Claim 22:
23. 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;
at least one infrared imaging sensor for the rotary kiln; and
an imaging analysis computer operably coupled with the at least one infrared imaging sensor of each level of the preheater and rotary kiln, wherein the imaging analysis computer is configured to perform the following for each preheater level and rotary kiln:
generate at least one baseline infrared image of a fixed field of view of the preheater level;
generate at least one baseline infrared image of a fixed field of view of the rotary kiln;
obtain at least one subsequent infrared image of the fixed field of view of the preheater level;
obtain at least one subsequent infrared image of the fixed field of view of the rotary kiln;
identify at least one variable temperature region in the at least one infrared image of the preheater level or rotary kiln based on a plurality of pixels in the at least one subsequent infrared image of the preheater level or rotary kiln having a variable difference in temperature from a corresponding plurality of pixels in the at least one baseline infrared image of the preheater level or rotary kiln, wherein the at least one variable temperature region includes the plurality of pixels having a baseline temperature and having a subsequent temperature that is the variable distance in temperature;
generate a visual representation of the at least one variable temperature region of the preheater level or rotary kiln; and
display the visual representation that identifies the presence of the at least one variable temperature region in the fixed field of view of the preheater level or rotary kiln.
