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.
The Hoffmann kiln is a so-called "continuous kiln" - it burns 24 hours a day, 7 days a week, 365 days a year (except when it goes down for maintenance). Before its invention, bricks and tiles were fired in so-called "periodic kilns"
