Fired heaters: validation of design parameters based on numerical modelling

Popis výsledku v původním jazyce

Fired heaters are used all over the World for refinery processes. Many of them are designed according the American Petroleum Institute Standard 560. Several facilities encounter significant deformation of tubes or other imperfection related to the tube wall heat load. This leads us to investigation of design parameters suggested by the API standard 560. The key design parameters are related to non-uniformity factors, which represent wall heat flux profile over the length and circumference of tube. Sincethe onsite investigation is almost impossible the numerical flow simulation is used. The present work reports parametric studies of tube deformations in a cylindrical fired heater (radially and tangentially deformed tubes). The results are reported in the form used by furnace designers, i.e. in terms of circumferential and longitudinal heat flux factor. This way, the work provides information on the effect that deformations of tubes during the lifetime of a furnace may have on heat flux
