District Heating - Case Study
We want to offer a safe workplace! The network, which consists of a total of 105 miles, is from 1965 and thus one of the oldest in Sweden. Several studies have come to the conclusion that the best way to get away from problems such as corrosion would be to remove the chambers where the problems and risks are greatest, but because of the high maintenance costs, there is no economy for this. - It ...

Technical issues in low to medium-temperature district heating
Low-temperature district heating permits the use of energy resources formerly discarded or could not be claimed. However, its investment may be capital intensive because of equipment oversizing and temperature peaking required by conventional equipment. In classical design philosophy, flow is minimised in order to compensate some of the oversizing costs and to improve the utilisation rate of the ...

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 ...

Separation of CO2 during combustion of coal in a pressurised fluidised bed
The combustion of coal is accompanied by CO2 emissions. This carbon dioxide can be separated from the flue gases in the Combustion Chamber (CC) by means of adsorption on calcium oxide (carbonation) which in turn can be regenerated in a calcination process. A description of the processes and the integration in a whole power station that serves a district heating network and generates electricity ...

Thermodynamic analysis of a geothermal district heating system
Thermoeconomic analysis is considered a useful tool for investigators in engineering and other disciplines due to its methodology based on the quantities exergy, cost, energy and mass. This study deals with an investigation of capital costs and thermodynamic losses for devices in the Balcova Geothermal District Heating Systems (BGDHS). Thermodynamic loss rate-to-capital cost ratios are used for ...

Rational use and management of geothermal energy resources
This article identifies and explains several attributes of geothermal energy. High exergetic efficiency due to a close temperature tie between geothermal energy and district heating and cooling was noted. Parameters governing the rational use and management of geothermal energy systems with special emphasis on integrated-cascaded district energy systems were formulated and explained with two case ...

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. ...

Thermodynamic assessment of an integrated system for cogeneration and district heating and cooling
A thermodynamic assessment is reported of a proposed system, for which advanced engineering designs have been developed for integrating cogeneration with district heating and cooling. The system was developed by Edmonton Power for the city of Edmonton, Alberta, Canada. Energy and exergy analyses are used to attain a more complete thermodynamic understanding. The results provide a better ...

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 ...
