    Abstract: During a heating phase, injection of a jet of fuel and oxidant (fuel annularly enshrouding oxidant or oxidant annularly enshrouding fuel) from a fuel-oxidant nozzle is combusted in a combustion space. During a transition from the heating phase to a distributed combustion phase, an amount of a secondary portion of either the fuel or oxidant is injected as a jet into the combustion space while the primary portion of that same reactant from the fuel-oxidant nozzle is decreased. At some point during the transition phase, a jet of actuating fluid is injected at an angle towards the jet of reactants from the fuel-oxidant nozzle and/or towards the jet of the secondary portion of reactant. The jet of primary portions of reactants and/or secondary portion of reactant is caused to be bent/deviated towards the other of the two jets. The staging of the secondary portion of reactant is increased until a desired degrees of staging and commencement of a distributed combustion phase are achieved.

    Abstract: A burner recessed from a combustion space in a burner block adjacent the combustion space injects a secondary reactant (a second portion of a first reactant) around and upstream of a stream of a primary reactant (a first portion of the first reactant) and a stream of a second reactant in order to prevent or inhibit deposition of material from recirculating gases in the combustion space upon the burner. The first reactant is one of a fuel and an oxidant while the second reactant is the other of a fuel and an oxidant. The secondary stream may be injected from a continuous annulus formed in an outer body of the burner or from a plurality of radially spaced holes formed in the outer body. The primary stream is injected from one of an inner bore formed in an inner body of the burner and a reactant annulus defined between the inner and outer bodies while the second reactant is injected from the other of the inner bore and the reactant annulus.

    Abstract: During a heating phase, injection of a jet of fuel and oxidant (fuel annularly enshrouding oxidant or oxidant annularly enshrouding fuel) from a fuel-oxidant nozzle is combusted in a combustion space. During a transition from the heating phase to a distributed combustion phase, an amount of a secondary portion of either the fuel or oxidant is injected as a jet into the combustion space while the primary portion of that same reactant from the fuel-oxidant nozzle is decreased. At some point during the transition phase, a jet of actuating fluid is injected at an angle towards the jet of reactants from the fuel-oxidant nozzle and/or towards the jet of the secondary portion of reactant. The jet of primary portions of reactants and/or secondary portion of reactant is caused to be bent/deviated towards the other of the two jets. The staging of the secondary portion of reactant is increased until a desired degrees of staging and commencement of a distributed combustion phase are achieved.
