Reducing the environmental impact of a gas operated cogeneration installation

Abstract

Abstract. The paper deals with a case study for carried out in order to justify the installation of a gas cogeneration system fitted with an internal combustion engine, system used to supply electricity and heat to the users of an energy user which exceeds 1000 toe/year. 2 scenarios were therefore compared based on the energetic analysis: -the actual scenario in which energy is supplied from the National Energetic System. -the scenario in which a combined heat and power plant is used. The amount of energy saved yearly, the specific fuel consumption and the environmental impact were determined by the comparative study. The diagrams representing the variation of the performance indicators according to the operation period were also created. The usefulness of the paper consists in the creation of the yearly optimum installation operation time chart.

Monitoring the noise level around the Jiu Valley mines using Bruel&Kjaer noise dose meter type 4448

“…During the Middle Ages, the inhabitants of the Jiu Valley lived in huts spread along the mountains, and often near the river, and the main activity was shepherding.
