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: 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 establishing a plurality of coherent gas jets (20) proximate one another using a single lance (1) wherein a plurality of gas jets (20) are ejected from a corresponding plurality of nozzles (3) in a lance (1) and a flame envelope (21) is established around the plurality of gas jets (20), and the jets remain distinct and do not coalesce for their length.

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.

Abstract: A method for introducing gas into a liquid wherein a gas stream is ejected from a lance spaced above the liquid surface and directed from the lance onto the liquid surface. The gas retains substantially all its original jet axis velocity when it contacts the liquid surface, and substantially all of the gas penetrates the liquid surface and is introduced into the liquid. Preferably the gas stream is surrounded by a flame envelope running from the lance to the liquid surface, which shields the gas from ambient gas entrainment. The gas stream preferably forms a gas cavity within the liquid having a diameter substantially the same as the diameter of the gas stream as it is ejected from the lance.

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 system for combusting difficult to combust fluid such as waste fluid (8) wherein fuel (1) and gaseous oxidant (4) combust in a hot combustion gas chamber (3) to form a hot combustion gas mixture which is accelerated to a high speed and at a steady, i.e. nonpulsing, flow is then used to atomize an d then combust the fluid.
