  • Challenges of Cogeneration

    Publication

    - Year 2005

    Przedstawiono problemy skojarzonego wytwarzania ciepła i energii elektrycznej w Polsce. Omówiono układy technologiczne i problemy sprawności wytwarzania skojarzonego. podano przykłady problemów, które powinny być rozwiązane w nowych warunkach ekonomicznych zarówno w dziedzinie optymalizacji ekonomicznej jak i technologicznej.

  • Control of a vapour microturbine set in cogeneration applications

    Publication

    Systems with microturbines are implemented for local generation of heat and electricity. This paper presents the analysis of control concepts for a vapour microturbine set with a generator with permanent magnets, intended to work in small heat and power plants. Control system variants differed by the selection of controlled signals and set parameters. Possible ways of control were discussed and compared with experimentally determined...

  • Alternative cogeneration thermodynamic cycles for domestic ORC

    The Organic Flash Cycle (OFC) is suggested as a vapor power cycle that could potentially improve the efficiency of utilization of the heat source. Low and medium temperature finite thermal sources are considered in the cycle. Additionally the OFC’s aim is to reduce temperature difference during heat addition. The study examines 2 different fluids. Comparisons are drawn between the OFC and an optimized basic Organic Rankine Cycle...

  • Marine turbines: cogeneration and combined propulsion systems.

    Publication

    - Year 2004

    Omówiono główne aspekty kombinowanych siłowni okrętowych, zwracając szczególną uwagę na układy parowo-gazowe oraz skojarzone wytwarzanie pracy mechanicznej i ciepła. Przedstawiono perspektywy rozwoju tego napędu

  • Profitability criteria of partial cogeneration in nuclear power plant.

    In this paper, profitability criteria and calculation methodology of profitability conditions for partial cogeneration in nuclear power plant (NPP) was presented. Considered NPP supplies electricity to consumers through public power system, whereas heat is expected to be supplied to consumption regions via long-distance heat transport line. First proposed profitability criterion was total annual costs of electricity and heat delivered...
