A catalytic reformer includes a reformer vessel defining an interior plenum housing at least one reactor tube assembly having a catalyst bed. The reformer also includes a burner gas inlet for providing hot burner gas to heat the reactor tubes, and a burner gas outlet. A burner gas guide sleeve is disposed substantially coaxially around at least a portion of the reactor tube assembly, defining an annular burner gas passage. A burner exhaust gas collection assembly connects the burner gas guide sleeve to the burner gas outlet.
