Abstract
A system for recovering clean hot air from a regenerative, glass melting furnace. The furnace, which may be either a side-port or end-port furnace, is constructed in the conventional manner, but a passageway is provided which connects accross the top chambers of the furnace. This passage, at its center, is connected to a heat exchanger, and hot air will pass through the heat exchanger while the furnace is being operated with either side being the firing side while the opposite side is the exhaust side. No valving is necessary to isolate the passage from the exhaust side because of the natural pressure drop existing thereacross.
