Why Do We Vent Kilns?
To Improve your Fired Product
All products
fired in electric kilns contain organic materials that make carbon
monoxide and other fumes when they are burned. These include clays,
glazes, decorating products, decals and the like. Fumes released may
contain sulfur oxides, hydrogen fluoride and metal vapors, depending
on the products fired. Carbon monoxide and other fumes can affect the
color and properties of the fired product if they are not removed from
the kiln earlier in the firing. Red, green, gold and similar products
are particularly affected by carbon monoxide at temperatures where the
color develops.
To Improve your
Work Environment
Removing fumes
released from the kiln from your work environment is important, since
these are unhealthy to breathe on a regular basis. Carbon monoxide can
cause headaches and nausea. Other fumes can potentially cause health
problems.
Methods for
Venting
Typical methods for venting include:
 | Propping lid
and keeping peepholes open until red heat - then closing up kiln
 | Hood above kiln
to capture 70 to 85% of fumes released
 | Venting (such
as downdraft venting) to pull fumes of kiln and pull in fresh air |
| |
Downdraft
Venting
Orton invented downdraft venting some 15 years ago and it is the
standard used to vent electric kilns. With downdraft venting, gases are
pulled out of the kiln near the bottom of the kiln and then mixed with
room air and exhausted to the outside through a duct.
Orton's downdraft venting systems are better than hoods because they
improve firing conditions in the kiln and removes essentially all fumes
from the kiln room. They will improve temperature uniformity in the
kiln, extend the life of heating elements, Kiln Sitter parts and Type K
thermocouples and reduce the cool down of your kiln by 4 to 6 hours.
Also, with the Orton system, the kiln stays closed up during the entire
firing. The Orton venting system is sold under the trade names KilnVent
and Envirovent. Other manufacturers sell systems that pull fumes from
the kiln during firing, but Orton has not measured their effectiveness.
The newer vents (VentMaster)
have the motor mounted away from the kiln. This keeps the motor
cooler, and also if you pull the air out, instead of pushing the air
from the kiln, you won't have fumes in your area even if your hose is
leaking.
