B . SAFETY INSTRUCTIONS
The use of oxygen in oxy-combustion imposes safety procedures:
●Never use oil or grease for oxygen piping, or for burner assembly parts
●No carbon steel for high temperature and/or high speed
●Do not use organic materials for sealing purposes
●Always clean all metallic parts before installing them (eliminate all traces of oil and grease)
●Operators training for oxygen use
Failure to follow these instructions may cause ignition in the oxygen circuit and further propagation along
the oxygen piping.

D . DESCRIPTION OF THE ALGLASS BURNER
Built to operate on various types of glass making furnaces, the material used is especially suited for this
purpose.
In general, the metals used offer a good resistance to corrosion for the burner's "cold part", and good
resistance to temperature and oxidation for the "hot part".
Generally speaking, all of the metal alloys employed are perfectly compatible with pure oxygen using.
Each burner metal component part bears its production file number.
The burner block is refractory material. This refractory material is chosen to be compatible with the
particular glass making process and the type of superstructures.
The gaseous fuel version of the ALGLASS burner comprises six component parts, and the liquid fuel
version comprises five parts.
The gas/fuel oil burner consists of the following parts. (Fig.1)
●The burner block made of refractory material.
●The fixation system for mounting the burner body on the block, consisting of two half sections.
●A ceramic packing to be positioned between the burner block and the burner body.
●The burner body with its VITON O-ring, mounted in the flange groove and a closing flange to be
mounted back on the body.
●A gas lance with 1, 3 or 5 tubes.
●A dual lance with injector and nozzle

F . BURNER CHOICE
1 ) FLAME LENGTH
Gas version: basically, this burner can adjust flame length changing the gas lance between 1, 3, 5 tubes
geometry. More tubes make a shorter flame.
Dual version: basically, this burner can adjust flame length using adjusting atomizing air pressure
Attention : flame shape could be changed with oil viscosity. Please adjust suited viscosity.
2 ) COOLING AIR
During combustion, the burner body, gas lance and burner block are cooled by the fluid used for
combustion.
However, when combustion is off, all parts of burner are heated.
In this case, put into cooling air using oxygen line.
Atomizing air is not only atomizing but also to cool down oil lance.
Never stop the atomizing air while oil lance is located in burner block and hot furnace.
3 ) BURNER BLOCK
The usual size of the burner block is 220 x 220 mm .The size of the furnace opening should be more than
this dimension.

G . INSTALLATION AND ASSEMBLY
The main difference between the Gas and Dual ALGLASS burner version resides in the fuel lance.
Their assembly and installation procedures are therefore practically the same.
The burner block and adapters must be pre-assembled before installing on the furnace.
On a recently built furnace, burner block will be installed on the furnace before starting heating up.
1 ) INSTALLING THE BURNER ADAPTER
Before installing the burner block, check that the support of the block is horizontal or inclined a few angle
towards the glass level, to be sure that flame are not oriented towards the crown of the furnace.
●Install the two half-sections adapter on the block with the attached bolts and tighten moderately

●Place the burner block with its adapter in their opening and push them into their final position,
tighten the devices for securing the block in place.
●Plug the hole in the block with an alumina wool plug.
2 ) ASSEMBLY OF A BURNER BODY
First of all, for safety reason it is essential that all traces of grease must be removed from the metal burner
parts, before O-ring are installed, to avoid accidental combustion.
Before this burner is run, the burner body will be mounted on the block.
Then, for operating with fuel, the assembly procedure is as follows :
●Please make sure that Viton O-ring is set to the burner body.
●Check the oxygen connection.
●Check the oxygen supply.
●Mount the 3 mm thick, 140 x 140 mm square ceramic packing on the burner body nozzle.
●Mounting the blind flange by using the attached 3 bolts.
●Remove the alumina wool plug from the block and place the burner body nozzle in the hole of the
block.

ASSEMBLING THE FUEL OIL LANCE:
Dual lance composition
●Set the couplers and flex hoses to the oil port (¼”) and atomization air port (⅜”).
●As for the attached coupler, female part has check valve. So please set female parts to lance and
male parts to flex hose.
●Insert the O-ring on the fuel oil injector (only available for ALGLASS DUAL 1000).
●Screw the fuel oil injector on the DUAL lance tip and squeeze it to assure the tightness.
●Mount the nozzle on the fuel oil lance tip and squeeze to fix it without any tools.
●Check that the calibrated orifice is in place in the external air circuit.

MOUNTING THE DUAL LANCE IN THE BODY:
The fuel oil lance will be assembled to the burner body when ready for igniting the burner.
First, check that the fuel oil lance is correctly assembled.
The assembly procedure is as follows:
●Connect oil and atomizing air flex tubes to each inlet.
●First, put into atomizing air .
●Don't switch off the cooling air supply until combustion is started.
●Dismount the blind flange while taking precautions to protect yourself from the hot gas that may be
expelled due to positive furnace pressure.
●Place the fuel oil lance in the burner body. The lance attached angle is changeable.

H . IGNITION AND EXTINCTION PROCEDURE
1 ) IGNITION
According to the previous section, at this moment, the burner is ready to ignite. There is air cooling flow on
the burner and atomizing air if Dual lance is used.
●Check oxygen and gas valves position on piping.
●Flow oxygen in burner at minimum value (30% of nominal) and stoichiometric gas (using manual mode
or automatic sequence of PID)
●Check the ignition of the flame
●When oxygen flow exceeds 30% of the rating, close the air cooling valve
●Adjust atomizing fluid pressure depending on the flame length if Dual lance is used
2 ) EXTINCTION
To stop a burner , decrease the power around 30% of the rating,
When stopping burners, observe the following sequence and fluid flow conditions:
●Decrease the power around 30% of the rating,
●Close the gas valve nearest to the burner
●Check that the burner is off
●Open air cooling valve and check flow
●Close oxygen valve
●if Dual lance is used:
○Decrease atomizing fluid pressure until 1 bar to purge oil in the lance
○Just before removing the oil lance, close atomizing air valve
●Remove the gas/Dual lance and plug using blind flange
