Abstract: This invention relates to gas-steam power plants with the closed contour of circulation of gas and can be used at nuclear power plants. They heat up gas in a heater (1), then direct heated gas into gas turbine (2) where transform a part of heat of this gas into mechanical work, then transfer part of heat of this gas to liquid in steam heater (3), vaporizer (4) and heater of a liquid (5) connected in series on a way of a liquid and direct the steam received on an outlet of steam heater (3) into steam turbine (12). They compress the cooled in heat exchangers (3), (4) and (5) gas by multistage compressor (6) and return gas into heater (1) for repeated heating. In additional heat exchangers (7) in parallel with vaporizer (4) on a way of a liquid they additionally vaporize a liquid by heat of gas, heated at stages of the multistage compressor (6). After vaporizing of a liquid they additionally heat up received steam in the steam heater (3), installed by the first on a way of the gas after gas turbine (2).

Abstract: This invention relates to systems for division of the materials mixed in the fluid medium being filtered, for example, for purification of water at power stations. Multisectional filtering device for division of the materials mixed in the fluid medium being filtered contains sections being connected to each other with executed in each section bringing and removing hollows and a sorbent located in sections, moreover sections have the identical sizes and are executed everyone in the form of a prism with the six-angle basis and with walls being parallel and identical in pairs, the sections' bases form the device's two butts' walls being parallel to each other, sections adjoin to each other so that the lateral wall separating two neighbour sections is general for them, and all walls are rigidly connected among themselves.

Abstract: The group of inventions relates to nuclear techniques and to power industry. The nuclear power plant contains a nuclear reactor (1) cooled by liquid metal, for example lead. Heated-up liquid metal is cooling in heat exchanger <<liquid metal-gas>> (3). This heat exchanger is embodied as not-mixing heat exchanger. The pump (2) moves cooled liquid metal through the filters into the reactor (1). The compressor (4) moves gas through heat exchanger <<liquid metal-gas>> (3) into gas turbines (8, 9, 10, 22, 23, 24). After gas turbines this gas vaporizes and overheats the water in heat exchangers <<gas-water>> (5, 6, 7) and moves back to compressor (3). Produced steam moves the steam turbines (12, 13), condenses into the water by means of condenser (15) and circulation pump (16) and then is moved by the pumps (17, 20) back to heat exchangers <<gas-water>> (5, 6, 7).
