FIELD: technological processes; heating. n SUBSTANCE: used cloth nozzle (1) comprises vertical layers (11', 12') formed by wire cloth materials (11, 12) that make together wavy or corrugated flow channels (13). Flow of gas or steam flows along flow channels, and liquid flow flows on wire cloth. Flow channels of neighboring layers openly intersect. Angle between intersecting channels is approximately below 100°. At that cloth nozzle experiences relatively low liquid load. Wire cloth forms carrier for flow of liquid, which is mostly free from holes or other ruptures. Values for liquid load are accepted according to the following ratio: L/a < 10 l/m·hour. At that L is specific load per liquid volume unit per unit of nozzle cross section surface, and a is specific surface of wire cloth tension. Cross-channel nozzle (1) comprises at least one nozzle element (10, 10', 10"), and every nozzle element has distinguished lower edge zone (102), middle zone (100) and upper edge zone (101). n EFFECT: lower pressure loss in system without reduction of flow channels inclination. n 8 cl, 4 dwg |
