A heat treatment device includes: a heat treatment chamber which accommodates an object to be treated; a cooling gas supply unit which supplies a cooling gas into the heat treatment chamber; a cooling gas circulation unit which circulates the cooling gas in the heat treatment chamber; and a gas purge unit which gas-purges, with an inert gas, a portion in which there is a possibility of mixing of the cooling gas supplied into the heat treatment chamber and an oxygen gas, in which the cooling gas supply unit supplies a hydrogen gas into the heat treatment chamber as the cooling gas.

Heat shrink wrap product packaging oven or tunnel apparatus and processing methods are provided which incorporate or utilize airfoils in conjunction with hot air-providing side walls to desirably control impact of hot air onto a product wrapped with a tube of heat shrink wrap film and being conveyed on a conveyor thereby. In such heat shrink wrap product packaging apparatus and methods, such airfoils can be movable, e.g., rotatably moveable, relative to the side walls to vertically alter an air impact point onto the product.

Techniques regarding a fan friction oven are provided. For example, one or more embodiments described herein can regard an apparatus comprising a processing chamber in fluid communication with a heating blower and a circulation blower. The heating blower can heat air adjacent to the processing chamber by fan friction. Also, the circulation blower can circulate the air heated by the heating blower into the processing chamber.

A heat-treating furnace has: a rotary shaft; a rotary bottom surface pivotally supported by the rotary shaft and rotates; a plurality of workpiece storage chambers arranged on the rotary bottom surface in a multi-stage torus configuration around an axis of the rotary shaft as a center; a hollow bell-shaped hot-blast guide disposed in a center of the torus configuration on the rotary bottom surface around the axis of the rotary shaft as a center so as to decrease a volumetric capacity in the furnace and to adjust a quantity of a hot blast fed in from above itself into the workpiece storage chamber on each stage; a furnace body bottom surface spaced away from the rotary bottom surface; and a furnace body lateral surface disposed on the furnace body bottom surface.

A shuttle kiln (100) according to certain aspects includes at least one flue channel (124) and multiple flue risers (122) in fluid communication with the flue channel (124), and at least one shuttle (104) defining multiple exhaust shafts (140) arranged above the multiple flue risers (122), wherein an aggregate volume of a first exhaust shaft/riser pair (140-1, 122-1) differs from an aggregate volume of a second exhaust shaft/riser pair (140-2, 122-2). Such configuration at least partially compensates for different backpressures that would otherwise be experienced by flue gas exiting a shuttle kiln cavity (138) through different exhaust shafts (140), thereby improving uniformity of flue gas flow and reducing temperature variability within a kiln cavity (138).

A modular industrial energy transfer system includes a shell and at least one energy transfer unit coupled to the shell. The shell includes a plurality of sidewalls, a ceiling member coupled thereto, and a plurality of mounting structures disposed along the shell. The plurality of sidewalls and the ceiling member cooperate to define an interior volume to accommodate a work product. The at least one energy transfer unit is coupled to the shell via at least one of the plurality of mounting structures and is partially disposed through the shell to generate an airflow pattern through the interior volume of the shell.
