STANDARD FEATURES
ON ALL GAS KILNS

  • Electronic flame safety, 100% Shut Off.
  • Push button automatic spark ignition.
  • Manual control valve.
  • 0-15" water column pressure gauge.
  • DD-1 digital, solid state, electronic controller which functions as a high-limit, on/off soaking controller.
DD-1 Digital Electronic Controller
The DD-1 is a high limit, on-off solid state electronic controller with a digital read­out and digital set from 0 to 2500º F. When the controller is set at the “High Limit” position, it will automatically shut the kiln off at the set point temperature. The on-off position functions as a “soaking” controller, holding the temperature at the set point temperature plus or minus 5º

Burner System
Natural draft, high velocity ceramic Venturi burners were specifically created and designed by GEIL Kiln Company for the GEIL Downdraft Design system and have proven to be quite efficient in all applications.

Heavy Duty Hinge
An exclusive feature on all front loading GEIL Kilns, this hinge is fully greased to prevent rusting and reduce wear.

OPTIONAL EQUIPMENT

  • Automatic damper system
  • Microprocessor Based Programmable
    temperature Controller.

GEIL KILNS ARE AVAILABLE IN SEVERAL CONFIGURATIONS:

BRICK, FIBER, MEDIUM DUTY, and SHUTTLE



GEIL Brick Lined Natural Draft Kilns

The frame construction and exterior shell of the GEIL Downdraft Gas Fired Fire Brick Kilns consists of heavy gauge structural strength steel. All frames are welded at each joint to provide for maximum strength and durability. Full width, front loading doors and the minimal area between the door opening and the setting space facilitates loading and unloading. These fire brick kilns are built with full depth arch construction extending directly to the door opening, providing stacking space to the top of the arch, 2600º F and 2800º F High Alumina (60% or more) Insulating Fire Brick backed by high-temperature block insulation constitutes the kiln's interior. All DL models will fire to 2500º F (cone 14).
Natural draft, high velocity ceramic burners were specifically designed and developed by GEIL Kilns to produce excellent fuel-air mixture without the need of electric blowers. These burners provide for simple and trouble-free firing.
GEIL Forced Draft Kilns
Forced Draft models are the same superior construction technique as that of the Natural Draft models, with the exception of the burner system.

A standard Forced Draft system incorporates the use of an electric blower to force air through the burners to insure complete combustion. The Geil Forced Draft System is particularly unique in that the forced draft burners are placed in the same position as our Natural Draft models, thus maintaining the same downdraft circulation and functioning much like our Natural Draft models. All specifications for the Forced Draft Kilns are the same as the Natural Draft except the number of burners

Fiber Lined Front Loading Kilns

The use of ceramic fiber as a kiln insulator offers the kiln user several important advantages over kilns constructed with a conventional refractory insulation, including:
Lightweight: Ceramic fiber linings are 75% lighter than insulating fire brick linings and 90-95% lighter than dense refractory linings.
Low Heat Storage: Low heat storage is the most important advantage of a ceramic fiber lining. Heat storage is directly proportionate to the weight of the material used in the kiln lining. The lighter the lining, the fewer BTUs needed to bring the kiln up to temperature. The BTUs required to fire is directly related to energy consumed. Thus, the fewer the BTUs consumed, the more energy conserved.
Moreover, the kiln can achieve its maximum temperature more quickly and can cool down faster over kilns constructed with insulating fire brick. Shorter operating cycles increase productivity and save wear and tear on the kiln.
Thermal Shock Resistance: Fiber linings are completely immune to damage from thermal shock. Therefore, predetermined heat up/ cool down cycles dictated by the kiln's lining are eliminated. Once the firing cycle is completed, access to the kiln can be immediate without fear of damaging the lining.
Thermal Efficiency: Fiber linings are thermally more efficient then conventional refractory linings. The low thermal conductivity of fiber means the lining thickness can be reduced, thereby decreasing outside dimensions. Additionally, fiber heats at a more uniform rate, allowing for a more uniform temperature distribution within the kiln chamber.

Resiliency: In that fiber is extremely resilient and withstands movement well, kilns are transported easily without fear of damage. Kilns are test fired in our factory prior to shipping which eliminates any possible problems before they start.
Ease of Repair: Should physical damage to the lining occur, the damaged section is simply cut out with a knife and new material inserted. Repairs are made quickly with a minimal amount of expense and downtime.
Energy Savings: Research has shown that ceramic fiber kilns conserve as much as 30-40% in energy over comparably sized insulating fire brick kilns. Such tremendous savings means much faster payback periods.

Cool Down: All GEIL fiber kilns have been designed and engineered to insure a cool down rate equal to that of similar sized brick kilns. Cool down can be easily controlled by damper adjustments. A normal cool down requires the damper to remain closed. This may be hastened by opening the damper slightly.

Insulating Fire Brick Lined
Shuttle Kilns
GEIL Natural Draft Kilns
All GEIL Shuttle Kilns are constructed with the same solid steel construction as our front loading models. Heavy duty V-grooved steel casters are used on the car portion of the kiln, enabling the car to roll freely on angle iron tracks. 2600º F and 2800º F High Alumina (60% or more) Insulating Fire Brick backed by high temperature block insulation constitutes this kiln's interior. All models will fire to 2500
º F (cone 14).
The two car Shuttle Kiln has long been known for its high production capabilities. While one car load is being fired, the other car may be simultaneously loaded or unloaded, preparing for the next firing cycle. This conserves time and increases production considerably.
The major advantage of a car type construction is the ease of loading and unloading. A Shuttle Kiln curtails strenuous and often cumbersome loading and unloading, characteristic of larger, front loading units. Additionally, Shuttle Kilns offer the added advantage of loading and unloading from both sides.

Two car Shuttle Kilns are also available. Specifications differ in the length overall, call GEIL Kilns for details. Shuttle Kilns are available in the Natural Draft or Forced Draft design. Envelope Kilns are also available, call GEIL Kilns for details.

Medium Duty Kiln Model 802

GEIL offers the ceramicist a front loading Medium Duty Kiln capable of cone 10 oxidation/reduction firing. This model incorporates the same original Downdraft Design with fiber lining. The primary difference between the Medium Duty Kilns and our professional kilns is a lighter-duty form of construction. This model is equipped with steel casters for complete portability.

OPTIONAL EQUIPMENT
Automatic Damper
System

The microprocessor controller is the main controller of the system, responsible for time, temperature and atmosphere of a kiln firing. It reads the temperature by means of a thermocouple mounted on the back wall protruding into the interior of the kiln. The microprocessor then processes the pre-programmed parameters (i.e.: ramp soak segments) and adjusts the output signal to the proportioning valve located on the valve train. Depending on the call for heat from the microprocessor, the proportioning valve will vary the amount of gas reaching the burners. The kiln is also equipped with an oxygen probe located just below the thermocouple. Reading the atmosphere of the kiln via the oxygen probe, the microprocessor sends a signal to the damper motor which then adjusts the damper automatically to control the atmosphere.

By programming the microprocessor’s parameters with time and temperature, the kiln can be fired by ramping to a set point within a particular time frame. This ramp time plus a soak time is one segment. The microprocessor contains four ramp soak segments making up what is called a firing profile. This profile is stored in the microprocessor’s nonvolatile memory. The microprocessor contains two operating modes, AUTO and MANUAL. These pre-programmed firing profiles can be operated by the AUTO mode. The kiln can also be fired manually by the microprocessor controller.

Our auto-damper system is PC controlled using a windows based program that is very easy to operate and hook up. All the parameters from the controller are displayed on your computer screen, making it easier to update and change your firing profiles. The program takes about 5 megabytes of space on your hard disk. There are no major upgrades needed for you to install and connect the microprocessor program. The microprocessor program offers remote station firing capabilities.

The microprocessor controller is equipped with a high limit alarm. The high limit alarm will shut the kiln down once the kiln hits the high limit temperature. The damper is automatically closed to prevent any thermal shock. lf there is any disruption of gas or flame failure, the flame safety system will automatically shut the kiln down. Our auto-damper system is backed by a CSA (Canadian Standard Association) certification meeting the required safety standards for gas appliances.

OPTIONAL EQUIPMENT
Microprocessor Controller
UNDERSTANDING THE PYX MICROPROCESSOR

The PYX controller is the main controller of the system, responsible for the time and temperature of a kiln firing. It reads the temperature by means of a thermocouple mounted on the back wall protruding into the interior of the kiln. The PYX reads the temperature via the thermocouple. It then processes the pre-programmed information (ie: ramp soak segments) and adjusts the output signal to the proportioning valve. Depending on the call for heat form the PYX, the proportioning valve will vary the amount of gas reaching the burners. The output signal is shown as a percent in the OUT1 parameter. Each parameter is explained in detail in the next section.

By programming the PYX parameters with time and temperature, the kiln can be fired by ramping to a set point in a particular time. This ramp time plus a soak time is one segment. The PYX contains four ramp soak segments making up what is called a firing profile. This profile is stored in the microprocessor’s nonvolatile memory. The PYX contains two operating modes, AUTO and MANUAL. This pre-programmed profile is operated by the AUTO mode. The kiln can also be fired manually by the PYX controller. Manual firing can be used to perform a reduction.
