Construction of Wood-Fired Kiln


Foundation
The foundation consists of a concrete pad, for stability; a course of cinder block for elevation and heat buffer; and two courses of firebrick for further elevation and protection of the foundation.

The Kiln Floor
The floor is made up of four 1 x 18 x 24" silicon carbide shelves, which are covered by a 2" course of Insulating
Fire Brick.



Constructing the Walls
The walls are coming to a height of 33" and ready for the arched roof.



Alternate Fireboxes
The fireboxes are made up of a unique Detrick firebrick, designed for a hanging system. Cavities were filled with crushed IFB material.


Kiln Floor–continued
The idea is two-fold, first  to help protect the shelves from the dramatic temperature variation of the inner chamber and the fireboxes; and secondly, to help distribute weight evenly on these used and slightly damaged shelves.

Side View: firebox and reinforcement steel.
The foundation of the kiln is elevated using cinder block on edge. This effectively eases stoking.
Alternate Fireboxes
Height of the fireboxes is at five courses to allow for a grate height of nine inches and plenty of room for a coal bed and adequate airflow.


The Interior, Showing one inlet and the Exit Flue
The flue is temporarily supported by two bricks while under construction.


Arch is in place
At this point preparations are being made for the steel framed reinforcement.
