A kiln should be aligned when it is in operation for four very important reasons: 1. A straight cold kiln has a measurable misalignment at operating temperatures. This is because the shell axis elevation increases by one half of the thermal expansion of the shell diameter. This expansion is the function of the shell temperature and, as such, it
