In the present study, a diesel engine based Combined Heat and Power (CHP) system is optimised using exergoeconomic concept and genetic algorithm. For this purpose, the CHP system is first thermodynamically analysed through energy and exergy. Then cost balances and auxiliary equations are applied to subsystems. Finally an objective function representing fuel cost, cost of exergy loss and ...

A detailed design optimisation study of an endo- and exoirreversible Stirling engine is carried out. After energetic, entropic and exergetic analyses of the hot-end and cold-end heat exchangers of the engine, an adapted model of the engine, including the heat exchangers and the regenerator, is proposed to optimise the distribution of the limited heat exchangers' total area. Power generation, ...

Operators of anaerobic digestion (AD) plants know how important it is to optimise energy use across all stages of the process. That is why many recapture as much heat as possible for reuse elsewhere, including from the hot exhaust gases generated by the combined heat and power (CHP) engines which turn the biogas from the AD plant into useful heat and electricity. Heat exchangers used for exhaust ...

This paper presents an investigation into the effect of biodiesel blending on emissions and efficiency in a stationary diesel engine. Rapeseed based biodiesel blended in increments of 25% with fossil diesel. The emissions of CO2 show a decrease in emission (g/kWh) with increased engine load. Within the range of tests carried out, the NOx emissions from biodiesel and its blends proved to be higher ...

Combined heat and power (CHP) systems which are able to produce heating and power simultaneously, are getting more attention since they have many economical and environmental benefits. CHP systems for buildings are an important application of CHP on various systems designs. In this study, we have investigated a CHP system applicable for the building of Azad University of Shahrood. The prime mover ...

District energy schemes seemed to be the right decision for the Aberdeen City Council (ACC). They had conducted a study of its housing stock and established that the multi-storey buildings (of which they have 59 in Aberdeen) were too expensive to heat. These buildings also had lower energy ratings, thus people living in them were subject to high energy bills. In 2002, as one of the results of the ...

An integral part of the majority of anaerobic digestion facilities across the world is the CHP combined heat and power (CHP) engine. For the first time builder of a biogas plant, it is often neglected as the focus is on reducing the capital costs of the installation. However, the engine is integral to the plant, and is the key component in the production of renewable electricity, hence the ...

Governments around the world are seeking to lower greenhouse gas (GHG) emissions in the fight against climate change, to reduce waste to landfill, and to increase their utilisation of renewable energy in compliance with international agreements. Consequently, in many countries, subsidies have been made available to encourage the growth of the biogas sector. According to the International ...
