FRIT SYSTEM A and B
Reversal Control
- Has two positions, turns gas ignition off on one side of the furnace and ignites it on the other.
- The reversal system automatically alternates the sides which are firing, the fumes also automatically will be diverted to the opposing side.
- This system allows balanced furnace temperature.
- CC Displays both Gas flow and Valve positions.
MELTER & CONDITIONING SYSTEM
- Works in conjunction with FRIT system
CC Displays gas operator position, combustion air, stack inverter speed (90-71-63).
Melter High Temp Limit, Low Limit Combustion Air Flow Limit (1479,1479,43.8), Maximum Trip @ (1580 or 788 deg C).
- FUEL EMERGENCY SHUTOFF LOCATION.
CHARGER SYSTEM FURNACE East, West, A and B
- Many PLC or Manual VFD controlled motors which shovel material into the furnace.
- 2x for the Charger motors (1.5-1.7A). 2x for the Hydra mix (7.6-7.8A). 2x for the pumps. (Unk)
- You could run in manual at the following amounts from left to right.
- 5x Positions.
- More evenly distributes material into furnace.
- Has local Jog buttons. In manual mode.
- Arms of Oscillator move back and forth within the furnace distributing material inverted to one another. ( /.\ | \ . / )

Charger Cabinet
- The frit System monitors and controls the aspects of the ignition system.
- a. Air: Fresh air is accumulated in one side of the furnace. It is brought in through a Stack with help to maintain pressure with two fans which are driven by two inverter drives.
- The air is brought in to supply the combustion process. That air then takes the path of least resistance to the exhaust side.
- Upon reversal there is a flap which switches which side of the furnace is allowed to exhaust. The side which exhausts is opposite the side which gas ignites on.
- There are five gas burners which correspond to five air inlets.
- The front burners closest to material entry burn at the highest BTU.

EXHAUST TO REVERSAL ROOM
Reversal GEAR??????
- The Reversal System involves the ability at the exhaust to switch the side of the furnace which air exhausts through the stack.
Boost System
Boost Electrode
- The Boost is used for auxiliary heating of the furnace.
- The Boost electrodes protrude into the furnace floor from underneath.

Boost Tap Procedure
- Batch house operator will instruct you on the transformer they would like to use for boosting. ie.. CD BE or something, and they will also tell you what tap number they would like. This will allow them to increase and decrease the amount current / temperature given to the boost electrodes.
- Shut off boost control by removing key from operator panel.
- Next, bring that key to the large disconnect with a key interlock. Use key, throw switch and grab other key.
- Next, take that new key and
turn it on the green control board behind you. Now take the key which corresponds to the transformer being adjusted.
- Next, take that new key and
- Now use that key to go to the transformer up the stairs and again get a new key at an interlock. Go around to the back and adjust a wheel to the correct tap number selected by the operator.
- Now do that same process in reverse.
