The Hoffman Kiln

This massive kiln was built in 1873 for the Craven Lime Company. It had 22 individual burning chambers. Limestone was burned continuously in a circuit around the kiln. It took an average of 6 weeks for one whole circuit.

The limestone blocks from the quarry were barrowed in and carefully stacked by hand in the burning chamber. Coal was mixed in, and once lit, more added through small coal chutes from the top of the kiln.
The complicated flue system allowed the heat and speed of the burn around the kiln to be carefully regulated. As one chamber burned, waste heat warmed limestone blocks in the next two or three chambers. Behind the burning zone, two or three chambers were left to cool down before the lime could be shovelled out and loaded onto railway wagons waiting in the sidings beside the kiln.

The kiln is of an oval shape and there is another vast chamber to the left of this one of equal proportions.
