In gas power plants, a lot of energy is lost in the form of heat more than the electricity produced. In the present research, techno-economic evaluation of combined power, desalination and cooling systems running by the exhaust flue gases of a gas turbine in Iran is performed. In addition to using power generated by the gas turbine, attempts were made to use Organic Rankine Cycle to recover the...

load management and cost optimization are among the important factors in trigenerationsystems and combined cooling, heating and power (cchp) systems. in this study, an innovative cchpsystem uses a gas turbine as the prime mover and has a heat recovery steam generator (hrsg) in addition toan auxiliary boiler, electric and absorption chillers. the system is tied with the bulk electric grid; to ex...

It is expected that residential units may replace   traditional heat and power production systems with cogeneration ones. Among the different cogeneration systems, fuel cell based systems are a suitable choice due to their high efficiency, high power density, low emission and low noise. In this paper, a cogeneration system based on solid oxide fuel cells is examined. The system, including the f...

Power system restructuring has increased the take part distribution side of power system in providing power. Extensive influence of distribution resources for generation power in distribution side of power system and transferring power electricity between retailer and household consumers are the reason of that.  Among  different types of distributed resources, micro combined heat and ...

Fuel flexibility is a significant advantage of solid oxide fuel cells (SOFCs) and can be attributed to their high operating temperature. The eligibility of a combined heat and power (CHP) system has been investigated as a new power generation methode, in this study. Natural gas fueled SOFC power systems via methane steam reforming (MSR) yield electrical conversion efficiencies exceeding 50% and...
