Classification: CPC C  F | IPC C  F

Claim 0:
1. A preheater comprising:
a central inlet configured to receive reactant gases;
a circuitous gas flow path directly downstream of the central inlet defined by a plurality of baffles, wherein:
a first portion of the plurality of baffles extend from a first surface,
a second portion of the plurality of baffles extend from a second, opposite surface,
the first portion of the plurality of baffles and the second portion of the plurality of baffles interleave to increase a dwell time of reactant gases passing through the circuitous flow path;

a plenum section downstream of the circuitous gas flow path configured to at least partially equalize the static pressure across an outlet diffuser plate downstream of the plenum section; and
the outlet diffuser plate, wherein the outlet diffuser plate defines a plurality of apertures fluidly configured to couple the preheater to a furnace working zone,
wherein the circuitous gas flow path is fluidly coupled to the plenum section by an outer circumferential slot opening.
