A heating system for heating composite materials includes a housing defining a cavity therein, a vertical conveyor system provided in the cavity of the housing for moving objects through the housing, and a heating arrangement provided in the housing for heating the objects that are moved through the housing. The heating arrangement may include at least one heating element provided in at least one of an upper portion of the housing and a lower portion of the housing. The heating arrangement may include at least one fan to circulate heated air generated by the heating arrangement throughout the cavity of the housing.

There is disclosed a vertical vibratory thermal treatment system, comprising a heating section for thermally treating material, a retort section that is located within or connected to the heating section and includes at least one elevator system for vertically moving the material to the heating section. The disclosed elevator system is isolated from other parts of the thermal treatment section by an enclosure thereby allowing for flexibility and simplicity in the design of the retort section. There is also disclosed a method of treating materials, including hazardous or radioactive materials, such as a powder, sand, granule, gravel, agglomerate or other form of particle or combinations thereof, using the system described herein.

A method of thermal processing a work piece using another work piece which includes providing a chamber having a plurality of temperature zones, disposing a first work piece within a first temperature zone of the chamber, allowing a temperature of the first work piece to thermally equilibrate with the first temperature zone, moving the first work piece to a second temperature zone and disposing a second work piece within the second temperature zone of the chamber, in fluid communication with the first work piece, wherein a thermal exchange occurs between the first and second work pieces.

The invention relates to a multi-level furnace for thermal treatment of the material flow which has at least two process chambers arranged one above another, each providing at least two level floors, and is equipped with one or more transfer devices for transferring the treated material flow from an upper process chamber to a lower process chamber. In order to separate the two process chambers in terms of gas flow, the transfer device has means for forming a material column in the transition region between the upper and the lower process spaces, wherein said means for forming a material column comprise at least one conveying unit or at least one chute, and the at least one conveying unit or at least one chute also forms a material removal device for the upper process chamber and/or a material input device for the lower process chamber.

A carbon baking furnace has at least one vertical baking shaft with a system and method for positioning green carbon bodies to be baked at the top of the vertical baking path and ringing the green carbon bodies with a sacrificial medium such as packing coke. The disclosure provides a system and method for controlling the delivery and removal of the sacrificial medium used to surround the carbon bodies within the baking paths. A volatile extraction system and method are provided. A system and method for unloading baked carbon bodies is disclosed.

A vertical-type firing apparatus for a positive electrode material for a secondary battery, for vertically moving and firing the positive electrode material for the secondary battery, comprises: a vertical-type firing furnace including an exhaust part, an air supply part, and a firing space positioned between the exhaust part and the air supply part; and a heater for heating the firing space of the vertical-type firing furnace, wherein the firing space includes a temperature-raising space, a cooling space, and a temperature-maintaining space located between the temperature-raising space and the cooling space, and the temperature of the temperature-maintaining space is higher than the temperature of the temperature-raising space and the temperature of the cooling space.
