Patent ID: 6841134

Claim:
A chemical process reactor for processing an industrial gas flow through the application of heat, comprising: a. a housing having at least one gas flow inlet for receiving said industrial gas flow, and at least one outlet; b. a gas flow channel within said housing, and an array of current-carrying wire screen element packets connected between respective conductor blocks, said conductor blocks forming outside walls of said channel and said packets positioned at spaced apart intervals across said channel from a first position proximate said outlet and a second position internal to said housing; c. a plurality of passages through said conductor blocks, having respective inlet openings in flow communication with said at least one gas flow inlet, and having respective outlet openings proximate said second position of said channel; d. said array further comprising a first electrical bus connected to a respective first conductor block proximate said outlet, and a second electrical bus connected to a respective last conductor block proximate said second position, each of said conductor blocks being electrically isolated from other conductor blocks, and each of said screen element packets having a first termination connected to a conductor block on one side of said channel and having a second termination connected to a conductor block on the other side of said channel, whereby a series electrical path is created from said first electrical bus through respective conductor blocks and screen element packets to said second electrical bus; e. a first conductor connected to said first electrical bus and projecting externally of said housing, and a second conductor connected to said second electrical bus and projecting externally of said housing; and f. a pair of expansion joints respectively attached to said housing, each of said expansion joints having a movable end connected to one of said first or second conductors.
