[Gasification] Air Inlet Nozzles/Air Flow Ratio

[Mariodg77]

dear forum,

studying the fao's book (woodgas as an engine fuel) i'm understanding a lot
of things....

now, trying to make calculations about the plant in Loma Plata, i see that
the graphs to calculate the dimensions of the air inlet nozzles depending on
the throat diameter (from which depends the diameter of the fire box, the
Ratio between nozzle flow area and throat area, the nozzle top ring diameter
ecc ...  
http://www.fao.org/documents/show_cdr.asp?url_file=/DOCREP/T0512E/T0512e00.htm
)
have a maximum value for the troath diameter of 300 mm .

i estimated a throath diameter for a single gasifier in loma plata of about
4300 mm.
how can i calculate the values of inlet nozzles? (read also how can i
calculate the air flow ratio in a single gasifier?)

can someone suggest me more detailed graphs? 

thanks,

mario
