal Calculation of Finned Tube Banks

Popis výsledku v původním jazyce

For more exact calculation of combined heat transfer in case of finned tube banks (e.g. in the connective section of a furnace), the radiative heat transfer cannot be neglected. A new method for relatively simple calculation of total heat flux (convection + radiation + conduction in fins) is fully compatible with that one for bare tube banks/bundles developed earlier. It is based on the method of radiative coefficients, too. However, the resulting value of heat flux must be corrected due to fin thicknesss and especially due to the fin radiative influence. For this purpose so called multiplicator of heat flux was introduced. The applicability of this method has been demonstrated a tubular fired heater on convective section. A developed Computer programbased on the method has also been used for an analysis of the influence of selected parameters to show the share of radiation on the total heat flux.
