Modeling and thermo-economic optimization of heat recovery heat exchangers using a multimodal genetic algorithm. A cost sensitivity analysis including the effect of coal price and average xngrisani capacity factor is performed. Detailed mass, energy, exergy and money balances for a reference steam power plant Harry Allen Station are shown.
The results allow quantifying as thermo-economic design optimization based on short term criteria as the payback time leads to smaller plants with higher solar field efficiencies and smaller solar fractions, while the consideration of optimization criteria based on long term performance of the plants, as life cycle savings based optimization, leads to the reverse conclusion.
Energy is not only a measure of the true thermodynamic value of an energy carrier but is also closely related to the economic value of the carrier since users pay only for the useful part of energy. I agree to the discuto. To accommodate the analysis, a numerical model of a transcritical booster refrigeration plant is considered in this paper. The complexity of these systems creates the necessity for tools that permit to evaluate their performance. Amazon Drive Cloud storage from Amazon.
The formulation is based on extending the thermoeconomic process of the cost formation of wastes in order to consider their use as input for other processes. Login to submit comment. The above procedure is performed for various mass flow rates in each side.
A conclusion from the previous project was that ANN modelling of thermal power plants and its components can be done with high accuracy. It is shown that under ecological conditions the plant dramatically reduces the amount of heat rejected to the environment, and a loss of profits is translated in an usage of fuels that dramatically reduces the heat rejected towards the environment in comparison to that obtained by means of maximum power regime.
This information is essential for the proper design of the ventilation system needed to disseminate the heat generated inside the container-housed unit. The derivatives of five system parameters on system performance are used to evaluate the parametric sensitiveness. Secondly, the model is applied to predict the feasibility of producing and implementing different biofuels i. Based on a synthesis plant of the hydrogen production unit, the exergy efficiency of each component and of the overall plant are calculated.
Using thermoeconomics as a tool to identify the location and magnitude of the real thermodynamic losses energy waste, or exergy destruction and exergy losses it is possible to assess the production costs of each product electric power and heat and the exergetic and exergoeconomic cost of each flow in a cogeneration plant to assist in decision-marketing procedures concerning to plant design, investment, operation and allocations of research funds.
Finally, thermoeconomics was applied to calculate the costs of the electricity and useful heat energy produced by the engine. This paper introduces a new concept that exergy input into the system can be substituted for the sum of exergy destruction and exergy output from the system according to conservation of exergy.
A further analysis of the ORC system using isobutane shows high sensitivity of the costs per unit exergy for the selected cost estimation methods and for the isentropic efficiency of the turbine.
Both the transcritical ORC and subcritical ORC are investigated and compared using the suggested optimization strategy. El metodo de cortes minimos consta de dos grandes pasos: The influences of evaporating pressure, engine type and load on the system performances are analyzed with multi-objectives, including the thermal efficiency improvement, the reduced CO 2 emission, the total heat transfer area per net power output APPthe electricity production cost EPC and the payback period PBP.
Part I – Methodology. In this work, we study the thermoeconomics of a non-endoreversible simplified thermal power plant model, the so-called Novikov engine. The models representing the components, the thermo-economic objective function and the buildings have been implemented in a widely used commercial software for building simulations.
The effects of mass fraction of Rfa and four key parameters on the exergy efficiency and LEC are examined. This study focuses on the evaluation and optimization of the thermodynamic and economic performance of methanol production from biomass by applying process integration and optimization techniques.
Thermo-economic analysis of recuperated Maisotsenko bottoming cycle using triplex air saturator: Results indicate that modifications in certain process parameters can lead to a decrease in the cost of electricity produced by the reference plant.
The focus is on dual fuel gas turbine cycle, where compressed air is heated in a high temperature heat exchanger HTHE using the hot gases produced in a biomass furnace, before entering the gas combustion chamber. The paper is Part 2 of the study on the thermodynamic and thermoeconomic analyses of trigeneration system with a gas-diesel engine. A furnace for heating air is evaluated using the methodology. Life cycle cost at thermoeconomic optimization is lower than that at thermodynamic optimization.
An extensive set of optimization cases are performed to estimate the influence of fuel price trend, plant location, demand profile, operation conditions, solar field orientation, and radiation uncertainty on contabilkdad design. In this paper, thermo-economic comparisons of organic Rankine and steam Rankine cycles powered by line-focusing concentrating solar collectors are reported.
The first mode assumes no storage, while the angrisanj and the third assume a storage system with a storage period of 7.

The system current status and its evolution according to the planning of short and medium period are analysed. A detailed sensitivity analysis was performed to examine the impact of the variation of contabikidad cost, load and availability factors in addition to capital recovery factor on electricity and water production costs.
The engine efficiency rates were evaluated on both an energy qngrisani exergy basis, taking into account that heat from the cooling circuit and exhaust fumes are used for CHP. As such, a novel framework for designing optimized ORC systems is proposed based on a multi-objective optimization scheme in combination with financial appraisal in a post-processing step.
This is completed with a thermoeconomic analysis of the kW cogeneration fuel cell power plant which was subsequently built. Confirm your account info: Thermo-economic optimization of a parabolic trough solar plant design for the reference industrial.
The Scope Oriented Thermoeconomic optimization allows us to disassemble the optimization process, thus recognizing the Formation Structure of Optimality, i. Registraciones en el Libro Diario General. This paper represents the Part II of a paper in two parts.
