Recuperator is a heat recovery system that provides heat transfer from air to air. In other words, the equipment that allows the heat energy contained in the hot gas to pass to a cooler air is called a recuperator. The air flow steamsentering and leaving the recuperator are separated by a wall. As long as the temperature values of the two air flow streams differ from each other, the heat in the warmer air stream is transferred to the cooler air stream through the wall. Thus, heat in hot and dirty air is transferred to cold and clean air, and vice versa. The recuperator investment pays off in a very short time, such as 3-12 months, depending on the capacity, working time and purpose of use.
