Originální abstrakt

Tubular fired heater in vertical cylindrical arrangement operated in crude oil atmospheric distillation unit is simulated numerically to analyse the circumference heat flux variation and distribution of thermal loading on the individual tubes. The complex numerical model describes flow, gas combustion and radiative heat transfer inside the radiation section of the fired heater. Special attention is focused on the degree of non-uniformity of circumferential distribution of heat flux on tube walls. Obtained results show that assumptions invoked in 1D design calculations of fired heaters are significantly underestimating heat flux variability.
