ABSTRACT:
A recuperator structure for recovering heat values from a hot gas stream comprising exhaust gases from a combustion burner supplied with combustion air for burning a fuel in which a heat exchanger is used for exchanging heat between the hot exhaust gases and the combustion air for preheating the combustion air and including a variable temperature control for selectively restricting the volumetric flow of either the air or the exhaust gases or both through the heat exchanger in order to control the temperature in the heat exchanger.
One of the features of this invention is to provide a recuperator structure for recovering heat values by extracting heat in a heat exchanger from the hot exhaust gases from a combustion burner and using this heat in the exchanger to preheat the combustion air to the burner and including means for controlling the temperature in the heat exchanger by controlling the volumetric flow of either the combustion air or the exhaust gases or both through the heat exchanger.
