Abstract: The invention is a cooling system comprising adjacent cooling deltas (21, 31) being cooled by a cooling air and being arranged along a path (20, 30). The cooling system is characterized by comprising cooling deltas (21, 31) arranged in groups (22), the cooling deltas of a group (22) being arranged essentially in the same orientation and define an essentially straight path-section, wherein the path-sections of adjacent groups (22) form a zigzagged path (20, 30).

Abstract: The invention is a hybrid condenser having a direct contact condenser segment (9) and a surface condenser segment (10) arranged in a common condensation space. The hybrid condenser includes a surface condenser segment (10) arranged downstream the direct contact condenser segment (9) in the direction of steam flow or below the direct contact condenser segment (9), and a water guiding element (17) ensuring that the cooling water and condensate mixture generated in the direct contact condenser segment (9) flows downward avoiding the surface condenser segment (10).

Abstract: 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.

Abstract: 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.

Abstract: The invention is a cooling delta for cooling liquids, gases or vapours, said cooling delta comprising cooling panels arranged at an angle relative to one another, in which cooling panels cooling tubes are arranged, the cooling tubes extend horizontally or substantially horizontally, and the cooling delta further comprising a first media flow header being connected to the cooling tubes at a junction of the cooling panels, and providing a flow communication space for the cooling tubes, and second media flow headers being connected to opposite ends of the cooling panels with respect to the first media flow header, and providing a flow communication space for the cooling tubes.
