Abstract
A heat-recovering oven system based on temperature gradient comprises: multiple chambers arranged in a sequence, the chambers configured for operating at various temperatures according to a temperature gradient arrangement that spans the sequence; 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, each heat exchanger system including a heat exchanger, a conduit to at least one of the chambers based on its temperature in the temperature gradient arrangement, and a return conduit from the at least one chamber to the heat exchanger.

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.
A method of recovering heat in an oven system based on temperature gradient, the method comprising:
- setting up multiple chambers in a sequence according to a temperature gradient arrangement that spans the sequence, wherein a conveyor is configured for transporting product through the multiple chambers in the sequence for heat treatment according to the temperature gradient arrangement, wherein each chamber of the multiple chambers is configured to provide a cavity, wherein each chamber of the multiple chambers is further configured with an entry and exit opening to pass the product through the heat-recovering oven system;
- arranging multiple heat exchangers for the oven system, the heat exchangers being of different types;
- and
- grouping the chambers with regard to the heat exchangers based on the temperature gradient arrangement, wherein each heat exchanger is configured to provide a conduit to a grouping of chambers and a return conduit from the grouping of chambers and each heat exchanger is associated with a plurality of chambers of the multiple chambers.
