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 ...

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 ...

Practical application of the RUTA safe pool-type nuclear reactor to demonstrate the advantages of atomic energy use
The concept of the RUTA water-cooled, water-moderated pool-type nuclear reactor is presented. The basic findings of the RUTA-70 pilot district-heating plant in the science town of Obninsk, Kaluga Region, Russia, and its capabilities for nuclear technology research purposes, are shown. The basic technical data of the reactor facility are presented and its design is described in brief. The ...

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 ...

District Heat Network/Power Plant - Case Study
In CHP plant, even a small amount of very fine particle contamination, e.g. magnetite below 1 μm, lowers the efficiency of the heat distribution system and may result to uncertainty in measurement equipment. The solids are removed from sidestream by automatic Sofi Filter unit.The applicability of Sofi Filter is wide. Please visit our website www.sofifiltration.com for more information. ...

Heavy metals in wet scrubber residue from a medium–sized (32 MW) municipal district heating plant incinerating wood and peat in a fluidised bed boiler
Due to the low total concentrations of heavy metals and extractable compounds, it is recommended that the wet scrubber residue be used as a construction agent instead of being disposed of in landfills. According to five–stage sequential extraction, the highest concentrations of most of the heavy metals occurred in the residual fraction (i.e., HF + HNO3 + HCl), which means that the heavy metals in ...

Heat recovery and energy efficiency, improves profitability and reduces CO footprint
Using latest technology in combustion of oil and gas can provide significant savings in overall energy consumption. Modern oxygen control that compensates changes in ambient temperature and fuel qualities can increase energy efficiency up to 3%. By adding the usage of hot combustion air another 2-3% can be saved. Modern burner technology without mechanical linkage, operating with accurate ...
