Energy and exergy analysis of a 16–MW combined cycle district heating system with performance improvements
Results of an energy and exergy analyses performed on a 16–MW University district heating plant located in the Northeast USA are presented in this paper. Unlike past studies, this paper uses actual data to assess CHP plant performance for all the 8760 h in a year (2011). A system of such complexity, considering the large volume of data available and large variations in system load, has not been ...

Technical note: An approximate examination of the effects of esterification on the EROEI of biodiesel fuels
Heat balance calculations on esterification of plant oil to make biodiesel are performed using recently published information from a laboratory reactor. It is concluded that such energy is relatively small and that attempts to improve the EROEI of biodiesels should not focus on the esterification process. [Received: January 8, 2009; Accepted: September 25, 2009]Keywords: biodiesel, ...

Focus Bioenergy No 3 2004: Forest industry - a major user and supplier of biofuels
Forest industry is a major user and supplier of biofuels. Sawmills use bark and shavings internally as fuel. The surplus goes to district heating plants, production of refined biofuels and the board industry. Other residual products from the sawmills are chipped. The bulk, the damp chips, is used for paper pulp in the pulp industry, whereas dry chips go to the fuel sector. The pulp industry uses ...

Evaluating the concentrations of partitioned heavy metals in fly ash from a medium-sized (32 MW) municipal district heating plant with respect to the new Finnish limit values
The total heavy metal concentrations in the fly ash were clearly lower than the Finnish limit values for forestry fertilisers, and for material used as an earth construction agent, which came into force in March 2007 and in June 2006, respectively. The relatively low heavy metal concentrations, the alkaline pH (12.5) and the elevated Ca concentration (139.5 g kg−1; d.w.) indicate that the fly ash ...

Exergy analysis of a steam power plant: a case study in Iran
In the last decades, exergy analysis, based on the second law of thermodynamics was a method that substituted the energy analysis in studying thermodynamic systems. In this paper, the cycle of a power plant and its details, with two kinds of fuels, natural gas and diesel, have been analysed at its maximum load and the two factors, losses and exergy efficiency, which are the basic factors used to ...

Solutions for the exploitation of biomass energy in mountain regions
Using tow-cables to extract and transport biomass to forest paths Many forests are located on mountainous terrain with steep slopes, making their exploitation not economically viable, at least with traditional methods. This can lead to the abandonment of such hilly woodlands, giving rise to rodent infestation or forest fires, with resulting damage to the woods themselves and to surrounding ...
