Abstract: An improved method and apparatus for burning leaner lean wet gas wherein the gas is mixed with an oxidant gas and uniformly distributed to the face of a burner assembly composed of a plurality of parallel positioned, spaced-apart elongated members, defining a plurality of relatively narrow slots through which the gas mixture flows and igniting the gas mixture as it exits from these slots. This improved burner can be used in the manufacture of certain grades of carbon black to provide heat to the carbon black pellet dryer by burning the by-product gases produced in the carbon black reactor.

Abstract: A method of producing carbon black including the steps of burning hydrocarbon fuel, introducing a hydrocarbon feedstock into the combustion gases, quenching the carbon black and gases formed, pelletizing the carbon black with water, drying the pellets with a purge gas and injecting a controlled amount of an oxidant gas into the substantially dry pellets to reduce their modulus-producing properties without reducing their abrasive resistance producing properties and the apparatus therefore.
