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 ...

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 ...

Design of optimal power cogeneration for North-east Sri Lanka based on stand-alone renewable energy systems
This article presents an optimal model to satisfy electricity needs of North-east Sri Lanka (NE-SL). With the absence of indigenous fossil fuel and large-scale hydrologic resources, NE-SL depends on the import of fossil fuel for electricity generation, causing economic and environmental hardships. This article explores a sustainable power generation using a mix of renewable energy ...

Novel cogeneration cost-sharing mechanism for energy savings and emission reduction in China
Cogeneration can improve the efficiency of energy utilisation, improve energy savings and reduce carbon emission. However, China currently suffers unreasonable cogeneration pricing and cost sharing, which has seriously hampered the development of cogeneration power plants. Based on the production process of cogeneration, this paper analyses the principles of thermoelectric cogeneration and energy ...

The recent development of biomass energy in India: an overview
This paper presents the current status and use of Biomass Technologies (BTs) in India. Different technology routes such as gasification, combustion and cogeneration are being actively developed to promote conversion of biomass materials such as agricultural, forestry and agro-industrial residues into electric power. The promotion of scientifically designed models of wood/biomass fired efficient ...

Biogas purification in EDAR Mapocho - Case Study
BIOCONSERVACION: Integral solution for biogas purification in WWTPs Biogas is mainly composed by methane and carbon dioxide as a result of organic matter fermentation in the absence of air by the action of a microbial consortium (anaerobic digestion). The composition of biogas depends entirely on the nature of the waste processed and the conditions under which takes place the anaerobic ...
