Dans une turbine à condensation , on va détente suffisamment pour avoir des gouttes de liquide qui se forme. De très nombreux exemples de phrases traduites contenant turbine vapeur à condensation – Dictionnaire anglais-français et moteur de recherche de traductions anglaises.

Many translated example sentences containing extraction condensation steam turbine – French-English dictionary and search engine for French translations. In condensing turbines , condensation of the exhaust steam is effected by the circulation of large quantities of cold water through the tubes of the condenser. Archives - The Resolute Blog.

Réalisation de trois projets clés novateurs à nos usines de Thunder Bay.

Cycle indirect à condensation. Le caractère corrosif du fluide nécessite la mise en place de deux circuits. Condensation of the steam at low pressure and temperature, followed by the return of condensate to the boiler, completes what is generally known as the steam cycle. The extraction turbine contains two outlets as shown in figure 1. The first outlet extracts the steam with intermediate pressure for the feeding of the heating process while the second outlet extracts the remaining steam with low-pressure steam for the condensation. In these turbines , a portion of steam is bled from intermediate stages to be used by consumers.

The remaining portion of the steam passes the subsequent turbine stages and after that . Pour les turbines à vapeur aptes à la cogénération, on distingue deux types : la turbine à contre pression et la turbine à condensation avec soutirage. Ainsi une certaine qualité de vapeur est mise. Did you know that water droplets traveling at high velocity can take on the force of bullets? It can happen, particularly within steam turbines at a power plant during the process of condensation , where steam transforms back into water.

Moteurs pour les bateaux à vapeur — 621. Eléments de locomotive Châssis, . Données techniques n Puissance : MW max. Changes in the pressure of condensation, however, bring about changes in the temperature of condensation an understanding that the above assumptions hol in the content of liquid . Water is always present in the atmospheric air in the form of vapour.

As air of low temperature expands through the turbine condensation may occur. Condensation gives rise to several problems in materialization of the air cycle as it in temperature rise thus to different conditions than the expected at the turbine exit. Comportement de la vapeur dans une turbine.

Turbine mono-étagée et turbine multi-étagée. Suivi sur un diagramme de Mollier. Mécanisme de la détente : étage à action, à réaction et mixte.

Applications : étude de fonctionnement de turbines industrielles à contre-pression, à condensation , . The approach used in this paper for the condensation of flowing steam is based on the homogeneous condensation of steam and also on the heterogeneous (binary) nucleation of water droplets with a representative chemical. Put the turbine right next to the steam generator. That condensation thing is that water starts to accumulate in the turbine , and thus needs an ejector upgrade to remove it (and send back to the system).

Also, you need a condensator next to the turbine so it can convert exhaust steam into destilled water . EXTRACTION - CONDENSING CHP pmax= 1bar ηsi tmax= 540. Rendement électrique : 20….
