Opis:: This paper presents a thermoeconomic analysis and assessment of a municipal solid waste power plant system in Gaziantep. The operation of an existing municipal solid waste power plant is described in detail and a thermoeconomical methodology based on exergoeconomic relations and specific exergy costing (SPECO) method is provided to allocate cost flows through subcomponents of the plant. SPECO method is based on a step by step procedure which begins from identification of energy and exergy values of all states defined in the present system through fuel (F) and product (P) approach and ends at the point of establishing related exergy based cost balance equations together with auxiliary equations. The actual exergy efficiency of the solid waste power plant is determined to be 47.84% which shows that 52.16% of the total exergy input to the plant is destroyed. The net electrical power output of the Gaziantep municipal solid waste power plant is 5.655 MW. The total cost rate of the power plant is evaluated as 18.44$/h as a result of thermoeconomic analyses.

Opis:: We developed a concept and calculated an efficiency of the electrochemical cycle of converting low-grade heat (temperature difference 10-80°C) into electricity. The cycle could be divided into two stages: creating a concentration difference by a solution distilled in a temperature gradient and electricity generation in concentration galvanic cell. The calculation shows that the efficiency of converting heat into electricity could reach 40-55% of Carnot efficiency in a temperature range of 0-100°C in the case of use of a multi-cascade distiller. The calculations show that ratio power/mass of the device is too low to be used in automobile or air transport, but it could be used in water transport.

Opis:: Dumping municipal waste is the least expensive and most commonly used method of disposing solid waste. However, there is an alternative, two-in-one, solution: conversion of waste to energy. Non-recyclable waste can be turned into heat, electric power or fuel using various processes, such as gasification, pyrolysis or anaerobic fermentation. This is how residual waste can serve as sustainable local source of energy, additionally, contributing to environmental protection and, to a significant extent, energy supply security.

Opis:: The purpose of this research was to process a mixture of paper waste and garden waste based on material flow analysis and to analyze its parameters based on water content, ash content, heating value, along with Thermogravimetry Analysis (TGA)/Derivative Thermogravimetry (DTG). The garden waste treatment process consists of shredding, drying with a rotary dryer, separator, and then shaving with a hammer mill. Paper waste only needs a shredder process. Then, the mixing process and pelletizing of paper waste as well as garden waste are carried out according to the variation (w/w) 100% paper (K100), 75% paper (K75), 50% paper (K50), 25% paper (K25), and 100% garden waste (K0). The water content ranged from 5.8 to 15.25%. From K0 to K100 samples, the ash content increased from 4.54 to 9.85%. A correlation of 0.9047 was found from samples K0 to K100. There was a correlation between increasing calorific value along with the mixture with paper waste. The caloric value in K0 to K100 increased from 13.11 to 19.03 MJ/kg. The TGA/DTG analysis reduced mass due to water evaporation, devolatilization, and carbonization processes.

Opis:: The Kingdom of Saudi Arabia (KSA) generates between 1.4–1.75 kg/person/day of Municipal Solid Waste (MSW) that accounts for over 16 million tons of MSW/year. The solid waste collected from different sources is dumped in landfills, thereby creating environmental concerns. In this paper, the potential of solid waste as an energy source (Waste to Energy (WTE)) for Reverse Osmosis (RO) water purification was evaluated. The KSA is known for its acute fresh water shortages and uses desalination technology in meeting its daily water requirements; a process that is energy intensive. The evaluation of the energy content of MSW shows a potential to produce about 927 MW in 2015, based on a total mass burn, and about 1,692 MW in 2032. The MSW-WTE plants can produce about 1.5% of the targeted 120 GW of energy for 2032. For the R.O system, it will give approximately 16.8% of the daily fresh water needed for total mass burn and 2.4% with the recycling option.

Opis:: Refuse Derived Fuels are used as energy carrier mainly in cement plants; however, more and more often they are applied in power plants as a substitute for fossil fuels. In order to prepare a proper waste-to-energy investment, the availability of the fuel, as well as fuel properties should be determined. The article presented the amounts of generated RDF in Poland, number installation which produced RDF in 2019 and 2020 and amounts of incinerated RDF in cement and incineration plants. The amount of generated RDF is rather constant – about 2.5 million Mg/year. RDF is mainly incinerated in cement plants – about 1.5 million Mg/year. The article also presented general physicochemical analysis of several RDF samples and coal. Some of the RDF samples reached high energy parameters – low heating value up to 25 MJ/kg; however, the properties vary a lot, due to their heterogeneous character, technological process of their production and other factors. In practice, the requested parameters and amount of RDF are established and the RDF producer prepares and delivers the fuel according to the concluded contract.

Opis:: Low-temperature heat sources have become increasingly popular in recent years, particularly for energy generation. The majority of thermal devices in the market (including devices using solar energy, geothermal energy, waste energy, and so on) transform heat into electricity indirectly, requiring mechanical work before producing power. Through the Seebeck effect, the technology that employs a thermoelectric generator (TEG) may directly transform heat energy into electricity. The TEG technology provides several advantages, including compactness, quietness, and the absence of moving components. TEGs have a low thermal and electrical efficiency, which is one of their main drawbacks. Therefore, the performance of a thermoelectric generator is improved by employing liquid evaporation heat transfer in this manuscript. The performance of the thermoelectric was examined experimentally and compared to the liquid evaporation mode under varied heat flux values and different modes of heat transfer in terms of free and forced convection with and without fins. The experimental results revealed that when compared to free convection without fins, adopting forced liquid evaporation convection would improve TEG voltage variation by 435.9%.

Opis:: Energy production from renewable sources is one of the main ways to fight against global warming. Anaerobic digestion process can be used to produce biogas containing methane. In the light of the growing demand for substrates, a variety of raw materials are required. These substrates should be suitable for anaerobic digestion, and processing them need to provide the desired amount of energy. This paper aims to discuss the agricultural biogas market in Poland, its current state, and the possibility of development during energy transformation, in particular in terms of using waste as a substrate for energy production. In February 2022, there were 130 agricultural biogas plants registered in Poland. On the other hand, in 2020, 4,409,054.898 Mg of raw materials were used to produce agricultural biogas in Poland. Among all the substrates used, waste played a special role. With the right amount of raw materials and proper management of a biogas plant, it is possible to produce electricity and provide stable and predictable heat supply. Bearing in mind the development of the Polish and European biogas markets, attention should be paid to ensure access to raw materials from which chemical energy in the form of biogas can be generated. Due to limited access to farmland and the increasing demand for food production, one should expect that waste will be increasingly often used for biogas production, especially that with high energy potential, such as waste related to animal production and the meat industry.

Opis:: This paper presents a concept for energy recovery in city buses, based on organic Rankine cycle (ORC) system modeling. ORC modeling provides preliminary parameters which enable estimation of transient state energy ﬂow, especially at those points in the system where it can mostly easily be recovered (exhaust, cooling and brakes). The paper describes an easy-to-use procedure for time-domain analysis of velocity waves in a real driving cycle. The results were combined with a dynamic system model of a city bus in block diagram environment, taking into account the inﬂuence of parameters assumed to have the greatest impact on the model’s accuracy. Average fuel consumption and producer speciﬁcations (maximum vehicle speed, rate of acceleration) were used as reference parameters. A procedure was developed for tuning the simulation model according to the reference parameters. The results of the simulation, based on real measurements of Lodz city traﬃc parameters, are discussed and an estimate is made of the potential for energy recovery in city buses.

Opis:: This paper presents the energy and exergy analyses of some different organic fluids which can be used in an organic Rankine cycle adapted to a municipal solid waste power plant in the frame of energy recovery. The novelty of the study is to adapt a well-known organic Rankine cycle system theoretically to the existing municipal solid waste power plant where the exhaust gas with a temperature of almost 560°C is sent to atmosphere causing both energy loss and air pollution, and also violating the related legislation. The efficient organic fluid that can be used in such a plant is estimated by means of the thermodynamic analyses. It is known that, in a typical municipal solid waste power plant, a considerable amount of energy is sent up from a plant chimney to the atmosphere. This waste energy can be utilized by using an adapted organic Rankine cycle system with a proper organic fluid. In this frame, some different organic fluids were examined and compared thermodynamically in this study. The optimal operation conditions of some organic fluids, R141b, isobutane, R245fa, n-pentane and n-hexane have been evaluated by means of ASPEN and EES software programs. The effects of the outlet temperature of heat source on the energetic and exergetic efficiencies and the net power output at a given pinch point temperature difference were investigated. It can be deduced from the analyses that n-hexane has the highest energetic and exergetic efficiencies at all outlet temperatures of the heat source such as 8.92% and 34.47% at 82.08°C, respectively. It can also be stated that the maximum net power output is obtained by using the organic fluid n-hexane.

Opis:: Thermoacoustics has become a promising technology to use heat from low temperature sources to drive engines. This study proposes a single-stage thermoacoustic travelling-wave engine for waste-heat recovery at 150°C. All the construction details of such a system are provided. A recently developed configuration of a looped tube with an impedance matching side-branch stub is proposed. A numerical model of the engine is built in DeltaEC software to conduct the simulations. Furthermore, a detailed thermodynamic analysis of the engine is presented, including an energy balance, a description of the basic acoustic parameters in a steady state, as well as a study of a variable load influence on the performance of the engine. The Authors pointed out the necessity of the engine optimization and a proper choice of load related acoustic impedance, which would consider a trade-off between high power and high efficiency. Eventually, a possibility of achieving 40% exergy efficiency of the proposed engine is confirmed.
