1. An injection device for supplying a gas to a material to be calcined, the injection device comprising:
a) a heat exchanger housing;
b) at least one inlet into the injection device and through which the gas can be fed to the injection device and at least one outlet from the injection device through which the gas can be supplied from the injection device, wherein the at least one inlet and the at least one outlet are connected to one another by a flow path for the gas;
wherein
c) the flow path extends through a heat exchanger within the heat exchanger housing, which is accessible to an ambient atmosphere from the outside and in which a channel arrangement is accommodated;
d) the channel arrangement comprises at least a first flow channel and a second flow channel between which a diversion region is formed in such a way that the gas can flow with different main flow directions through the first and second flow channels; and
e) the first and second flow channels and the diversion region in the heat exchanger housing are formed by a flow guide element so that the channel arrangement with the first flow channel, the diversion region, and the second flow channel is formed by a housing outer wall of the heat exchanger housing and the flow guide element.
