Abstract
(DE)
Bei einem Durchlaufdampferzeuger (2) mit einer Brennkammer (4), dessen vertikal verlaufende und auf ihrer Innenseite eine Oberflächenstruktur (26) aufweisende Rohre (12) von einem Strömungsmedium (S) von unten nach oben durchströmbar sind, entspricht eine besonders günstige Massenstromdichte m in den Rohren (12) bei derjenigen Last, bei der in den Rohren (12) kritischer Druck (pkrit) herrscht, erfindungsgemäß der Beziehung (7).
(EN)
The invention concerns a continuous steam generator (2) having a combustion chamber (4) with vertically extending pipes (12) which have a surface structure (26) on the interior. A flow medium (S) flows upwards through the pipes (12). According to the invention, a particularly advantageous mass flow density m in the pipes (12), at a load at which critical pressure (pcrit) prevails therein, corresponds, according to the invention, to the relation (7).
(FR)
L'invention concerne un générateur de vapeur continu (2) comportant une chambre de combustion (4) dont les tuyaux (12) verticaux ont une face intérieure présentant une structure superficielle (26) et peuvent être traversés de bas en haut par une substance en écoulement (S). Dans ce générateur de vapeur continu (2), une densité de flux massique m particulièrement avantageuse dans les tuyaux (12), pour une charge créant une pression critique (pcrit.) dans les tuyaux (12), correspond selon l'invention à la relation (7).
