1. A multi-tubular chemical reactor comprising:
a plurality of spaced-apart reactor units aligned in a single row or parallel rows of essentially identical configuration aligned along a common longitudinal axis corresponding to line L of length X, line L extending from the first to the last reactor disposed within a row, each reactor unit in a row comprising an elongate tube having a wall with internal and external surfaces, an inlet at one end and an outlet at the opposing end, the wall enclosing a gaseous flow passageway at least a portion of which defines a gas phase reaction zone; and
at least one igniter for the initiation of a plurality of gas phase exothermic reactions within the gas phase reaction zones of the reactor units, the igniter including a radiant heat-producing element positioned in proximity to, but in physical isolation from, exposed sections of reactor units, the length of such heat-producing element extending from at least about 30 percent up to about 100 percent of length X of line L.
