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. The present invention includes introducing a fourth stream, comprising a first portion of ballast gas, into a fourth conduit, wherein the fourth conduit is concentric with, and surrounding, the first conduit, the second conduit, and the third conduit. The present invention includes introducing a fifth stream, comprising a second portion of ballast gas, into a fifth conduit, wherein the fifth conduit is concentric with, and surrounding, the first conduit, the second conduit, the third conduit and the fourth conduit.
