Shaft kilns. The theoretical heat (the standard enthalpy) of reaction required to make high-calcium lime is around 3.15 MJ per kg of lime, so the batch kilns were only around 20% efficient.The key to development in efficiency was the invention of continuous kilns, avoiding the wasteful heat-up and cool-down cycles of the batch kilns.

When subjected to torsion, every cross-section of a circular shaft remains plane and undistorted then the bar is said to be under pure torsion. Cross-sections for hollow and solid circular shafts remain plain and undistorted because a circular shaft is axisymmetric. Cross-sections of noncircular (non-axisymmetric) shafts are distorted when ...
