Opis:
The use of new technologies in modern industry improves productivity but induces complexity in the industrial system. This complexity makes it vulnerable to faults, which requires significant expense in terms of safety, reliability and availability. Indeed, a diagnostic operation is essential for the operational safety and availability of these industrial systems. This diagnostic operation is based on two important functions which are the detection and localization of anomalies, which consists to verifying the consistency of the data taken in real time from the installation with a reliable model, to ensure the good performance of the monitoring system. Hence, the diagnosis of gas turbines is a main component for making maintenance decisions for this type of machine. In this paper, the faults detection approach based on fuzzy logic is applied for the vibrations monitoring of a gas turbine, in order to monitor their operating state by including the detection and occurrence of vibration faults, thus using determined fault indicators based on the input/output variables of the examined gas turbine. In this work, the investigation results of fuzzy fault detection approach applied on gas turbine vibration are presented, based on the actual data recorded in the different gas turbine operating modes. However, analysis of the defect detection results was performed in order to determine the influence of these vibration defects on the deferent operating modes of the examined machine. This makes it possible to find the causes of failures and then to deduce the actions to follow the operational safety of the examined turbine.

Opis:
This article presents a literature review about the physical analysis of the loss models, which are used in offdesign procedure for high-pressure turbines. A high-pressure turbine is designed to have maximum performance at design point. However, engines are operating in different conditions, and the comprehension of off-design conditions is very important. The loss mechanisms are very complex and predictions considering empirical methods are a good approach to have preliminary results. Based on these results, different researches have proposed theories about the loss mechanisms, and over the time, these models have been modified to describe better the phenomena involved between blades and flow. Once the physical mechanisms behind the loss models are known, it is possible to compare them and understand the reason why the results given for some methods present a higher agreement to experimental or numerical data. In this framework, 2D numerical simulations of the flow around the blades of an axial high pressure turbine with different off design conditions have been realized, by using ANSYS FLUENT® code, to show the losses described by some of these models. Using these simulations a loss model has been selected and implemented in Matlab® to compare its results with the experimental data found in literature.

Opis:
The article compares the results of the measurements performed in the aerodynamic tunnel owned by the Czestochowa University of Technology and the numerical simulation done using the code FLUENT for a plane cascade of N3-60 profiles. The comparison study aims at assessing differences between the exit angles measured experimentally and those obtained from numerical calculations. Variable parameters in the measurements and the calculations were the relative pitch and the profile stagger angle. The measurements were performed in the flow of air. The same medium and having the same inlet parameters was assumed in the calculations. The calculations were performed in two dimensions for the compressible flow. The k-ĺ RNG turbulence model was used to complete the equation system. Comparing the measured and calculated results provides opportunities for assessing the range of differences between the experiment and the simulation. The obtained results and formulated conclusions will find the application not only in the power industry, but also in the shipbuilding industry for analysing the operation of steam and gas turbines used as main and auxiliary propulsion systems on both merchant vessels and battle ships.

deviation angle
Opis:
In the article, a set of deviation angle models, which are used to predict the off-design performance high-pressure turbines, has been presented, basing on a literature study. The deviation angle is a deviation between the actual flow angle and the blade inclination angle. It is an essential parameter in turbine performance evaluation. This angle shall be obtained accurately in 1-D design and evaluation, so as to ensure the validity of blade profiling and calculation results. If deviation angle is ignored, the turbine will produce a lower change of tangential velocity, and consequently a lower torque, output work and enthalpy drop than intended by the designer. For this reason, the deviation angle model needs to be established. There exist a number of different deviation models, resulting in varying degrees of flow deviation when applied. In the article, correlations for gas outlet angle, dependent on the Mach number at outlet and determined by the blade loading towards the trailing edge has been presented. The main difficulty in establishing the deviation model is a continuity in defining the angle for all speed ranges (both subcritical and supercritical). Each of the models presented in the article deals with this problem in a different way. A few deviation models, briefly discussed in the article, are based on experimental data and one is based on analytical approach.

Opis:
The typical combined heat and power plants requires the introduction of additional heating medium. The alternative solution is the direct integration of the exhaust gases from heat engine. The high temperature, surplus oxygen and low water content of the GTs exhaust gases enabled the successful integration at industrial scale as: preheated combustion air for industrial furnaces, heat source for drying and for absorption chillers. The article comprises the reference list for direct exhaust gas integration of GTs produced by GE, the processes overview, GTs selection criteria, as well as the review of documented GTs applications in process industry focusing on technical and economic considerations. The described solutions allowed to reduce the specific energy consumption in the range from 7 to 20% or the costs of energy consumption by 15-30%. The overall efficiency of cogeneration plant above 90% was achieved. The preliminary assessment of potential applications for GTs produced by GE with TEG integration in Polish process industry is done.

Carbon dioxide is considered as one of the major contenders when the question of greenhouse effect arises. So for any industry or power plant it is of utmost importance to follow certain increasingly stringent environment protection rules and laws. So it is significant to keep eye on any possible methods to reduce carbon dioxide emissions in an efficient way. This paper reviews the available literature so as to try to provide an insight of the possibility of using Molten Carbonate Fuel Cells (MCFCs) as the carbon capturing and segregating devices and the various factors that affect the performance of MCFCs during the process of CO2 capture.

Opis:
The paper concerns a propulsion system of merchant ships intended for sailing in the Baltic Sea zone. Such system is to satisfy the ecological requirements determined by relevant international conventions for special zones to which the Baltic Sea also belongs. The paper draws attention to gas turbine used as a prime mover for such ships, because it satisfies the ecological requirements and has also other advantages. Application of gas turbine for ship powering does not require exhaust gas to be purified, however it requires fuel oils of a low sulphur content to be used. If the ecological rules impose the using of the fuel oils of similar quality for diesel engines then gas turbine propulsion system will be comparable - also economically (regarding specific fuel oil consumption cost) - with that of diesel engine. It would be even more favourable in a combine gas turbine /steam turbine system, especially at compound production of electric and heat energy (i.e. COGES systems). In the Baltic Sea zone gas turbines willfind application to powering a. o. such ships as : fast car-passenger ferries, fast cargo ships, special vehicles (hydrofoils, hovercraft, motor yachts).

Opis:
Gas carried on LNG carriers is liquefaction gas at ambient pressure and temperature minus 163oC degree is subject to boil-off and causing increase in pressure. This phenomenon makes danger of explosion. The simplest possibility to circumvent the foresaid event is to release-liquefied gas to atmosphere. However, the mentioned way causes losses of cargo and air pollution. There is an option to re-condensate gas again nevertheless to do it extra energy is required. Method that is more rational is to use boil-off fuel gas as propulsion energy in diesel engines, gas and steam turbines. This paper describes exploitation costing of main propulsion on LNG carriers trying to find out the best solution. There are presented fuel gas supply system as well various type of engine driven by fuel gas. Moreover, author presents further design development of LNG carriers. Possibilities of cost reduction related to boil-off fuel gas, the Moss RS standard setup for gas reliquefaction system, example of dual fuel diesel engines and electric propulsion, basic design concept for two compressor units 100% type 6LP250-5S1, diagram of COGES system, thermal efficiencies for the different propulsion options, technical data of some present dual-fuel engines, as well two-stroke propulsion recommendations for LNG carriers are illustrated in the paper.

Opis:
Vibration diagnostic tests of marine gas turbine engines are performed as a research of on-line and off-line types. On-line systems generally monitored one or two vibration symptoms, which asses the limited and/or the critical values of parameters and they, potentially, can warn and/or shutdown engines. Off-line Systems are usually used for vibration analysis during non-steady state of work. The paper presents a new method of vibration diagnostics of rotor bearing system of gas turbine systems. The study assumes implementation of characteristics of vibration signals during the shut-down process of the rotor. The shut-down process is non-stationary so the studies used the order tracking procedure. Identified orders constitute individual characteristics as a function of changes of the rotational speed and shut-down process time. These allow the observation of changes in the support rigidity of the rotor in the frequency domain and change the bearing resistance torque as a function of changing time of the shut-down process. The resulting characteristics are as reference fingerprints for each of the rotors. Changes in the characteristics of the primary evidence of the processes of wear. Changes in the stiffness of rotor supports make change the amplitude of orders and frequency of the resonance signals observed in the frequency domain - decreasing rotational speed. The bearing wear results in changes in the shut-down time between successive intervals of characteristic rotational speed and the total shut-down time.

Vibration tests of marine gas turbine engines are performed as researches on-line and off-line types. The paper presents analyses of both methods. Results of tests were received on three types of gas turbine engines operated in the COGAG type propulsion systems. The application of periodical diagnostic procedures or on-line monitoring systems makes it possible to operate ship propulsion systems in accordance with their current technical state. In the case of ship gas turbines the hourly period of scheduled maintenance or repair surveys is presently the criterion for maintenance time determination. The Finite Element Analysis (FEA) is used for confirmation actual technical state. FEA are used successfully for a wide range of problems and it may also be used for the modelling and analysis of rotor system. Presently, the diagnostics team uses FEA and the modelling of rotordynamics in conjunction with vibration analysis for detection and identification of unbalancing. Main goal of researches was qualified of helpfulness and unequivocally results received by methods of synchronous measurement, order tracking and auto tracking. All vibration symptoms were chosen from the methodology of the diagnosing gas turbine engines operated in the Polish Navy, called BDS (Base Diagnosing System). This element of BDS is accepted and used in all ships of Polish Navy, which are powered by the COGAG power plant. Second purpose of researches was estimation of the possibility of implementation presented methods of vibration analyses of gas turbine engines fornew, modern on-line monitoring system. The proposed diagnostics method makes it possible to determine the limiting value of vibration symptoms witch, if exceeded, indicates the inadmissible axis slope value between rotated machines of gas turbine engine and, more-over, it provides an unambiguous relationship between the value of symptom of rotors unbalance and the rotors rotational speed.

Precision casting is currently motivated by high demand especially for castings for the aerospace, automotive and gas turbine industries. High demands on precision of this parts pressure foundries to search for the new tools which can help them to improve the production. One of these tools is the numerical simulation of injection process, whereas such software especially for investment casting wax injection, process does not exist yet and for this case must be the existing software, for alloys or plastic, modified. This paper focuses on the use of numerical simulations to predict the behavior of injected models of gas turbine blades segments. The properties of wax mixtures, which were imported into the Cadmould simulation software as a material model, were found. The results of the simulations were verified using the results of 3D scanning measurements of wax models. As a supporting technology for verifying the results was used the Infrared Thermography.
