Abstract

See full text

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.
