Hi,
Unfortunately, I cannot add more info: I'm translating a company presentation and in the list of the works carried out on customers' furnaces (a table) there is this entry: the furnace is a float (350 T /D燃煤浮法窑), the work is heat up (烤窑) and as an note they added 九改浮. I think that this furnace was modified into a float during the intervention (the heat up was probably a part of bigger reconstruction works carried out by other companies) and that before it was a 九-something furnace. Hope it can help!

Hello, if you do wanna be helped, please always offer enough context (better in source language) with your question. In fact, enven we Chinese speakers can't figure out the detailed meaning of your "九改浮":-)
