Opis:
Performance management is one of the most significant strategies in promoting the efficiency of organizations and is highly sensitive. It is important to check the efficiency of combined cycle power plants because of their major contribution to power generation and air pollution. This study was conducted to evaluate the economic and environmental efficiency of Combined Cycle Power Plants (CCPPs). The inputs and outputs required to evaluate the performance of the power plants were determined according to expert opinions. Then, the 7-year statistics and information of the Qom, Neishabour, Shahid Rajaee, Yazd and Kerman power plants were collected as the desired CCPPs in Iran. The Window Data Envelopment Analysis (WDEA) method was used for evaluating the efficiency of the power plants. The 3-year window length showed that most of the power plants were efficient. Only the Rajaee, Neishabour and Yazd power plants were ineffective in some years. The mean efficiency of the power plants in the 4-year window length showed that the plants were efficient from 2008 to 2010.

Opis:
The paper presents a modified algorithm for choosing the optimal coefficient of the share of cogeneration in district heating systems taking into account additional benefits concerning the promotion of highefficiency cogeneration and biomass cofiring. The optimal coefficient of the share of cogeneration depends first of all on the share of the heat required for preparing the hot tap water. The final result of investigations is an empirical equation describing the influence of the ratio of the heat flux for the production of hot tap water to the maximum flux for space heating and ventilation, as well as the share of chemical energy of biomass in the fuel mixture on the optimal value of the share of cogeneration in district heating systems. The approach presented in the paper may be applied both in back-pressure combined heat and power (CHP) plants and in extraction-condensing CHP plants.

Opis:
Diverse forms of environmental pollution arise with the introduction of materials or energy that exert adverse effects on human health, climate patterns, ecosystems, and beyond. Rigorous emission regulations for gases resulting from fuel combustion are being enforced by the European Union and the International Maritime Organization (IMO), directed at maritime sectors to mitigate emissions of SOx, NOx, and CO2. The IMO envisions the realisation of its 2050 targets through a suite of strategies encompassing deliberate reductions in vessel speed, enhanced ship operations, improved propulsion systems, and a transition towards low and zero-emission fuels such as LNG, methanol, hydrogen, and ammonia. While the majority of vessels currently depend on heavy fuel or low-sulphur fuel oil, novel designs integrating alternative fuels are gaining prominence. Technologies like exhaust gas purification systems, LNG, and methanol are being embraced to achieve minimised emissions. This study introduces the concept of a high-power combined ship system, composed of a primary main engine, a diesel engine, and a steam turbine system, harnessing the energy contained within the flue gases of the main combustion engine. Assumptions, constraints for calculations, and a thermodynamic evaluation of the combined cycle are outlined. Additionally, the study scrutinises the utilisation of alternative fuels for ship propulsion and their potential to curtail exhaust emissions, with a specific focus on reducing CO2 output.

The paper discusses the use of fossil fuels and the process of their extraction in Poland. Hard coal used on a daily basis in one of the Polish combined heat and power plants was described, followed by monthly measurements of coal parameters. Daily and total analyzes of the obtained measurement results of hard coal were carried out in accordance with the applicable standards. The differences in the values of coal from the same source but imported at different time intervals are shown, which result from the weather conditions and the method of hard coal storage. Negative correlations occurred between ash content and calorific value, heat of combustion and volatile matter, as detailed in the work conclusions.

Opis:
The reduction of greenhouse gas emissions is a relevant challenge for a sustainable development. Waste heat could be used to produce hot water by using a recovery system. This article studies the availability of a combined heat and power systems (CHP) in extreme area (Antarctic) through the integration of a waste heat recovery system with a diesel generator to produce hot water. The reliability and availability principles are incorporated to explore how the profile of hot water consumption and the hot water storage tank size affect system availability. Different combined heat and power systems are thus classified, and their availability indexes modelled by adopting the continuous Markov approach and the state space model. The results indicate that the CHP systems availability is strongly influenced by the daily hot water demand profile. As a useful recommendation, one of the considerations for increasing availability, reducing costs and greenhouse gas emissions with the CHP system is to include a hot water tank in the analysis.

Opis:
Efficiency and electrical power output of combined cycle power plants vary according to the ambient conditions. The amount of these variations greatly affects electricity production, fuel consumption, and plant incomes. Obviously, many world countries have a wide range of climatic conditions, which impact the performance of power plants. In this paper, a thermodynamic analysis of an operating power plant located in Jordan is performed with actual operating data acquired from the power plant control unit. The analysis is performed by using first and second laws of thermodynamics. Energy and exergy efficiencies of each component of the power plant system are calculated and the effect of ambient temperature on the components performance is studied. The effects of gas turbine pressure ratio, gas turbine inlet temperature, load and ambient conditions on the combined cycle efficiency, power outputs and exergy destruction are investigated. Energy and exergy efficiencies of the combined cycle power plant are found as 45.29%, and 42.73% respectively when the ambient temperature is 34°C. Furthermore, it is found that the combustion chamber has the largest exergy destruction rate among the system components. The results showed that 73% of the total exergy destruction occurs in the combustion chamber when the ambient temperature is 34°C. Moreover, the results show that the second major exergy loss is in HRSC. The results show that the energy and exergy efficiency of the combined cycle power plant decreases as the ambient temperature increases. According to the calculation results, improvement and modification suggestions are presented.

The paper presents the concept of repowering in existing power plant. Among technologies for existing steam power plants, the hot windbox repowering is the fastest way to respond to the energy demand, improve efficiency and reduce the pollutants emissions. Thermodynamic analysis of power plant model with fossil boiler before and after hot windbox repowering, has been investigated using commercial software. The purpose of this work is to understand and analyze the effect of hot windbox repowering on 387 MW fossil fuel power plant as well as the effect of additional heat exchangers, which have been installed parallel with regeneration system to use the heat of boiler exhaust gases. In this way, after repowering the summary power of power plant in base load is 615 MW, which has been reached adding gas turbine (176.9 MW). To analyze the model, calculations were performed in 3 stages: 1) calculation and comparison of the thermodynamic parameters as well as carbon dioxide emissions of power plant model before and after repowering, 2) analysis of the optimal value of feed water mass flow through heat exchangers installed after economizer, 3) calculation of thermodynamic parameters in values 100%, 90%, 80% and 75% of fossil boiler heat loads.

The primary scientific objective of the Project was to establish, compare and analyze the actual values of basic technical, operational and economic parameters for different CHP (Combined Heat and Power) sets driven by gas piston engines, operated in Poland. An analysis of the techniques of fuel gas utilization in piston engine-driven cogeneration sets, being currently used (and also likely to be used in the future), finding their application in combined energy management, has been made within the Project, and a review of the operational conditions of a dozen or so CHP sets operated in Poland, fed by biogas, mine gas from hard coal mine demethanization has been carried out. The results of this analysis have been included in the present monograph which, in addition to the review of the conditions of CHP set operation, provides conclusions that have also utility importance, and therefore can well be useful in making the optimal design of a combined energy system consisting of combustion heat- and power-generating sets.

Opis:
The paper describes a combined cycle power plant with carbon capture installation in a post-combustion technology. Carbon dioxide is separated from flue gas by using a chemical absorption method with monoethanolamine (MEA) as a sorbent. Separated carbon dioxide is compressed in order to prepare for transportation to the storage place. This paper identifies the electric efficiencies and other characteristic parameters of power plants before and after implementation of CO2 capture installation, as well as the power plant efficiency drop, and the improvement of ecological characteristics related to the implementation of this installation. The implementation of the installation described herein is associated with the efficiency loss caused by the auxiliary power for additional installations. The CO2 separation installation is powered by heat energy required for reclaiming the sorbent. This energy is taken in the form of steam extracted from the steam cycle, thus reducing the steam turbine power output, while the CO2 compression installation is powered by electric energy.

Opis:
Evaluation of thermodynamic efficiency of a power plant is usually performed using the method of so-called thermal diagnostics, based on energy balancing. Energetic analysis is however suitable only for a quantitative assessment and for comparing similar technologies. In order to properly assess the origins of energy losses in the given system, an exergetic analysis has to be applied. The paper describes the rules of exergetic diagnostics, which greatly extends the potential of classic thermal diagnostics. A calculation example of a combined cycle power plant is included. The example demonstrates the potential of exergetic diagnostics for locating exergy losses and explains the reasons for increased consumption of fuels by comparing two working conditions of the system: reference and operational.
W praktyce do oceny efektywności termodynamicznej działania elektrowni lub elektrociepłowni stosuje się narzędzia tak zwanej diagnostyki cieplnej opartej na bilansowaniu energetycznym. Analiza energetyczna nadaje się jednak wyłącznie do oceny ilościowej oraz porównywania podobnych technologii energetycznych. Dla prawidłowej oceny miejsc i przyczyn powstawania strat w systemach energetycznych konieczne jest zastosowanie analizy egzergetycznej. W artykule zaprezentowano zasady diagnostyki egzergetycznej, znacznie poszerzającej potencjał klasycznej diagnostyki cieplnej wraz z przykładem obliczeniowym dotyczącym elektrowni gazowo-parowej. Diagnostyka egzergetyczna jest techniką z zakresu zaawansowanej analizy egzegetycznej, pozwalającą na szczegółową detekcję przyczyn generowania strat w komponentach z uwzględnieniem tak zwanych przyczyn wewnątrzpochodnych i zewnątrzpochodnych. Procedury diagnostyki egzergetycznej, w połączeniu z technikami modelowania matematycznego, pozwalają na poszerzoną kontrolę eksploatacji procesów i systemów produkcyjnych. Ponadto umożliwiają one dekompozycję kosztu egzergetycznego pomiędzy składowe wynikające z wzajemnych powiązań pomiędzy komponentami systemu. Zaprezentowany przykład obliczeniowy dotyczący elektrowni gazowo-parowej prezentuje potencjał diagnostyki egzergetycznej w zakresie lokalizacji strat egzergii i wyjaśnia przyczyny zwiększonego zużycia zasobów zasilających system poprzez porównanie dwóch stanów: referencyjnego oraz dowolnego stanu eksploatacyjnego systemu.
