The paper describes two 3.9 MWth ammonia heat pumps of a District Heating plant which also includes two gas turbine cogeneration units. After nine years of reliable operation the heat pumps still show excellent coefficients of performance of above 4.1. Thi ...
Oxide dispersion strengthened (ODS) steels are candidate materials for advanced electric energy and heat generation plants (nuclear, fossil). Understanding the degradation of mechanical properties of these alloys as a result of service exposure is necessar ...
For the most part, district heating demands can be met by an appropriate integration of cogeneration and heat pumps units provided that advantage is taken of the fact that many urban regions are concentrated around surface waters. Such an integration resul ...
The optimisation of distributed and renewable energy systems in buildings has shown that zero energy systems, using existing technologies, is within reach in the household sector where the thermal and the systems can support each other to increase renewabl ...
A complex heating and cogeneration plant including two 3.9 MWth ammonia heat pumps and two 3 MWel gas turbines with heat recovery boilers and three storage tanks of 66 GJ has been in operation since 1986. The heating surface is actually about 280’000 m2 an ...
Valorisation of resources with the cogeneration of electricity and heat from the incineration of wastes is an important issue in modern societies. Present decision models aiming with minimizing the total costs associated with the optimum choice of configur ...
For the most part, district heating demands can be met by an appropriate intergration of cogeneration and heat pumps units provided that advantages is taken of the fact that many urban regions are concentrated around surface waters. Despite the fact that t ...
