Hoffman kiln

1. Introduction and History

Hoffman kiln is a continuous, moving fire kiln in which the fire is always burning and moving forward through the bricks stacked in the circular, elliptical or rectangular shaped closed circuit with arched roof. The fire movement is caused by the draught provided by a chimney or a fan. Hoffman kiln was developed and patented by Friedrich Hoffman in Germany in the year 1858. There kilns were once wildly used in Europe for bricks, ceramics and lime production.

The original design of Hoffman kiln has a circular circuit around a central chimney. However, this design has been modified with time and now Hoffman kiln with elliptical or rectangular shape are more in practice.
