A CRT exhaust oven for heat-treating CRTs includes an oven housing, a baffle structure accommodated in the oven housing for circulation of atmosphere within the oven housing, and a plurality of exhaust carts capable of travelling below the oven housing. Each of the exhaust carts is provided with two exhaust heads having different heights aligned in the direction of travel of the exhaust carts so that there is no clearance, as viewed from above, between two adjoining CRTs mounted on respective exhaust heads of each exhaust cart. Each of the exhaust carts travels intermittently below the oven housing. The baffle structure has a large number of upper and lower holes formed on respective sides thereof in the direction of travel of the exhaust carts. The atmosphere introduced inside the baffle structure through the lower holes is directed to funnel portions of the two adjoining CRTs having different heights whereas the atmosphere introduced inside the baffle structure through the upper holes is directed to panel portions of the two adjoining CRTs.
