Popis: The paper presents validation of innovative adaptation of modified plug flow (MPF) model to recognition of thermal behaviour of industrial system of low emission gas fuel burners operated in radiant chamber of vertical cylindrical fired heater placed in crude oil atmospheric distillation plant. The MPF model originally developed for calculation and identification of real distribution of heat flux along height (length) of combustion chamber burner testing facility of Institute of Process Engineering at Brno University of Technology is adapted and applied to situation of vertical cylindrical radiant chamber of fired heater in order to recognise a real thermal behaviour of actually operated low emission burner system and its influence on hardly operated fired heater characterized by high fouling rate of heated crude oil inside radiant tubes accompanied by significant deformations of radiant tubes. Results of adapted MPF model are confronted with results of fired heater heat flux operational measurements and with comparative results of CFD simulations and bears important observations concerning influence of thermal behaviour of installed burners system on fired heater operation.
