Enhancing the sustainability and diversification of Iraq’s electricity system is a strategic objective. Achieving this goal depends critically on increasing use renewable energy sources (RESs). The significance developing solar-powered technologies becomes essential at point. Iraq, similar to other places with high average direct normal irradiation, good location for concentrated solar thermal ...

Finite time exergoeconomic performance of a combined cooling, heating and power generation (CCHP) plant composed of one endoreversible closed Brayton cycle and one endoreversible four-heat-reservoir absorption refrigeration cycle is investigated by using finite time thermodynamics. Heat conductance distribution among hot-, cold-, thermal consumer-, generator-, absorber-, condenserand evaporator...

This study is part 2 of the investigation on exergetic and exergoeconomic parameters an existing system with air-to-water heat pump unit as a source. Part 1 presents used experimental setup. The main aim conducted tests to develop models produced rate energetic COP at different ambient conditions. obtained data in where exergetinc assessment carried out. analysis was performed dynamically chang...

In the present research, energy in geothermal fluid is utilized to generate power. first case of power generation, model double-effect instantaneous evaporation cycle employed, and second one, single-effect combined Rankine with different organic fluids are utilized. The effect several examined. SPECO method has also been applied economic analysis. Given analysis, net generation highest for wat...

In this paper, a small scale biomass gasification based solid oxide fuel cell/gas turbine (SOFC/GT) combined heat and power (CHP) plant is investigated by means of both conventional advanced exergy exergoeconomic analysis. A one-dimensional model an internal reforming planner SOFC employed to account for the temperature gradient within cell structure, which maintained at maximum allowable (150 ...

Combined cycle systems have an important role in power generation. In the present study, three different configurations of combined Brayton and Rankine system are studied from perspective energy, exergy, exergoeconomic environmental perspectives. Results indicate that it depends on preferences criteria each decision maker to select best configuration among proposed as final configuration. For p...
