Olympic TorchBearer Gas Kilns
Olympic has incorporated the high quality standards of its electric
kilns into the Torchbearer Gas Kilns. Portable gas kilns offer
many advantages such as low initial cost, convenient movement for
demonstration firings, and for use in situations where space does not
permit the installation of large permanent kilns.
 |
The Olympic torchbearers will fire to cone 10 using natural gas,
propane, or butane, and may be easily adjusted for oxidation, reduction,
or Raku firing. The multiple burner configuration gives the
Torchbearers very even heating characteristics, fast controllable firing
times, and economical operation.
For setup, contact your local gas company to purchase 3/4"
pipeline, low pressure regulator and gas tank (if running on
propane.) Propane runs on 11" water column (water column is
rate of gas pressure.) Natural gas runs on 7" water
column. Gas consumption per firing: 18" model, 5 gallons per
firing. 23" model, 7-10 gallons per firing. 28"
model, 10 gallons per firing.
Olympic approximates that to achieve a cone 10
firing, you will use one gallon of LPG, per every cubic foot of kiln
volume, (i.e. The 7 cu ft 2327G, will consume approximately 7 cu ft of
LPG for cone 10.)
Note about these kilns:
These gas kilns look like
electric kilns, complete with sections, but they are not as easy to fire. Typically
it takes much
more testing and experimentation to get good results from a gas kiln.
Gas kilns are simply a more complex of a firing system. For example, you may
have to raise the bottom shelf, or put an extra shelf at the top of the
kiln to get it to fire evenly. Will also have to learn how to adjust the
burners for an oxidation or reduction environment. If you are
willing to take on these types of issues,
then these kilns can be a great alternative to a larger downdraft models,
especially if you are on a tight budget. But please be
warned, gas kilns are not for beginners or for someone who just wants to
press a button and have the kiln fire itself.

Torchbearer Options
(for any of the torchbearer kilns): |
| Please specify
Propane or Natural Gas. This determines the burner type. (The
kiln burners can be inexpensively changed later on if you gas source
should change.) |

Gas Kiln Sitter System -
The kiln sitter provides an automatic shut-off when the kiln reaches a
specified cone temperature. The limit timer will shut the kiln off at a
preset time. An electric valve runs the gas kiln sitter. Requires a
120 volt outlet. |

Comes with 3 key controller. (12 key pictured.) |
120 Volt Electronic Controller - Olympic's electronic wall unit features programming by cone number or allows you to create your own programs. Each program has eight segments with ramp/hold profiles and controlled cooling rate. The controller features convenient program review before or during a firing. Because the electronic controller runs in an on/off mode and is not proportional, the gas kiln operator will need to manually adjust the gas flow several times as the kiln reaches 1500F, when the controller can fully automate the firing. Includes valves necessary for controlling gas flow. (Requires purchase of ignition ring). |

|
|
|
Pyrometer -
An analog pyrometer is an available option for measuring temperature of
the kiln while firing. Pyrometers should be wall mounted away from the
kiln to prevent damage to the instrument. Olympic's pyrometer is rated
0-2500F. 6" thermocouple |
