Kiln

Overview

A kiln is a giant oven that enables the hardening, burning, drying, or firing of materials.

Easily constructed with CEB or Concrete, a Kiln serves a wide number of useful functions

Product Ecology

Kiln

Made of

• CEB - walls, floor
• Concrete Mixer - Concrete
• Controller Box - Temperature controls

Uses

• Sawmill - Lumber
• Gasifier - Heat
• CEBs - Bricks
• Pelletizer - Dries pellets

Creates

• Lumber (dried)
• Charcoal (via wood pyrolysis
• Cement (clay + lime) for Concrete Mixer.
• Glass
• Metal (smelted from ore)
• Bricks (fired)
• Pellets

Applications

Wood Drying

A freshly felled tree cut into logs and run through the Sawmill will produce Green Wood. While viable as a construction material in many applications, green lumber has a nasty habit of warping and shrinking over time (which can cause issues).

One approach toward addressing this is simple air drying. The lumber is stacked in a clean, cool, dry and shady area, atop raised foundations, with spacers (called stickers) laid crossways at regular intervals for ventilation. While air-drying Sawmill lumber is a viable option (and produces high-quality lumber), it is a process that can take months to years.

A kiln accelerates this process by rapidly heating and drying the lumber, enabling on demand fabrication of wood products.

Bricks

Additional structural strength can be gained from CEBs upon firing in a kiln (although this is unnecessary in many applications]].
