[Gasification] Air Inlet Nozzles/Air Flow Ratio

[Mariodg77]

Dear Max, 

I tahk you for the help , but as i can see the pdf version is the same of
the
html verion.
I mean that I've checked and found the same graphics and tables (pg
36,37,38,56,57,58,59).
the graphics have a maximum diameter of the troath (dt) of 300 mm (i need
430 mm)
and also i actually don't know well if 7 nozzles are sufficient or i need
more.
in fact for a dt of 300 mm the book advices 7 nozzles, but for 400 mm or
more 
i suppose they would not be enough..
If i missed something or didn't seen what you're talking about max, please
say to me 
that on Friday night i must go to bed earlyer :P

thanks,

mario
