Abstract
A single-ended, internally recuperated, radiant tube annulus system in which at least part of the heat recovery takes place within the furnace to which the system is attached and in which the oxidant and/or fuel are preheated not only by heat transfer from the exhaust gases, but also directly from the combustion process. The system includes a plurality of concentric radiant tubular members arranged in a manner providing an outer annular region in which the combustion process is carried out, an inner tubular member through which exhaust gases are exhausted from the system, and intermediate annular regions between the inner tubular member and the outer annular region through which preheated oxidant is provided to the outer annular region for the combustion process. In accordance with one embodiment of this invention, the internal recuperator is used as a fuel reformer.
