Claim 14:
15. A system for measuring temperatures of a preheater of a rotary kiln, comprising:
at least one infrared imaging sensor for each level of the preheater, wherein the preheater includes at least two preheater levels; and
an imaging analysis computer operably coupled with the at least one infrared imaging sensor of each level of the preheater, wherein the imaging analysis computer is configured to perform the following for each preheater level:
generate at least one baseline infrared image of a fixed field of view of the preheater level;
obtain at least one subsequent infrared image of the fixed field of view of the preheater level;
identify at least one variable temperature region in the at least one infrared image based on a plurality of pixels in the at least one subsequent infrared image having a variable difference in temperature from a corresponding plurality of pixels in the at least one baseline infrared image, wherein the at least one variable temperature region includes the plurality of pixels having a baseline temperature from the at least one baseline infrared image and having a subsequent temperature that is the variable distance in temperature;
generate a visual representation of the at least one variable temperature region; and
display the visual representation that identifies the presence of the at least one variable temperature region in the fixed field of view.
