Opis:
Humankind faces the most serious challenge ever – sustainable development. A new paradigm based on respect of nature and awareness of natural mechanisms is needed. The concept of exergy and exergy based methods offers a unique potential to support this. Applications to real problems and possible solutions are presented and applied to living systems and the process of sustainable development. In particular, implications on the educational systems are addressed.
Ludzkość staje przed największym jak dotąd wzywaniem, którym jest konieczność wprowadzenia rozwoju zrównoważonego. Potrzebny jest tu nowy paradygmat oparty na szacunku wobec przyrody i znajomości mechanizmów rządzących naturą. Koncepcja egzergii i jej metody stanowią ogromny potencjał, który należy tu wykorzystać. W pracy powiązano teorię egzergii z problemami występującymi w realnym świecie, dyskutując możliwe rozwiązania, odnosząc je zarazem do żywych systemów i procesów związanych ze zrównoważonym rozwojem. W szczególności, podkreślono implikacje odnoszące się do systemów edukacyjnych.

Opis:
The paper is devoted to the problems of exergetic cost determination. A brief description of theoretical fundamentals of exergetic cost determination and its application are presented. The applied method of calculations is based on the rules of determination of cumulative exergy consumption. The additional possibilities ensured by the exergetic cost analysis in comparison to the direct exergy consumption analysis are discussed. The presented methodology was applied for the analysis of in.uence of operational parameters on exergetic cost indices of steam power plant. Results of calculations concern one of the modern Polish power plant unit. Basing on the obtained results several conclusions have been formulated that show advantages of application of exergetic cost analyses.

Opis:
The article presents an experimental-theoretical analysis of fluidised-bed drying of poppy seeds directed on minimisation of energy. The analysis was performed for a complete drying node incorporating a heat exchanger and a fan. Two complementary factors were used in the exergetic evaluation: exergy efficiency and unit consumption of exergy. An analysis of drying in stationary bed was carried out for comparison purposes. Results of the exergetic analysis can become a basis for innovative works focused on decreasing energy consumption of a technological node being analysed, e.g. by the use of recirculation of fluidising-drying medium.

Opis:
In this work, a new dual-evaporator CO2 transcritical refrigeration cycle with two ejectors is proposed. In this new system, we proposed to recover the lost energy of condensation coming off the gas cooler and operate the refrigeration cycle ejector free and enhance the system performance and obtain dual-temperature refrigeration simultaneously. The effects of some key parameters on the thermodynamic performance of the modified cycle are theoretically investigated based on energetic and exergetic analysis. The simulation results for the modified cycle indicate more effective system performance improvement than the single ejector in the CO2 vapor compression cycle using ejector as an expander ranging up to 46%. The exergetic analysis for this system is made. The performance characteristics of the proposed cycle show its promise in dual-evaporator refrigeration system.

Opis:
In this work, actual operating data for Sabiya combined cycle power plant located in Kuwait were used to conduct the performance evaluation based on the energetic and exergetic analysis. The proposed system consist of an advanced gas turbine engines, with two triple pressure reheat heat recovery steam generator, and one steam turbine. Three types of primary movers were selected carefully, in order to cover different types, sizes and technologies. The movers are gas turbine engine frame 9FA, LM6000 and GT26. The proposed models have been developed using specialised software and validated with the manufacturer’s data featuring a high level of compatibility. The performance of a combined cycle power plant was investigated for different operating conditions. The result shows that the highest exergy destruction takes place in 9FA engine due to high irreversibility in combustion chamber because of low-pressure ratio, which causes low inlet temperature of compressed air to the combustion chamber. The 9FA engine also has the highest exergy loss due to high exhaust gases temperature, which is caused high useful work from a steam turbine. The GT26-reheat gas turbine engine constitute the best choose as primary mover due to low waste exergy, which is equal to 43.93% whereas 9FA and LM6000 equal to 47.27% and 45.17%, respectively. LM6000 aeroderivative gas turbine is considered the second best choice but the combined cycle power plant will consist of a large number of engines compared to other industrial gas turbine engine, and that may increase the number of auxiliary equipment, capital and maintenance cost.

Opis:
In order to analyze the cumulative exergy consumption of an integrated oxy-fuel combustion power plant the method of balance equations was applied based on the principle that the cumulative exergy consumption charging the products of this process equals the sum of cumulative exergy consumption charging the substrates. The set of balance equations of the cumulative exergy consumption bases on the ‘input-output method’ of the direct energy consumption. In the structure of the balance we distinguished main products (e.g. electricity), by-products (e.g. nitrogen) and external supplies (fuels). In the balance model of cumulative exergy consumption it has been assumed that the cumulative exergy consumption charging the supplies from outside is a quantity known a priori resulting from the analysis of cumulative exergy consumption concerning the economy of the whole country. The byproducts are charged by the cumulative exergy consumption resulting from the principle of a replaced process. The cumulative exergy consumption of the main products is the final quantity.

Opis:
This study investigates the recovery of wasted heat in the cement plant industries (Neka Cement Factory) in order to reduce the use of fossil fuels and greenhouse gas emissions. Cement is the most widely used man-made material. The global cement industry produces about 3.3 billion tons of cement annually. A lot of energy is needed to produce cement. About 200 kg of coal is used to produce each ton of cement. The cement industry also produces about five percent of the world's greenhouse gases. The method studied in this research is based on heat recovery from boilers installed at the outlet of a clinker cooler and a preheater in a cement factory. Due to the low temperature of the gases available, three different fluids, i.e. water, R134a and R245fa were considered as the operating fluids. Also, energy and exergy analyses are performed in a Rankin cycle and the selection of optimal parameters is considered by using genetic algorithm. The results of this study showed that water with optimized parameters leads to an increase in the production capacity from 5 to 9 MW. However, fluid R134a with optimized parameters leads to a 4% increase in exergy losses and it also increases the production capacity from 5 to 9 MW.

Opis:
The selection of suitable working fluid for simple and recuperative organic Rankine cycle (ORC) operating under subcritical, superheated and supercritical conditions are investigated. 11 fluids with critical temperature above 1500C are considered as potential candidates. Performance screening parameters such as net power output, thermal efficiency, turbine sizing parameter (SP) and volumetric flow ratio (VFR), exegetic parameters like irreversibility rate, fuel depletion ratio, and improvement potential rate of exergy destruction were also evaluated. Results indicate that R600a, R236fa and R1233dz(E) demonstrated the best performance for subcritical, superheated and supercritical simple ORC, respectively. R236fa and R1233dz(E) proved more suitable for subcritical/superheated and supercritical recuperative cycles, respectively. The system exegetic efficiency is reveal to be significantly higher in subcritical/superheated (61-65%) cycles compared to the supercritical (35-45%) cycle, the evaporator seen as the main source of exergy destruction, accounting for 17-37% of inlet exergy destroyed and about 8-24% in the turbine.

Opis:
Sustainability has become of paramount importance in the biofuel industry. Accordingly, various sustainability assessment schemes such as emergy analysis, techno-economic analysis, life cycle assessment, energy accounting, and exergy analysis and its extensions (exergoeconomic, exergoenvironmental, and exergoeconoenvironmental analyses) are being employed increasingly for decision-making on biofuel production and consumption systems. In this opinion paper, after classifying and describing biofuel generations, the developed sustainability assessment tools are critically explained, and their pros and cons are discussed. Overall, among the various sustainability assessment approaches introduced so far, exergy-based methods appear to be the most promising tools for developing sustainable biofuel systems. This can be attributed to the fact that the exergy concept is deeply rooted in the well-defined principles of thermodynamics.

Opis:
The increase in demand for natural gas in the world, cause that the production of liquefied natural gas (LNG) and in consequences its regasification becoming more common process related to its transportation. Liquefied gas is transported in the tanks at a temperature of about 111K at atmospheric pressure. The process required to convert LNG from a liquid to a gas phase for further pipeline transport, allows the use of exergy of LNG to various applications, including for electricity generation. Exergy analysis is a well known technique for analyzing irreversible losses in a separate process. It allows to specify the distribution, the source and size of the irreversible losses in energy systems, and thus provide guidelines for energy efficiency. Because both the LNG regasification and liquefaction of natural gas are energy intensive, exergy analysis process is essential for designing highly efficient cryogenic installations.
Wzrost zapotrzebowania na gaz ziemny na świecie powoduje, że produkcja skroplonego gazu ziemnego (LNG), a w konsekwencji jego regazyfikacja, staje się coraz bardziej powszechnym procesem związanym z jego transportem. Skroplony gaz transportowany jest w zbiornikach w temperaturze około 111K pod ciśnieniem atmosferycznym. Przebieg procesu regazyfikacji niezbędny do zamiany LNG z fazy ciekłej w gazową dla dalszego transportu w sieci, umożliwia wykorzystanie egzergii LNG do różnych zastosowań, między innymi do produkcji energii elektrycznej. Analiza egzergii jest znaną techniką analizowania nieodwracalnych strat w wydzielonym procesie. Pozwala na określenie dystrybucji, źródła i wielkości nieodwracalnych strat w systemach energetycznych, a więc ustalić wytyczne dotyczące efektywnego zużycia energii. Ponieważ zarówno regazyfikacja LNG jak i skraplanie gazu ziemnego są energochłonne, proces analizy egzergii jest niezbędny do projektowania wysoce wydajnych instalacji kriogenicznych.

Exergy analysis of a bakery stove, carried out with the use of exergy balance of this object was presented in the paper. With the use of balance data, assessment of internal and external exergy losses during baking process in the four-chamber cyclometric stove, used for baking a wide assortment of bakery products, was carried out. The obtained calculation results showed that the internal exergy loss constitutes 41.04% of exergy supplied to the system and the external – 58.89%. Those values are the measure of the quality of energy, which may be recovered and used for heating purposes or may be subjected to conversion into other forms of energy. It concerns, as a rule, the loss of external exergy because the internal one was dispersed.
W pracy przedstawiono analizę egzergetyczną pieca piekarniczego, przeprowadzoną za pomocą bilansu egzergetycznego tego obiektu. Wykorzystując dane bilansowe przeprowadzono ocenę strat egzergii wewnętrznej i zewnętrznej podczas procesu wypieku w piecu cyklometrycznym, czterokomorowym, stosowanym do wypieku szerokiego asortymentu produktów piekarniczych. Otrzymane wyniki obliczeń pokazały, że wewnętrzna strata egzergii stanowi 41,04% egzergii doprowadzonej do układu, a zewnętrzna – 58,89%. Wartości te są miarą jakości energii, którą można odzyskać i wykorzystać do celów grzewczych lub poddać konwersji na inne postacie energii. Dotyczy to w zasadzie straty zewnętrznej egzergii, ponieważ wewnętrzna ulega rozproszeniu.

Opis:
The Colombian mining sector is characterized by the production of coal, nickel, emeralds, gold, and construction materials. It is considered by the National Development Plan of Colombia 2018-2022 as an economic agent that boosts development in the region and one that requires the strengthening of its policies and environmental liability. Therefore, this paper aims to show the importance of implementing methodologies based on the logic of nature (exergy) that objectively indicate the environmental impact of an extractive gold activity, such as open-pit gold mining. The extractive activity or process to be studied consists of the following stages: topsoil removal by using machinery and explosives to create craters and to access the mineral present in the subsoil; the physical transformation of the extracted material through crushing, grinding, gravimetric separation, flotation, leaching, adsorption, elution, and electrodeposition, along with smelting and casting to obtain gold and silver ingots. Thus, this paper analyzes the exergy performance of each unit process of the open-pit extractive process. The obtained results are used in a sensitivity analysis, which determines the system efficiency, by assuming the increase of gold in the extracted material in the exploitation stage, by using the same supplies and input of the current process. In other cases, the open-pit mining process is analyzed by changing its technologies in the mining process and assuming that this change reduces the inlet ore to 60%, by discarding 40% of material without gold and by reducing supply consumption by 25%. By improving the system efficiency, the exergy destroyed is reduced and the emissions to the environment diminish. Therefore, this method may be implemented as a basic guideline when it comes to decision-making processes in the planning of the extractive processes by integrating the environmental component with gold production.

Opis:
The paper presents pursuits of the truth in building materials engineering. Some definitions of “what truth is” were presented. Partial truths were specified: the truth of scientific reasoning, the truth of scientific assessment, the truth of development directions and the splendour of scientific truth. All categories are addressed to the building materials engineering. In the chapter “Load capacity and stability vs entropy” definitions of entropy and exergy were presented followed by their influence on building construction, illustrated by the “Seneca cliff” and “Energy pyramid”. Chapter 3 presents the truth of scientific reasoning was presented. Three partial truths were indicated: the truth of experimental fact, the truth of scientific reasoning and the truth of scientific presentation. In the chapter “Truth of scientific assessment” two main assessment methods were presented: peer review and a bibliometric parametric assessment as well as their impact on the results and authors. The risks associated with the sole parametric assessment were shown as the two basic factors of a parametric assessment – citation number and Hirsch index – need time to "mature". Additionally, the influence of digitalisation of the assessment of a scientist and a scientific unit on the commoditisation and dehumanisation of science was outlined. In the chapter “Truth of development directions: defined past – fuzzy future” the megatrends observed in technology in the last few decades years were indicated along with new possible trends. Milestones in the development of C-PCs (Concrete-Polymer Composites) were presented. The new paradigm for the new development cycle was proposed.
Artykuł jest osobistą refleksją autora nad wywiązaniem się ze ślubowań akademickich dociekać prawdy, głosić ją oraz dawać świadectwo, a także doktorskich - aby szerzyła się coraz bardziej prawda, od której zawisła przyszłość i szczęście rodzaju ludzkiego. Rozważania te są zaadresowane do Inżynierii Materiałów Budowlanych – obszaru nauki, który formalnie nie był zdefiniowany ani wyodrębniony w momencie składania ślubowań. Nauka może być zdefiniowana jako dążenie do prawdy; w prawdzie zaklęty jest cel, ale i etos nauki. Postęp nauki nie zawsze prowadzi prostą drogą do prawdy. Często odpowiadamy tylko na pytanie czy model opisujący dane zjawisko jest wystarczająco prawdziwy. Prawda inżynierii materiałów budowlanych ma nie tylko wymiar wartości, ale również waży materialnie. „Prawdziwość” metody pomiaru może decydować o bezpieczeństwie konstrukcji, ale również istotnie znaczy w jej koszcie. Obszar rozważań został określony jako relacja „materiał – konstrukcja” i przypisano tu myśl przewodnią „nośność i stateczność a entropia”.
