a It will be assumed that, owing to the velocity of blast, the admixture of inert gases from zones 

 below, and the low temperatures of zones above, this COa escipes reduction to CO. 



b It will be assumed, for the reasons stated under zone 570°, thai only J of the COa driven ofif here 

 is reduced lo CO iu upper zone 57u°.
