Abstract:
1. A method of performing distributed combustion, comprising the steps of: injecting fuel into a furnace along a fuel injection axis from a fuel nozzle disposed in a burner block, an axis of the fuel nozzle being a fuel injection nozzle; injecting primary oxidant into the furnace from a primary oxidant nozzle, the fuel and primary oxidant nozzles being concentrically disposed with respect to one another; combusting the fuel and primary oxidant in the furnace; injecting first and second jets of secondary oxidant into the furnace from first and second dynamical lances disposed on opposite sides of the fuel nozzle in the burner block; decreasing an amount of the primary oxidant injected from the primary oxidant nozzle as an amount of the secondary oxidant injected as the first and second jets of secondary oxidant is increased; and injecting first and second jets of actuating fluid at angles to the first and second jets of secondary oxidant, respectively, such that the first and second jets of secondary oxidant are fluidically angled away from the fuel injection axis.
