A thermodynamic model of a thermoelectric generator-driven thermoelectric heat pump (TEG-TEH) combined device is established considering the Thomson effect and the temperature dependence of the thermoelectric properties based on non-equilibrium thermodynamics. Energy analysis and exergy analysis are performed. New expressions for heating load, maximum working temperature difference, coefficient...

exergy analysis of an integrated molten carbonate fuel cell-turbo expander-steam turbine hybrid cycle has been presented in this study. the proposed cycle has been used as a sustainable energy approach to provide a micro hybrid power plant with high exergy efficiency. to generate electricity by the mentioned system, an externally reformed molten carbonate fuel cell located upstream of the combi...

the exergy analysis is a proper method for performance evaluation of industrial systems. a generic and detailed analysis of the gpcss on the second gas pipeline of iran  is made by the means of exergy. the two main improvement measures of fuel pre-heating and steam injection technologies are presented for the current conventional stations. steady state equations regarding the second law of ther...

Abstract Energy cost and consumption are increasing, so that efficiency becomes more important, from the production to end users. reserves limited; increasing demand environmental concerns make important. To provide cost-effective clean power generation, gas turbines cogeneration becoming key technology must be researched developed. Three different cycles analyzed by using first second laws of ...

The escalating freshwater demand is stimulating the researchers to optimize performance of desalination technologies. current study presents exergoeconomic optimization a forward feed multi-effect (FF-MED) system under two configurations i.e., conventional MED and with energy recovery (MED-ER). A detailed numerical model concerning energy, exergy, component-based analysis employed estimate cons...

This research presents the energy, exergy, economic, and environmental assessment, multi-objective optimization of a flash-binary geothermal CCHP cycle. A sensitivity analysis production well inlet temperature cooling to power flow ratio on exergetic, parameters was conducted. Furthermore, effects inflation rate plant working hours economic were investigated. Results showed that increasing harm...

This paper uses the energy hub concept to meet the water, heat and electricity demand of a power plant in the Qeshm island in south of Iran. Given the power plant’s high potential for waste heat recovery and some scenarios were considered using the hub energy concept based on energy, exergy, environmental and economic analyzes in terms of meeting the demands of the hub and purchasing/selling en...

nowadays, energy plays an important role in the economic and community development of country. consequently, performance analysis of energy systems is one of the effective methods being used to prevent waste of energy resources. among the different power generation technologies, steam power plants make a significant contribution to power generation in iran, with a share of 47 % of electricity g...

A huge amount of energy is consumed during sugar production in the food industry. The large amount of steam used and the power of the turbine power plant are key factors. This makes energy and exergy analysis important in sugar factories. The data given in the following paper are related to input and output information of the paper entitled Energy - exergy analysis and optimisation of a model s...
