AbstractAbstract
[en] Heat transformers are a promising technology for optimal exploitation of waste heat streams. The use of heat transformers is efficient for energetic, exergetic, and economic reasons. Heat transformers are environment-friendly, and reduce both thermal pollution and the pollution by greenhouse gases. The practical use of heat transformers is however still limited to the water/LiBr pair. The application of new media and the multistage heat transformer are promising new developments. (A.S.)

AbstractAbstract
[en] Small gas turbines in power range of several MWs are quite suitable for application in distributed generation as well as Community Energy Systems (CES). Humidification is an effective way to improve gas turbine performance, and steam injection is the most general and practically feasible method. This study intended to examine the effect of steam injection on the performance of several MW class gas turbines. A primary concern is given to the regenerative cycle gas turbine. The steam injection effect on the performance of a system without the regenerator (i.e. a simple cycle) is also examined. In addition, the influence of bypass of some of the exhaust gas on the performance of the gas turbine, especially the regenerative cycle gas turbine, is evaluated.

AbstractAbstract
[en] The 250 kWe SOFC/CHP system was designed as the first pre-commercial demonstration of Siemens Westinghouse Power Corporation's (SWPC) atmospheric-pressure SOFC technology. This integrated package combining fuel cell and heat recovery, was predicted to deliver electrical-generation efficiencies above 45% and total energy efficiency with heat recovery approaching 80%. SOFC technologies are widely heralded as the state-of-the art in stationary power generation. High electrical conversion efficiencies (up to a potential of 70% in pressurized hybrid units), very low emissions, virtually solid state (few moving parts), and high exhaust-heat recovery make SOFCs very desirable as distributed generation technologies. With their tubular technology, SWPC is recognized as the world leader in SOFC stationary systems designed for distributed generation applications. (author)

AbstractAbstract
[en] Microfluidic devices have become more and more popular over the last decades. Cooling is a topic where microstructures offer significant advantages compared to conventional techniques due the much higher possible surface to volume ratios and short heat transfer lengths. By evaporating of a fluid in microchannels, compact, fast and powerful cooling devices become possible. Experimental results for different designs of microstructured evaporators are presented here. They have been obtained either using water as evaporating coolant or the refrigerant R134a (Tetrafluoroethane). A new microstructured evaporator design consisting of bended microchannels instead of straight channels for a better performance is shown and compared to previous results for the evaporation of R134a in straight microchannels.

AbstractAbstract
[en] EN12952-4 provides a method for calculation of in-service low cycle fatigue damage. The procedure describes the calculation of low cycle fatigue damage of boiler components during operation. Temperature, pressure, temperature differences, strain, etc. are considered in the determination of actual damage level. The EN12952-4 also includes creep calculation and creep-fatigue combined calculation, but this part, essential for Remaining Life Assessment, it is not in the scope of this paper. The European standard provides also calculation examples, even if only by computer data logging system it is possible to apply the procedure. Fatigue calculation, as well as creep and creep-fatigue calculation, is essential for modern HRSG plants, where the changing of operational conditions is quite often applied.

AbstractAbstract
[en] A larger Nuclear Power Generation and Non Nuclear Power Generation are shipped to the job sites in various stages of fabrication and subassembly. Welding and welding related processes are central to Power Generation component fabrication and assembly in the site. This papers presents some results of the investigation that was carried out to examine the welding results of the site construction of Heat Recovery Steam Generator Piping of Tanjung Priok Gas Fired Power Plant Extension Project (740 MW) using the Radiography Test Method based on the ASME Standard. From this investigation it could be concluded that there was no crack founded in the selected specimens of the piping. The rejectable Incomplete Penetration was found in the Hot Reheat Steam Piping HRSG1. Some Porosities and Slag Inclusion are rejected because their size and length are longer than acceptable value limits, therefore should be repaired. However some of the results are accepted and no need to be repaired. The rejected Worm Holes is found on IP Super Heater Inlet Piping of HRSG1 whereas the undercut occurred on HP Steam Drum of HRSG.
