“…There are a limited number of studies concerning the CHP plants because of the relatively small amount of coal consumed. However, most coal-fired CHP plants are located in the center of cities and may cause higher health risks (Peng et al, 2008). In order to minimise the potential environmental risk of CHP plant, it is essential to understand the behaviour of trace elements in fly ash during the combustion process.…”

The levels of trace elements and polycyclic aromatic hydrocarbons (PAHs) in fly ash generated by coal combustion have received considerable attention in recent years, due to their potential environmental impact. Sixteen high priority PAHs and 14 trace elements in coal fly ash were measured. The particle sizes of fly ash showed a bimodal distribution, and most ash particles were within a range of 20-25 µm in diameter. The fly ash exhibited high contents of CaO and SO 3 , which was influenced by the desulfidation treatment of limestone. The Be, Cu, Ni, V, Se, Mo and Cd contents increased significantly with decreasing particle sizes of fly ash, while those of Zn and Pb showed no obvious trends. PAHs with three-and four-rings were the dominate species in all the fly ash. The amount low molecular weight PAHs with two-, three-and four-rings was inversely correlated with the particle sizes of the fly ash.

“…• Comprehensive quantification methodology, such as an energy analysis that allows direct comparison of the impacts of many small-scale bioenergy systems (a "virtual power plant") versus a few large-scale ones, needs to be developed and deployed (Peng et al, 2008). • Criteria and indicator frameworks to assess sustainability need to be developed for bioenergy systems to allow quick assessments.…”

The role of power and thermal energy is impossible to overestimate in development of both state economy sector and everyday life of households. Importance is connected with use of resources, economical feasibility and effect to climate changes. The optimization of energy production allows to promote development of sustainable society. The most popular and efficient technologies for generation of power and thermal energy are cogeneration plants (CHP). Traditional evaluation methodologies of energy production systems are based on analysis of energy and mass balances as well as on cost analysis. It is not enough for assessment of complete sustainability of system. Necessary environmental impact assessment of energy production is possible to implement by use of emergy analysis. Definition of emergy includes one type of energy, which is used directly or indirectly to produce materials, provide services and finances. Emergy dimension is emjoules (seJ.). Paper presents case study of emergy analysis of different operation modes of one cogeneration plant.
