Exergy optimisation of a Brayton cycle-based cogeneration plant
An endoreversible Brayton cycle-based cogeneration plant has been optimised based on the dimensionless total exergy output rate criterion with a constraint on power-to-heat ratio. An optimal pressure ratio parameter and the maximum dimensionless total exergy output rate have been numerically determined. The optimisation results have been compared with those based on the total useful energy rate ...

Exergoeconomic optimisation of a Kalina cycle for power generation
It is shown that the use of an ammonia-water Kalina absorption power cycle as a bottoming cycle for a cogeneration plant may result in an economic advantage. This cycle was optimised using as a goal function the exergoeconomic unitary cost of the electricity produced by both the cogeneration plant and the absorption cycle. The Zoutendijk method of feasible directions was used for this ...

A real options–based approach in guaranteed energy savings contracting
The full development of the energy services company (ESCO) industry is still inhibited by the difficulties during the negotiation between customers and ESCOs. Contractual arrangements are traditionally based on energy performance contracting (EPC). Improvements on EPC schemes are required in order to achieve the success of the negotiation. This work focuses on a particular type of EPC, named ...

In view of sustainable future energetic–exergetic and economic analysis of a natural gas cogeneration plant
Thermodynamics plays an important role in performing energy and exergy analyses of industrial processes. The first law is widely used in engineering practice, and is the basis of the heat–balance method of analysis that is commonly used in energy systems performance analysis. However, the second law involves the reversibility or irreversibility of processes, and is a very important aspect ...

Thermal exergy optimisation for an irreversible cogeneration power plant
The optimal design model, based on exergy analysis, of an irreversible cogeneration cycle has been presented using finite-time thermodynamics. The external irreversibility is due to the thermal resistance between the system and the heat reservoirs while the internal irreversibility is due to the non-isentropic compression and expansion process within the system. The internal irreversibility of ...

Sustainable energy solution for cogeneration plant in a modern rice mill using paddy husk
As various technological and operational constraints exist in electricity distribution, many rural areas in India are deprived of power from the national electrical grid. In this situation sustainable energy solutions are the most viable and accessible sources for power production. Among the available sustainable resources, paddy husk is popular and has become a better and cheaper alternative for ...

Thermal design and emissions of duct-burners for combined-cycle and cogenerative plants
This paper mainly aims at demonstrating that an appropriate thermo-fluid-dynamic design optimisation of duct-burners for combined-cycle and cogenerative plants allows to satisfy restrictive emission limits, while significantly reducing the thermal stresses and the undesired pressure drops. In particular, a detailed discussion on the influence of the TEG composition and of the thermal load, ...

Thermodynamic evaluation of gas turbines for cogeneration applications
In this paper, the first and second laws of thermodynamics have been utilised to evaluate the performance of intercooled reheat regenerative gas turbine cogeneration plant. The effects of overall pressure ratio, cycle temperature ratio, pressure losses, and process steam pressure on energetic and exergetic efficiencies have been investigated. The results indicate that most of the exergy ...

Quantifying Combined Heat and Power (CHP) activity
In CHP plants without heat rejection facilities power, output is complementary to the recovery of heat, and all activity is cogeneration. CHP plants with heat rejection facilities can operate a mix of cogeneration and condensing activities. Quantifying the energy flows of both activities properly requires knowledge of the design power-to-heat ratios of the CHP processes (steam and gas turbines, ...

Energy conservation and electricity sector liberalisation in the Netherlands and the UK: case studies on the development of cogeneration of heat and power, wind energy and demand-side management as energy conservation options
In this article, the development of combined heat and power, wind energy and demand-side management in the UK and the Netherlands are compared. It is examined to what extent these developments are determined by liberalisation of the electricity sector in both countries. The analysis suggests that unbundling of generation and distribution, rather than privatisation or introduction of competition ...
