Title (EN) HEAT RECOVERY DEVICE
(FR) DISPOSITIF DE RÉCUPÉRATION DE CHALEUR
(ZH) 回热设备
Abstract:
(EN) A heat recovery device, which comprises a primary steam pipe (2), an ancillary pipe (01), a water-feeding heater, and a steam-side regulation valve (02) that is provided on the ancillary pipe (01), wherein the steam-side regulation valve (02) is configured to regulate the primary steam in the ancillary pipe (01) so as to control the steam extraction pressure behind the stream-side regulation valve (02) so that the exit temperature of the water-feeding heater is controlled, thereby reaching a pre-set water-feeding temperature.
(FR) L'invention concerne un dispositif de récupération de chaleur comprenant un tuyau de vapeur primaire (2), un tuyau auxiliaire (01), un dispositif de chauffage d'alimentation en eau, ainsi qu'une vanne de régulation côté vapeur (02) disposée sur le tuyau auxiliaire (01), ladite vanne (02) étant configurée pour réguler la vapeur primaire dans le tuyau auxiliaire (01) de sorte à réguler la pression d'extraction de vapeur derrière la vanne de régulation côté vapeur (02) afin que la température de sortie du dispositif de chauffage d'alimentation en eau soit régulée, ce qui permet d'atteindre une température d'alimentation en eau prédéfinie.
(ZH) 一种回热设备,该设备包括主蒸汽管道(2)、附加管道(01)、给水加热器以及设置在所述附加管道(01)上的汽侧调节阀(02),所述汽侧调节阀(02)设置为对所述附加管道(01)中的主蒸汽进行调节,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的出口温度,以达到预设给水温度。
