Abstract: A method for producing usable product in a reactor including introducing a viscous mixture including usable product and unconverted reactant into a chamber of a housing through an inlet, wherein the mixture has a temperature greater than ambient temperature when introduced into the chamber; heating the viscous mixture in the chamber using at least one of an induction heater, an exothermic reaction, a microwave heater, a radio frequency heater, an electrical resistance heater, a laser heater, a plasma heater, and a heated fluid; converting at least a portion of the unconverted reactant to usable product, wherein at least a portion of the usable product is produced in the viscous mixture; and transferring the viscous mixture including usable product from the housing through an outlet.

Abstract: A reagent injection system for a catalytic emissions reduction assembly of a combustion turbine that includes an exhaust duct and at least one injector. The exhaust duct includes a first section including an entrance end and an exit end, wherein the entrance end is configured to be fluidly coupled to the combustion turbine to receive exhaust gases therefrom. The exhaust duct also includes and a second section having an entrance end that is fluidly coupled to the exit end of the first section. The at least one injector is operatively coupled to one of the first and second sections, and each injector is configured to inject a reagent into the exhaust gases flowing through the exhaust duct.

Abstract: A classifier including a housing, a body, a vane assembly, and an outlet. The housing extends along a longitudinal axis between opposing first and second ends, and includes a lower portion provided at the first end and including an inlet, an upper portion provided at the second end and including a reclaim outlet, and an intermediate portion provided between the upper and lower portions. The body is disposed within the housing that defines a chamber therebetween. The vane assembly includes a plurality of blades and is provided between an outer surface of the body and an inner surface of the intermediate portion dividing the chamber into first and second chambers. The outlet is provided at the second end and is fluidly connected to the second chamber to allow fine particles separated from coarse particles to flow through the outlet. The reclaim outlet is fluidly connected with the second chamber and a pulverizer to allow coarse particles separated from the fluid flow to be directed back to the pulverizer.

Abstract: A method for producing a usable by-product in a cyclone reactor. The method comprises introducing a reactant into a housing of the reactor through an inlet; using a burner to combust a first portion of the reactant in an exothermic reaction provided in a flame zone near a center of the housing; consuming a second portion of the reactant in an endothermic reaction near an outer wall of the housing to produce the by-product as part of a slag layer; and removing the slag layer including the by-product though an outlet in the housing; wherein the endothermic reaction takes place at a temperature of at least 1600° C.

Abstract: A process for producing a usable product in a reactor comprising introducing co-reactants comprising a fuel source and oxygen into a first section through an inlet, the fuel source comprising carbon; combusting at least a portion of the fuel source and oxygen in an exothermic reaction in the first section using a burner; transferring the co-reactants through a second section that includes a throat having a size that is smaller than a size of the first section, such that a vacuum is induced and a velocity of the co-reactants increases; transferring the co-reactants into a third section that is downstream from the throat and includes an inner wall having a size that is greater than the size of the throat; depositing at least a portion of the uncombusted carbon and a metal oxide along the inner wall, wherein the metal oxide is introduced into at least one of the sections; converting the deposited metal oxide into the usable product in a carbothermic reduction reaction within a molten slag along the inner wall at
