Cogeneration Plant Articles & Analysis

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 ...

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 ...

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 ...

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 ...

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 ...

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, ...

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 ...

When Siouxland Ethanol, located in Jackson, Nebraska, USA decided to invest in a combined heat and power system (CHP), or cogeneration, it needed to make decisions regarding the plan's air abatement and compliance. The company wanted to take its current system, a heat recovery steam generator (HRSG) offline and replace it with a boiler to form a cogeneration plant. With this approach, the steam ...

Cogeneration is the process of generating both electrical and heat energy from a single fuel source. Also known as Combined Heat & Power (CHP), cogeneration makes use of the commonly discarded thermal energy which is generated from the combustion of fuels such as diesel, natural gas, bi-fuel, and even heavy fuel oil (HFO). The entire CHP process revolves around fuel-driven electric ...
