Eclipse ExtensoHeat Lance Burners, V1, Installation Guide 235, 5/23/2011
■
Adjust the length of each burner seperately in arch
kilns.
• Settle the front plates on their housings.
• Install the burners in the kiln taking precaution to
firmly tighten the locking wing nuts in the neck of the
front plate.
• The securing rings on the side burners (horizontal
position) have to be replaced with sliding flanges
that are to be welded in place with a length suitable
to the wall thickness.
Piping
Layout
Install the piping as shown in the schematics. Refer to
Design Guide 235.
Support the Piping
Use bar supports with height adjustment to support each
group of gas and air piping. Consult your local gas
company with questions.
Pipe Connections
1. Install a pipe union in the gas line to the burner. This
simplifies removal of the burner.
2. The use of flexible pipe nipples in the gas line to the
burner is the most common. Flexible nipples can
absorb stress due to heat expansion and slight
misalignment.
■
Flexible pipe nipples may cause higher pressure
drops than an equivalent standard pipe. Consider
this when you size the air and gas lines.
Avoid Large Pressure Drops
NOTE:
The pressure drop of the gas in the piping is a
critical parameter. Make sure the size of all piping is large
enough to prevent excessive pressure losses.
Valve Installation
Valve Orientation
Install all the valves in such a way that the arrow (if
present) on the valve body points in the direction of flow.
Gas Cocks
Make sure the handle of the gas cock is at a right angle to
the valve body when the valve is in the closed position.
This is an important position indicator. If you do not do this,
somebody may think that the gas cock is in the closed
position, when it is actually in the open position.
Gas Balancing Valves
A gas balancing valve is typically the same as a manual
butterfly valve. For more information, refer to the section
below.
Manual Butterfly Valves
Install manual butterfly valves in accordance with Bulletin/
Info Guide 720.
Automatic Butterfly Valves
An automatic butterfly valve is driven by an actuator
(actuator and mounting bracket not illustrated). Install the
control valve in accordance with Bulletin/Info Guide 720.
Adjustable Limiting Orifices
Adjustable limiting orifice valves are used for fine
adjustment of gas flow. Install the control valve in
accordance with Bulletin/Info Guide 728/730.
Solenoid Valves
Install special solenoid valves for use in pulse control
systems in accordance with the manufacturers
information.
High Pressure Control Valves
Install high pressure gas control valves as specified in the
manufacturer’s installation manual.
Checklist After Installation
To verify proper system installation, do the following:
1. Make sure there are no leaks in the fuel lines or the air
lines.
2. Make sure all the components of the control system
are properly installed. This includes verifying that all
switches are installed in the correct location and that
the wiring, pressure lines and impulse lines are
properly connected.
3. Make sure the blower rotates in the correct direction. If
incorrect, have a qualified electrician rewire the blower
to reverse its rotation.
4. Make sure all valves are installed in their proper
location and correctly oriented relative to the gas or air
flow direction.
5. Make sure all safety components are installed and
working properly.
