A kiln damper is the device that regulates the size of the opening of the flue.
Understanding the Kiln Damper
In the construction of a kiln, such as a beehive design, enclosing the firing chamber is essential. However, this enclosure naturally restricts the flow of oxygen needed for combustion. Without adequate ventilation, the kiln cannot burn properly. To overcome this, a crucial component is included: a hole at the top known as a flue.
Based on the provided reference:
- The enclosed kiln design restricts oxygen.
- Lack of ventilation prevents proper burning.
- A flue (a hole at the top) provides necessary ventilation.
- The DAMPER is the device specifically used to control the opening size of this flue.
Role and Importance
The primary role of the damper is to manage the airflow through the kiln's flue. By adjusting the size of the flue opening, the damper allows the operator to control:
- Airflow: Regulating the amount of oxygen entering or gases exiting the kiln.
- Temperature: Affecting the rate of burning and heat distribution.
- Atmosphere: Influencing whether the kiln is firing in an oxidizing or reducing environment.
Key Components in Kiln Ventilation
A simple kiln ventilation system often involves these main parts:
- Kiln Body: The enclosed structure where firing takes place.
- Flue: The opening (often at the top) that allows gases to escape and air to enter.
- Damper: The adjustable device positioned at or near the flue opening to control its size.
Controlling the flue opening with a damper is a fundamental technique used by potters and ceramic artists to achieve specific firing results.
