to counter the potential flow (转帖)? 关于煤气化中的,有这么一段, Consideration should be given by the contractor as to whether this rotary valve requires purge gas (eg.Recycled Sysgas) to counter the potential flow of gas from the Gasifier into the Main Dryer cyclone system. 可是怎么也搞不懂 这个 to counter the potential flow 是什么意思? 原帖地址: [url=http://www.hgbbs.net/bbs/thread-130998-1-1.html]http://www.hgbbs.net/bbs/thread-130998-1-1.html [/url]查看更多2个回答 . 2人已关注
