Rings of fire: Hoffmann kilns
These are called Bull's trench kilns – named after its British inventor W. Bull – and they are common in Pakistan, India, Bangladesh, Nepal (some great pictures here) and Myanmar. These semi-continuous kilns – 100 to 150 metres long and usually built in a trench – produce bricks of similar strength, but with a lesser esthetic quality.
Hoffmann's Kiln and Bull's trench kiln
The Bull's trench kiln. The kiln can be made circular or elliptical in shape. It is constructed on dry land, by digging trench, 6 – 9 m wide, 2 – 2.5 m deep, and 100 – 150 m long. An alternative method is to build up the sides of the kiln with bricks, especially where drainage is a problem. Gaps are left in the outer wall for easy ...
