Abstract

L'invention porte sur un générateur de vapeur à calandre dans lequel une série de tiges ayant un diamètre sensiblement égal à celui des tubes d'échange de chaleur dans le faisceau de tubes est placée de chaque côté de la voie entre tubes pour amortir l'écoulement dans la voie entre tubes provenant des tubes d'échange de chaleur, afin d'atténuer les forces turbulentes agissant sur les premières rangées des tubes d'échange de chaleur adjacentes à la voie entre tubes.
