“…Deaerator divides condensate/feed water heating system in low pressure and high pressure part [25]. In steam plants in general, not only the marine steam propulsion plant, deaerator has a dual function -first is direct condensate heating [26], while the second is the removal of dissolved gases from the condensate with the aim of pipeline corrosion reduction [27]. Between deaerator and steam generators in the marine steam propulsion plant is mounted Desuperheater (DES) and one or more High Pressure Heaters (HPH) [28].…”

This paper presents energy analysis of entire marine main propulsion steam turbine and both of its cylinders at three different loads. Marine steam propulsion plant in which main turbine operates is described in detail. Measured data from real exploitation at each required turbine operating point enables calculation of energy losses and efficiencies. Real developed power distribution between both turbine cylinders is not the same at all observed loads. Energy losses and efficiencies of main turbine cylinders and entire main steam turbine increases during the increase in turbine load. An increase in turbine load resulted with in a sharp increase in energy efficiency of HPC (High Pressure Cylinder) from 51.01 % to 74.13 %, while the increase in energy efficiency of LPC (Low Pressure Cylinder) is not as sharp (from 73.88 % to 78.50 %). The change in energy efficiency of the entire main steam turbine during the load increase (from 65.54 % to 79.45 %) is mostly influenced by a change in energy efficiency of HPC. Energy loss and real developed power ratio is reversely proportional to energy efficiencies and losses of both steam turbine cylinders and the entire turbine. Sažetak Ovaj članak prikazuje energijsku analizu čitave glavne propulzijske parne turbine i oba njezina kućišta pri trima različitim opterećenjima. Opisuje se podrobno, brodsko parno propulzijsko postrojenje u kojemu radi glavna turbina. Izmjereni podatci stvarne eksploatacije za svaku zahtijevanu radnu točka turbine omogućavaju izračun energijskih gubitaka i učinkovitosti. Stvaran raspored distribucije snage između oba kućišta turbine nije isti na svim promatranim opterećenjima. Energijski gubici i učinkovitosti turbinskih kućišta i cijele glavne turbine, povećavaju se za vrijeme porasta opterećenja turbine. Povećanje opterećenja turbine rezultira naglim rastom energijske učinkovitosti HPC (High Pressure Cylinder = kućište visokoga tlaka) od 51.01 % do 74.13 % dok povećanje energijske učinkovitosti LPC (Low Pressure Cylinder = kućište niskoga tlaka) nije tako naglo (od 73.88 % do 78.50 %). Promjena energijske učinkovitosti cijele glavne parne turbine, za vrijeme povećanja opterećenja (od 65.54 % do 79.45 %), najviše je pod utjecajem promjene energijske učinkovitosti HPC. Gubitak energije i stvarni omjer razvijene snage obrnuto je proporcionalan energijskim učinkovitostima i gubicima za oba kućišta i cijelu parnu turbinu.

“…It was also highlighted that a year round operation is necessary to improve the economic feasibility of the hybridized plant. Burin et al[105] continued the analysis and compared the plant with a parabolic trough solar field to the plants with a linear Fresnel solar field and a solar tower. The solar tower based plant was found to result in the best levelized cost of electricity among the three alternatives.Zhang et al [106] analysed a solar-biomass hybrid trigeneration plant concept for China for the production of electricity, hot water, and chilled water.…”

“…Moreover, the highest solar to electricity efficiency was achieved when the highest feedwater heater of the power plant was substituted with a solar farm. Burin et al assessed the replacement of conventional feedwater heaters with parabolic solar trough collectors and studied the system through a thermo‐economic analysis. The authors' main target was to provide an efficient economic condition when solar energy is unavailable.…”

Summary In this study, a conventional steam power plant with two regenerative boilers is considered, and one of its boilers is replaced with parabolic solar dish collectors and storing the produced thermal energy by the phase change material (PCM) in a storage tank. The results show the necessity of the existence of an auxiliary fired‐gas boiler to provide constant load during the whole 24 hours. The performance of the proposed hybridized system is evaluated through energy and exergy analyses. It was demonstrated that substituting solar collectors with one of the boilers marginally lowers the energy efficiency but increases the exergy efficiency of the whole power plant up to 41.76%. Moreover, it is found out that this hybridization decreases the total irreversibility of the power plant in comparison with the base case, from 51.1 to 47.2 MW. The parametric analysis states that raising the mass flow rate of the heat transfer fluid in the solar collectors not only enhances the system performance but also increases the volume of the PCM tank.
