ABSTRACT:
This disclosure teaches a heater which is especially well suited to handle large flows of a process stream at low pressure losses. A cylindrical sleeve is mounted by means of a bellows inwardly of a cylindrical shell to separate an inner hot gas flow space from an annular outer process flow space. The sleeve encloses an entrance combustion zone and has an exit end. A baffle is mounted inwardly of the sleeve with a closed end projecting into the exit end of the sleeve to channel the hot gas into an annular convection space bordered outwardly by the sleeve. Extended surface projects from the sleeve into the process flow space and additional extended surface projects from the sleeve into the convection space.
