Abstract

A method of and system for recirculating a fluid in a particle production system. A reactor produces a reactive particle-gas mixture. A quench chamber mixes a conditioning fluid with the reactive particle-gas mixture, producing a cooled particle-gas mixture that comprises a plurality of precursor material particles and an output fluid. A filter element filters the output fluid, producing a filtered output. A temperature control module controls the temperature of the filtered output, producing a temperature-controlled, filtered output. A content ratio control module modulates the content of the temperature-controlled, filtered output, thereby producing a content-controlled, temperature-controlled, filtered output. A channeling element supplies the content-controlled, temperature-controlled, filtered output to the quench chamber, wherein the content-controlled, filtered output is provided to the quench chamber as the conditioning fluid to be used in cooling the reactive particle-gas mixture.
