Based on normal ash rate at 48 deg C water inlet temperature and maintaining the bath at 60 deg C, 25m3/hr of water is required to maintain the bath temperature. 正常出力时，入水温度是 48 C，维持槽体内水温 60 C所需流量是 25m3/小时 2. Based on maximum ash rate at 48 deg C water inlet temperature and maintaining the bath at 80 deg C, 96m3/hr of water is required to maintain the bath temperature. 在最大出力时，入水温度是 48 C，维持槽体内水温 80 C所需流量是 96m3/小时 The ining water supply should allow for the variation in water required in the range of 50m3/hr 150m3/hr. 入水流量应在 50m3/小时 150m3/小时范围内变动 . Seal Trough Flushing水封槽冲洗水 The separate supply for seal trough flushing of barg should allow for a maximum of 100m3/hr supply. 单独供给的水封槽冲洗水 barg允许的最大供给流量是 100m3/小时。 Buyer : Guangdong Guohua Yeudian Taishan Electric Power Plant Project : Taishan Power Plant Phase I 3 x 600MW CBMH Project No. C6196 Contract No. 2020RCC/13069UK Document No. C6196/MM/1 Operating and Maintenance Instructions 12 SECTION 2 第二部分 FUNCTIONAL DESIGN SPECIFICATION 功能设计说明 Buyer : Guangdong Guohua Yeudian Taishan Electric Power Plant Project : Taishan Power Plant Phase I 3 x 600MW CBMH Project No. C6196 Contract No. 2020RCC/13069UK Document No. C6196/MM/1 Operating and Maintenance Instructions 13 Project : Guangdong Guohua Yuedian Ta。
