High flow rate gaseous reactant supply

摘要

A gaseous reactant supply apparatus for turning high flow rates of gaseous supply approximately 90 degrees and providing a uniform distribution of gaseous supply. The gaseous supply passes through a venturi throat. Straightening vanes can be positioned inside the venturi throat to reduce rotational motion the gaseous reactant supply may have upon entering the venturi throat. The gaseous reactant supply apparatus exhibits lower pressure drops than exhibited by apparatus of the prior art.
