Claim 0:
1. An apparatus for thermal or thermochemical treatment of material, comprising
a) a housing;
b) a process chamber within the housing;
c) a conveying system, by means of which the material or support structures laden with the material can be conveyed in a conveying direction into or through the process chamber;
d) a heating system, by means of which a process chamber atmosphere present in the process chamber can be heated up;
e) a process gas system, by means of which the process chamber can be supplied with a process gas required for the thermal treatment of the material,
wherein
f) the process gas system comprises multiple local injection devices arranged and set up such that process gas in multiple local process gas streams each with a main flow direction can be delivered targeted onto the material or onto the support structures laden with material, and
wherein
g) at least one local injection device includes multiple injection nozzles set up in such a way that multiple process gas streams can be delivered at different angles relative to each other and relative to the conveying direction and a horizontal reference plane.
