Abstract (en)
[origin: WO9509325A1] In order to avoid the inconvenience that results from a faulty heating of individual pipes (10) of a steam generator (2) with vertical pipes arranged in the combustion chamber, the mass flow density m in the pipes (10) is set below a predetermined maximum value (curve B) which depends on the inner diameter d of the used pipes. In order to avoid inadmissibly high pipe wall temperatures even at the proximity of a critical pressure of about 200 to 221 bars, the inner surface of each pipe (10) is further provided with a surface structure that causes a high turbulence and/or a longitudinal vortex in the flowing medium. The components of the flowing medium are thus intimately mixed so that a good heat transmission is achieved.
