The present invention generally relates to a cooling tower for a hybrid cooling system. The cooling tower may include a tower shell, a wet cooled segment arranged inside the tower shell, and a dry cooled segment arranged outside the tower shell. The wet cooled segment may include wet cooling cells arranged at a distance from the tower shell with fans arranged thereon for inducing upwards humid air exhaust flow. The dry cooled segment is disposed generally above the air intakes for the wet cells and includes air coolers arranged as vertical cooling deltas around the tower shell. The cooling deltas are equipped with louvers for controlling a cooling air inlet. The cooling tower further includes dry fans arranged in at least some of the inlet openings of the tower shell for inducing mechanical draft for the dry cooled segment.
The invention is a method for producing a mixture of powder or granular state material and liquid, in the course of which a first mixture is produced by conveying the powder or granular state material through an inlet hopper into an upper mixing space and by feeding the liquid into the upper mixing space, the first mixture is introduced into a lower mixing space through a conducting pipe connecting a bottom part of the upper mixing space and an upper part of a lower mixing space having a cylindrical space portion and a conical space portion, and a second mixture is produced by causing it to collide into a baffle member, the second mixture is discharged through the conical space portion arranged at the bottom part of the lower mixing space. By dividing the second mixture, a first mixture portion is discharged as a mixture material, a second mixture portion is re-circulated into the upper mixing space, and a third mixture portion is conveyed into the upper part of the lower mixing space. The ratio of the first mixture portion to the second mixture portion is chosen to a value between 1:1 and 1:4, the ratio of the first mixture portion to the third mixture portion is chosen to a value between 1:1 and 1:5, and in the lower mixing space the amount of the second mixture is adjusted so that the surface of the second mixture is within the cylindrical space portion of the lower mixing space and is spaced from the baffle member.
