Abstract
A system for preheating air being fed to a continuous fired furnace by means of high temperature waste gases exhausted from the furnace. The system includes two pairs of interconnected regenerators. The regenerators of one pair are alternately connected by means of a reversing valve to an ambient air inlet and a waste gas exhaust stack, and the regenerators of the other pair are alternately connected by means of a second reversing valve to the furnace's waste gas outlet duct and combustion air inlet duct.
