Abstract (en)

[origin: EP0853214A2] A steam superheating method involves directing some or all of the pressure energy of the steam (v) into a rotation round an axis, and converting it into an overlaid axial flow towards the rotary axis. The rotary speed of the steam in the direction of the rotation axis is increased by a reduction in the flow cross section, and condensation and remaining steam are developed. Before the flow cross section is reduced, the condensation is separated from the remaining steam, and evacuated radially outwards. The remaining steam is fed onwards, its rotation speed is reduced, and the remaining steam is superheated and converted to hot steam. Also claimed is a device with a chamber (2) extending on the line of a rotation axis. The entry zone (4) at least partially converts the pressure energy of the steam into kinetic energy at the steam, and separates any condensation from the remaining steam. The kinetic energy is increased in a transit zone (6) against the entry zone, with a smaller cross section surface. The outlet zone, after the transit, reduces the kinetic energy of the remaining steam and converts it into hot steam, using a larger cross section surface than at the transit zone. The outlet zone has an outlet (20) for the hot steam and an outlet (22) for the condensation, at a radial gap from the rotation axis.
