<p>The invention relates to a water distribution system in a gasification reactor for carrying out a slag-forming entrained flow process, wherein in order to form a water screen as a water distribution system a concentric annular distributor is provided in conjunction with an axially symmetrical deflecting surface having a concavely curved cross-section, wherein the annular distributor has at least one water intake and the annular distributor has openings that are suitably designed for water to be discharged in the form of jet. The jets from the openings are directed onto the inside of the concavely curved deflecting surface, and in the direction of the jets from the openings the planar orientation of the concavely curved surface is configured such that the jet direction and the tangential plane of the surface at the point of impingement of the jet are oriented at an acute angle between 0 and 45 degrees toward one another, and in cross-section the deflecting surface is curved to such an extent that it has a deflection angle of more than 60 degrees. The water is conducted under pressure into an annular distributor, through which it flows quickly until it exits from the annular distributor through openings, wherein as the water exits each opening it forms a respective water jet which impinges on a deflecting surface, as each water jet slides along the deflecting surface it is fanned out and combines with the water jet from the respective adjacent opening to form a closed film of water, wherein after said closed film of water has left the deflecting surface, it is conducted downward into the interior of the reactor.</p> |
