The modern Hoffman kiln takes the form of two parallel tunnels built side by side, connected 

by curved tunnels at either end, the basic principal of the moving firing zone, coupled with 

continuous loading and unloading. The arch of the tunnel being is supported on the side walls. In order to increase output, continuous kilns with longer circuits through which the firing zone 

travels more rapidly are built. Two firing zones run simultaneously are possible on the larger 

kilns, with a high rate of firing travel, assisted by a strong fan system and sending waste heat for brick drying. Some kilns can be 500 feet long.

**The structure and working principle of Hoffman kiln**

A Hoffmann kiln consists of a main fire passage surrounded on each side by several small rooms. Each room contains a pallet of bricks. In the main fire passage there is a fire wagon, that holds a fire that burns continuously. Each room is fired for a specific time, until the bricks are vitrified properly, and thereafter the fire wagon is rolled to the next room to be fired.
