<p>A method and apparatus for waste heat recovery and reduction in industrial furnaces and heating equipment. The method of heat recovery comprises directing the exhaust gases through a system of channels (8) inside the refractory wall where heat from the flue gases is transferred to the refractory lining and also to the combustion air traveling inside of a heat exchanger (5) also located inside said channels. The high temperature exhaust flue gases traveling along said channels increase the hot face temperature of the refractory wall (7) and reduce the heat flux from the working chamber through the refractory wall. An apparatus for the realization of the heat recovery method includes a flue duct (8) a recuperator (5), hot air piping (6) and a hot air burner (14), all located inside the furnace wall refractory lining (3).</p> |
