Abstract

a presente invenção provê aletas espessas na superfície de bobinas ou tubos em um forno de craqueamento a vapor. as aletas têm uma espessura em sua base de 1/4 a 3/4 do raio do tubo de forno. as aletas têm ranhuras ou protuberâncias em não menos do que cerca de 10% de uma superfície principal. as aletas ajudam a aumentar o calor radiante absorvido pelo tubo a partir das paredes e gases de combustão no forno.
