Patent ID: 8827691

Claim:
A method of distributed combustion comprises the steps of: a first jet of combustion reactants comprising a primary portion of an oxidant and a primary portion of a fuel is injected from a fuel-oxidant nozzle into a combustion space, wherein either the primary portion of oxidant enshrouds the primary portion of fuel or the primary portion of fuel enshrouds the primary portion of oxidant; a second jet of a secondary portion of one of the combustion reactants is injected from at least one dynamical lance into the combustion space, the combustion reactant of the second jet being the same as the combustion reactant that is injected annularly around the other combustion reactant in the first jet; a third jet of actuating fluid is injected close to the second jet to cause the second jet to be bent towards the first jet, wherein: if the second jet is of oxidant, after injection of the second jet is initiated, the primary portion of oxidant is decreased, the secondary portion of oxidant is increased until a desired degree of staging of overall oxidant between the primary and secondary portions is achieved, and the desired degree of staging is achieved when the secondary portion of oxidant makes up 90-95% of a total amount of the overall oxidant injected; and if the second jet is of fuel, after injection of the second jet is initiated, the primary portion of the fuel is decreased, the secondary portion of the fuel is increased until a desired degree of staging of overall fuel between the primary and secondary portions is achieved, and the desired degree of staging is achieved when the secondary portion of fuel makes up 90-95% of a total amount of the overall fuel injected.
