Through the approval of the Kyoto Protocol, the ONU Convention held in Europe and has taken to reduce the emissions of sulfur in large combustion installations through the development of projects for desulphurization flue gas in coal burning power plants to improve the reports relating to the...

The main objective of the paper is to highlight the evolution of the energetic and environmental performances of a condensing and cogeneration 150 MW power plant which for different loading levels. The values obtained from the creation of the real hourly thermalenergetic balance were graphically...

We popose a calculation method by which we can estimate the value of the loss of pressure along the pipeline, the loss of pressure per length meter of network and the cost of the pneumatic energy loss in the case of the horizontal and vertical pneumatic network. The proposed method is validated...

It was determined, interpreted and compared continuous emissions from energy units from CET Mintia. The values obtained are included in the amount specified under the rules of Romania.

The exergetic model is superior to other methods of study of mining pneumatic networks thermal processes. It allows us to find out the energy losses and exergetic efficiency. Thus, we have more opportunities for increasing these installation performances

The compressed air flow in the pneumatic networks is studied from thermodynamic point of view. Generally speaking, the flow issue is presented as next: knowing the characteristics p1 (pressure), v1 (specific volume), T1 (temperature) and the fluid speed w1, in the initial section (point 1), of a...

Most interesting appearance in under consideration exergetic concerning the helical screw compressor represents it the possibility identified the weakly point from the cycle of operation. The identification and then improvement weakly points will permit the utilization energies in superior...

The fresh calculation of the centrifugal-type compressor characteristics at the aspirations parameters and rotations modification has a significant importance in practice, because the tests of compressors generate high energetic consumptions. The solution of the problem is based on replacement...

In the present study explored the effects were obtained for two passive measures: improved thermal insulation and general tightness of the building. Were quantified comparative energy performance for building real reference building, energy efficient building and rehabilitation variants I and II.

It was drawn balance a steam generator. We determined the pollutant emissions from coal combustion in the furnace Jiu Valley steam generator with an output of 150 MW. As an example of the steam generator was considered the type BabkoK Hitachi with turbine Turbao + Atom, in cogeneration.
