ABSTRACT:
An apparatus for reducing hydrocarbon fuel requirements for Haber Ammonia Synthesis by the supply of selected gases to the second reformer of such system, comprising a first cylindrical conduit, a second smaller coaxial cylinder inside of the first conduit, forming a first annular space therebetween, the downstream end of said second conduit closed, and a plurality of circumferentially-spaced orifices in the wall of said conduit upstream of the closed end. Means to supply air at selected pressure P1, temperature and flow rate to the first annular space, means to supply at least methane at a pressure P2 greater than P1, to said second conduit, so that the concentration of methane in the air will be less than the lower explosive limit, and means to shield the jets of gas from the orifices in the second conduit, as they flow radially outwardly across the annular space. Means are also provided for adding steam in selected ratio with the methane prior to flow into the second conduit, whereby air, methane and steam are mixed together prior to flow into the second Haber reformer.
