1. A heat-recovering oven system based on temperature gradient, the heat-recovering oven system comprising:

  • multiple chambers arranged in a sequence, the multiple chambers configured for operating at various temperatures according to a temperature gradient arrangement that spans the sequence, wherein each chamber of the multiple chambers includes a cavity defined by walls, wherein each chamber of the multiple chambers further includes an entry and exit opening to pass material through the heat-recovering oven system;

    a conveyor configured for transporting product through the multiple chambers in the sequence for heat treatment according to the temperature gradient arrangement; and

    multiple temperature-segregated heat exchanger systems, the temperature-segregated heat exchanger systems being of different types, each temperature-segregated heat exchanger system including a heat exchanger, a conduit to a plurality of chambers of the multiple chambers based on the temperature of the plurality of chambers in the temperature gradient arrangement, and a return conduit from the a plurality of the chambers of the multiple chambers to the heat exchanger.
