Abstract: The subject of the invention is a process for the hydrogenation of hydrogen carbonate in an aqueous reaction system, where the process ensures that the hydrogen carbonate, hydrogen and catalyst come into contact with each other while carbon dioxide is present in the gas space. In this phase of the process, formate is produced. The subject of the invention is also a process for the catalytic decomposition of formate in an aqueous reaction system and the hydrogenation of hydrogen carbonate produced in the same reaction system according to the invention, where the reactants and the reaction products are formed in a reversible reaction cycle using the reaction system according to the invention, and this reaction cycle is repeated in the required number of times. In the mentioned formate mg decomposition process, the formate and the catalyst come into contact, so that hydrogen gas and hydrogen carbonate free of COX by-products are produced as the product of the reaction.

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.

Abstract: A balancing device is provided that is able to balance a rotor of an electrical machine. The machine includes a mounted rotor in a central bore of a stator and coaxially thereto. Between the rotor and the stator there is an air gap. The rotor preferably comprises a plurality of axially extending ferromagnetic teeth and non-magnetic wedges being arranged alternately around the circumference of the surface of the rotor. The teeth and/or the wedges preferably include balancing openings for balancing weights. The balancing device includes a mounting device and/or a locking device and/or a confirmation device. The device has a radial height that is smaller than the minimal clearance of the air gap and an axial extension such that it can be inserted into the air gap. With such a device it is possible to balance a rotor in an efficient way, when it is located in the bore of the stator.

Abstract: An air-cooled condenser includes an upper header for distributing a vaporous medium to be condensed, a lower header for collecting condensate, spaced finned tubes with outer fins, the finned tubes being connected in parallel between the upper header and the lower header and cooled by a cooling air flow, means for draining the condensate form the lower header and extraction means for removing non-condensible gases from the condenser. The lower header is also used for distributing the vaporous medium to the finned tubes, so that the vaporous medium id fed into the finned tubes through both the upper and lower headers, and the extraction means are connected to each of the finned tubes at its portion facing the cooling air flow.

Abstract: An air-cooled condenser comprising a distributing chamber for distributing a vaporous medium to be condensed, a condensate collecting chamber and finned tubes with fins on air side, said finned tubes being connected in parallel between the distributing chamber and the condensate collecting chamber, where each of the finned tubes comprises two parallel essentially flat side walls and exterior closings connecting the side walls, in the finned tubes there are longitudinal separation walls connected to the side walls and dividing the inner space of the finned tubes into longitudinal parallel channels, and in the separation walls there are breakthroughs and closure elements for allowing the flow of the medium between neighboring channels.

Abstract: A jet condenser of the type comprising a water chamber in a mixing chamber (24) and an after-cooler (52), wherein the water chamber is subdivided in a narrower upper water chamber portion (38a) and a broader lower water chamber portion (39b). The after-cooler (52) is fixed at the junction (66) of both water chamber portions (38a, 38b). Cooling water is injected into the mixing chamber (24) by nozzles (40) of the upper water chamber portion (38a) where it flows in vertical direction. By the reduced width of the upper water chamber portion (38a) flow resistance of steam flow in the mixing chamber (24) and, thereby, undesired subcooling is substantially diminished. (FIG. 3).

Abstract: A heat exchange pipe for heat transfer between a medium in the pipe (1) and another medium outside the pipe (1) including baffle elements (3) for deflecting a layer of the first medium in the pipe (1). According to the improvement in this invention, each baffle element (3) has two kinds of deflecting channels, an inlet opening of the first kind of which is in a well defined first portion of a cross-section of the pipe (1) and its outlet is in a well defined second portion of the cross-section, and an inlet opening of the second kind of deflecting channels is in the second portion and its outlet is in the first portion of the cross-section.
