General Notes:
1. Mounting illustrations show typical Vortometric combustor blocks of high alumina
plastic refractory as used by Eclipse for normal duty.
2. The dimensions given must be held as specified, and the inner diameter of the
combustor must be round and concentric with the throat cone.
3. Alloy rod-type anchors welded inside the combustor block are the customer's
responsibility if the refractory is field installed rather than factory installed.
4. All mounting arrangements are meant for vertically or horizontally fired burners.
Regardless of orientation, the refractory block MUST be protected from thermal
expansion of the furnace wall.

*178mm (7") for 6V and 8V medium intensity burner sizes.
Furnace shell plate
Weld heads of mounting bolts inside furnace shell plate.
Allow for 3mm (1/8") thick, high temperature gasket
between the burner flange and shell plate.
To allow for thermal expansion of combustion liner extension,
the main wall should be constructed with an opening 25mm (1") greater
Ring
in diameter than diameter of combustion liner.
The outside of combustion liner should be covered with 1/8" thick
insulating paper. The remaining gap between the burner and main wall
Smooth refractory
should be densely packed with ceramic fiber or wool blanket insulation.
