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.
