✦ Synopsis

The Addition of Air in Stages to a Perfectly Stirred Reactor

SEVE~a~ investigators have studied premixed combustion systems in order to determine optimum combustion intensities and minimum volumes for completion of the reaction under various conditions. Examples of this work may be found in references 1 to 6. In this Department we are attempting to find the ideal conditions for each individual part of a combustion system so that in the design of a practical system the nearest possible approximations to these optimum conditions may be made. The present note describes a theoretical attempt to discover the optimum mixing conditions for fuel, air, and recirculation products in a non-premixed system. Experimental studies on a one-dimensional flame are being made by Datschefski.

The system theoretically studied here is one in which all the fuel and recirculation products enter Zone 1 of a six-zone reactor along with a proportion of the air, the rest of the air being added to the other five zones (Figure ). The volume required in a reactor of this type to burn one pound of fuel is compared with that of a homogeneous reactor.
