Title
(EN) RANKINE CYCLE DEVICE
(FR) DISPOSITIF DE CYCLE DE RANKINE
Abstract
(EN)
An expansion ratio of steam sucked and exhausted by an expander (4) is set to a specified expansion ratio (e) according to the specified relationship between the pressure (Pevp) and the temperature (Tevp) of steam sucked by the expander (4) provided with a front-stage cylinder room and a rear-stage vane room that are serially arranged, thereby making the pressure (Pexp2) and the temperature (Texp2) of steam exhausted from the expander (4) agree with target values to thereby deliver maximum performances of the expander (4) and a condenser (5). Since steam in the front-stage cylinder room is in a superheated steam area and does not contain water, no water hammering occurs in the cylinder room. In addition, steam at the outlet of the vane room is in a saturated steam area and contains water, the water can be used to lubricate and seal the vane room.
(FR)
On fixe un taux de détente d'une vapeur aspirée et évacuée par un détendeur (4) à un coefficient de détente déterminé ($g(e)) selon la relation déterminée entre la pression (Pevp) et la température (Tevp) de la vapeur aspirée par le détendeur (4) muni d'une chambre de cylindres d'étage avant et d'une chambre d'aubes d'étage arrière disposées en série, permettant ainsi à la pression (Pexp2) et à la température (Texp2) de la vapeur évacuée à partir du détendeur (4) de correspondre à des valeurs prédéterminées permettant ainsi d'obtenir des rendements maximaux du détendeur (4) et du condenseur (5). Etant donné que la vapeur dans la chambre de cylindres d'étage avant constitue une zone surchauffée et ne contient pas d'eau, il n'y a aucun effet de marteau dans la chambre de cylindres. Par ailleurs, la vapeur à la sortie de la chambre d'aubes se trouve dans une zone saturée de vapeur et contient de l'eau, l'eau peut être utilisée pour la lubrification et l'étanchéité de la chambre d'aubes.
