A catalytic reformer (10) includes a reformer vessel (14) defining an interi or plenum (15) housing at least one reactor tube (30, 130) assembly having a catalyst bed (135). The reformer also includes a burner gas inlet (16) for providing hot burner gas to heat the reactor tubes (30), and a burner gas outlet (60). A burner gas guide sleeve (20) is disposed substantially coaxially around at least a portion of the reactor tube assembly (30), defining an annular burner gas passage (22). A burner exhaust gas collection assembly (64) connects the burner gas guide sleeve (20) to the burner gas outlet (60).
