Lime production was sometimes carried out on an industrial scale. One example at Annery in North Devon, England, near Great Torrington, was made up of three kilns grouped together in an L shape and was situated beside the Torrington canal and the River Torridge to bring in the limestone and coal, and to transport away the calcined lime in the days before properly metalled roads existed.
Sets of seven kilns were common. A loading gang and an unloading gang would work the kilns in rotation through the week.
A rarely used kiln was known as a "lazy kiln".
