The invention relates to a device for the thermal or thermo-chemical treatment, more particularly calcination, of material (12), more particularly battery cathode material (14), comprising a housing (16), in which a process space (20) is located. The material (12), or carrying structures (40) loaded with the material (12), can be conveyed in a conveying direction (30) into or through the process space (20) by means of a conveying system (28). A process space atmosphere (50) prevailing in the process space (20) can be heated by means of a heating system (48). There is a process gas system (64), by means of which a process gas (66) can be fed to the process space (20), said process gas being required for the thermal treatment of the material (12). The process gas system (64) comprises a plurality of local injection units (68), which are arranged and configured such that process gas (66) can be released in a targeted manner onto the material (12) or onto the carrying structures (40) loaded with material (12), the process gas being released in a plurality of local process gas streams (70), each having a main stream direction (72). The invention also specifies a method for the thermal or thermo-chemical treatment of material (12), in which process gas (66) is released in a targeted manner onto the material (12) or onto the carrying structures (40) loaded with material (12), the process gas being released in a plurality of local process gas streams (70), each having a main stream direction (72).

A method is provided for heating a furnace arranged with a heating zone heated with a burner providing a flame extending in a longitudinal direction and fed with a fuel and a primary oxidant, the burner is operated with a mass relationship between the fed fuel and primary oxidant permitting less than 50% of the fed fuel to be combusted using the primary oxidant, and a respective pair of secondary oxidant lances are provided one either side of the furnace pointing into the heating zone, lancing a secondary oxidant into the heating zone downstream of the burner substantially parallel with a cross plane, such that a temperature is measured downstream of the lances and that each of the lance pairs includes an upstream, low-speed first and a downstream, high-speed second lance, wherein the amount of secondary oxidant supplied via the first lance is regulated to achieve a homogenous lateral temperature profile. A related furnace is also provided.

A kiln car assembly for a firing kiln having a plurality of upper burners includes a kiln car with an uppermost plurality of ceramic green bodies, a plurality of vertical members, and a horizontal supporting plate for supporting the ceramic green bodies during a firing process in the kiln. Further, the kiln car assembly includes a covering table having a tabletop located between the uppermost plurality of ceramic green bodies and the upper burners, and a plurality of legs positioned on the horizontal supporting plate.

A foaming heating system includes a furnace, a conveying device, a heating device and a plurality of detectors. The furnace has a furnace body, a heating channel and ventilation holes. The conveying device transports foam material passing through the heating channel. The heating device has a heater, a heating tube, a temperature regulator and at least one temperature adjustment pipeline. The plurality of detectors detects the temperature of each section of the heating channel. When a temperature abnormality of a certain section is detected, the temperature of the certain section is adjusted by the at least one temperature adjustment pipeline.
