Abstract: PROBLEM TO BE SOLVED: To secure a reaction having high selectivity and conversion by providing a source of a 1st gaseous reactant having a specific temp., a mixing chamber, where the reaction does not occur, and a reaction zone, where suffers the gas phase reaction in a reaction device, in the case of forming a uniform gaseous reactant mixture by reacting the 1st gaseous reactant with a 2nd gaseous reactant in the reaction device. SOLUTION: The 1st component in the reaction device is the source of the hot gaseous reactant (reactant A) having a temp. higher than 500 deg.C. The reactant A is injected to a mixing chamber of the reaction device as expansion jet. The expansion jet can be formed by providing an adjuster (such as a flow nozzle) between the hot gas source and the mixing chamber. The 2nd gaseous reactant (reactant B) in one of a gaseous state and a super critical state is injected near a place, where the reactant A is injected. In the mixing chamber, the reactant A and the reactant B does not react with each other substantially, though rapidly mix with each other. Next, the mixture of the reactant A with the reactant B is subjected to gas phase reaction in the reaction zone.

Abstract: Oxygen is lanced into the main combustion reaction of a cement kiln to increase heat transfer to the clinker bed and to increase clinker production. Oxygen is separately lanced along the floor, i.e. the lowest wall of the kiln, to delay mixing with the flame to provide deep staging. The deeply staged oxygen flow is adjusted frequently to control emissions and stabilize the burning zone while the primary oxygen flow is maintained constant.

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 and then combust the fluid.

Abstract: An improved apparatus and method for efficiently processing material, e.g. incinerating waste material, particularly dewatered waste water sludge, in a multiple hearth furnace by injecting high velocity jets of oxygen into the heating or drying zone of the furnace to augment turbulent gas-phase mixing, to aid in the burnout of carbon monoxide and hydrocarbons in the gas phase to achieve lower emissions, to increase convection over the drying sludge to increase its drying rate, and to ignite the drying sludge to further increase its drying rate. The apparatus and method provides an increase in sludge throughput and a reduction in carbon monoxide, nitrogen oxides and hydrocarbon emissions.
