    摘要： A method for operating a gas and steam turbine plant includes utilizing heat contained in an expanded working medium from a gas turbine to generate steam for a steam turbine connected into a water/steam circuit. The working medium for the gas turbine is generated by combustion of a fuel along with a supply of compressed air. In order to increase efficiency of the plant, the generated steam, before being introduced into the steam turbine, is superheated through the use of heat occurring during hydrogen/oxygen combustion. The plant includes a waste-heat steam generator which is located downstream of the gas turbine on the exhaust-gas side and in which a number of heating surfaces connected into the water/steam circuit of the steam turbine are disposed. A hydrogen/oxygen burner is connected into the water/steam circuit between the waste-heat steam generator and the steam turbine.

    摘要： The invention relates to a method for the direct thermochemical conversion of high molecular weight organic starting products into low molecular weight organic products that are liquid with a low viscosity at ambient temperature and can be combusted. Said method consists of the following steps: (1) the starting product, at least one reducing gas and slow-evaporating product fractions are provided in a reactor, (2) the provided starting material is rapidly heated to a reaction temperature, (3) said starting material is converted using the temperature, the reducing effect of the gas and autocatalytical effects of the product fractions in vaporous reaction products and reaction gas, (4) the reaction gas is separated by means of condensation by evacuating the condensed reaction products, said separated reaction gas comprising a mixture of hydrogen, methane and other hydrocarbons and carbon monoxide and carbon dioxide. Said claimed method is characterised by other additional steps: (5) the separated reaction gas is conditioned by (a) removing at least one part of the carbon dioxide or (b) reforming at least one part of the carbon dioxide and the methane and/or other hydrocarbons or one part of the methane and/or other hydrocarbons or (c) removing one part of the carbon dioxide and reforming in parallel at least one part of the carbon dioxide and at least one part of the methane and/or other hydrocarbons or (d) removing one part of the carbon dioxide and subsequently reforming at least one other part of the carbon dioxide and at least one part of the methane and/or other hydrocarbons or (e) reforming one part of the carbon dioxide and at least one part of the methane and/or other hydrocarbons and subsequently removing at least one part of the carbon dioxide and optionally, introducing hydrogen, said conditioning followed by (6) re-injecting the conditioned reaction gas into the reactor for simultaneously producing a hydrating, reducing and stripping effect for converting the starting material. According to the invention, the amount of active gas fractions and its part in the total flow of the reaction gas can be modified in an advantageous manner, thus increasing the effectiveness of the method and leading to an improvement of the target product quality and yield with total lower production costs. The invention also relates to a method for carrying out the claimed method.

    摘要： A repair lining for a heat exchanger tube includes a sleeve having ends. A tubular basic body is disposed in the sleeve and has ends protruding beyond the ends of the sleeve. One of the ends of the basic body has a top part being supported on the sleeve and the other of the ends of the basic body has a thread formed thereon. A nut is disposed on the thread for bracing the repair lining in the heat exchanger tube. At least one clamping ring is disposed on one of the ends of the basic body between the sleeve and the top part, and at least one clamping ring is disposed on the other of the ends of the basic body between the sleeve and the nut. The clamping rings have a conical shape in an initial relaxed condition being changed into a flattened shape with an enlarged diameter by relative motion between the basic body and the sleeve. A method for repairing a heat exchanger tube with a repair lining includes introducing a repair lining into the heat exchanger tube, and tightening the nut with a tool for axially enlarging the clamping rings and substantially fluid-tightly connecting the basic body to the heat exchanger tube.
