Abstract: The present invention is a method of combustion of a solid fuel stream with oxygen. The present invention includes introducing a first stream, comprising a first portion of substantially pure oxygen, into a first conduit. The present invention includes introducing a second stream, comprising a solid fuel stream and a conveying media, into a second conduit, wherein the second conduit is concentric with, and surrounding, the first conduit. The present invention includes introducing a third stream, comprising a second portion of substantially pure oxygen, into a third conduit, wherein the third conduit is concentric with, and surrounding, the first conduit and the second conduit. The present invention includes igniting the first stream, the second stream, and the third stream as they exit the first conduit, the second conduit and the third conduit, in such a way as to create a flame.

Abstract: This disclosure discusses sanitizing objects using a combination of an antimicrobial treatment and a quick freeze step. The use of antimicrobial agents for disinfecting food products often raises food quality and safety issues. The present invention uses hurdle technology to disable target microorganisms by using an antimicrobial agent, such as ozone, to make the targeted microorganisms more susceptible to the stresses of a rapid-freeze process and to lower the microbial resistance to freezing in general. Thus, it is more difficult for microorganisms to recover and reactivate during a subsequent thawing process. Hurdle technology allows low-levels of anti-microbial agents to be used to enable the use of rapid freezing for preserving foods. Novel antimicrobial hurdles coupled with conventional rapid freeze processes preserves food freshness, color, and taste while providing effective sanitation of food and non-food objects.
