Title (EN) COMBINED REGENERATION DEVICE
(FR) DISPOSITIF DE RÉGÉNÉRATION COMBINÉ
(ZH) 联合回热设备
Abstract:
(EN) A combined regeneration device, comprising: a high pressure cylinder (4) of a steam turbine; a main steam pipe (2); a final stage extraction steam pipe (10); an additional pipe (01) added to the main steam pipe (2); a heat exchanger (03), in which the main steam in the main steam pipe (2) is used as a heat source; a feed water heater (05), in which the exhaust steam from the heat exchanger (03) is used as a heat source; and a steam side regulation valve (02) provided on the additional pipe (01). The combined regeneration device is configured to adjust the main steam in the additional pipe (01), such that the pressure of the extraction steam behind the steam side regulation valve (02) can be controlled to control the outlet temperature of the feed water heater (05) to reach a preset feed water temperature.
(FR) Dispositif de régénération combiné, comprenant : un cylindre haute-pression (4) d'une turbine à vapeur ; un tuyau de vapeur principale (2) ; un tuyau de vapeur d'extraction d'étage final (10) ; un tuyau supplémentaire (01) ajouté au tuyau de vapeur principale (2) ; un échangeur de chaleur (03), dans lequel la vapeur principale dans le tuyau de vapeur principale (2) est utilisée comme source de chaleur ; un chauffe-eau d'alimentation (05), dans lequel la vapeur d'échappement provenant de l'échangeur de chaleur (03) est utilisée comme source de chaleur ; et une soupape de régulation côté vapeur (02) disposée sur le tuyau supplémentaire (01). Le dispositif de régénération combiné est conçu pour régler la vapeur principale dans le tuyau supplémentaire (01), de telle sorte que la pression de la vapeur d'extraction derrière la soupape de régulation côté vapeur (02) peut être commandée pour commander la température de sortie du chauffe-eau d'alimentation (05) pour atteindre une température d'eau d'alimentation prédéfinie.
(ZH) 一种联合回热设备,包括汽轮机的高压缸(4),主蒸汽管道(2),末级抽汽管道(10),所述主蒸汽管道(2)上增设的附加管道(01),以所述主蒸汽管道(2)中的主蒸汽为热源的换热器(03),以所述换热器(03)的排汽为热源的给水加热器(05),设置在所述附加管道(01)上的汽侧调节阀(02),设置为对所述附加管道(01)中的主蒸汽进行调节,可以控制所述汽侧调节阀(02)后的抽汽压力来控制所述给水加热器(05)的出口温度,以达到预设给水温度。
