1. A method for operating a pyrolysis reactor, comprising:
supplying a first amount of fuel and oxidant within a fuel/oxidant equivalence ratio range into a combustion chamber and combusting the first amount of fuel and oxidant to produce a combustion product; supplying a feedstock and the combustion product into a mixing chamber, wherein the combustion product mixes with the feedstock and the feedstock is decomposed into reaction products including hydrogen and carbon in a pyrolysis operation;
monitoring production of the carbon and hydrogen during the pyrolysis operation;
supplying a second amount of oxidant into the mixing chamber when the monitored carbon and hydrogen production is outside a target carbon and hydrogen specification, and reacting the supplied oxidant with carbon attached to walls of the mixing chamber; and
supplying a third amount of fuel and oxidant into the combustion chamber at a rich fuel/oxidant ratio above the fuel/oxidant equivalence ratio range when only the monitored carbon production is outside a target carbon specification and combusting the third amount of fuel and oxidant to produce the combustion product and soot; supplying the feedstock, the combustion product and the soot into the mixing chamber, wherein the combustion product and soot mix with the feedstock, and the feedstock is decomposed into the reaction products in a pyrolysis operation and the soot seeds carbon formation.
