Abstract: A system for combusting difficult to combust fluid such as waste fluid wherein fuel and gaseous oxidant combust in a hot combustion gas chamber to form a hot combustion gas mixture which is accelerated to a high speed and at a steady, i.e. non-pulsing, flow is then used to atomize and then combust the fluid.

Abstract: A system for establishing a single coherent gas jet from a plurality of initial gas jets ejected from a single lance wherein the initial gas jets are themselves coherent, are angled inward, and are surrounded by a flame envelope. The initial coherent gas jets merge to form a single coherent jet and the gases of the initial gas jets do not substantially interact within this single coherent jet for the length of the resulting single coherent gas jet.

Abstract: A system for providing gases (1) into an injection volume in one or more coherent gas jets (30) proximate to one or more turbulent gas jets (32) wherein a coherent gas jet is formed in a forming volume (5) with a flame envelope (31) prior to passage into the injection volume into which the turbulent gas jets are directly passed.

Abstract: An arrangement wherein a coherent jet (62) is established proximate to a powder injection system and the coherent jet not only provides for gas delivery but also serves to improve the efficiency of the delivery of powder from the powder injection system. The arrangement provides in forming a flame envelope (63) around both the gas stream (62) and the powder mixture stream (67) delivered to a liquid, e.g. molten metal (65), from a gas jet nozzle (5,61) and a lance passage (66) for powder and carrier gas injection.

Abstract: The invention comprises a reactor having a source of a first hot reactant gas, a mixing chamber in which said first hot reactant gas mixes with a second reactant gas to form a reactant gas mixture, but wherein substantially no reaction takes place and a reaction zone wherein said mixture undergoes vapor phase reaction. A process for using the reactor is also disclosed.

Abstract: A lance which may be used to establish a long coherent gas jet which includes a primary passageway having a converging/diverging nozzle, and two radially spaced secondary passageways for establishing a flame barrier, each of the passageways communicating with an injection space defined by a protective jacket. Additional to these main passageways the jacket may comprise one or two other passages for the supply of fluid or solid streams.
