Operating Cycle
Firing Zone (in roof)
For each group:
• Manually start the combustion air blower
• Check that the air actuator is closed
• Open the manual air and gas valves for each burner
• Press the main group start button. Air is set to
maximum and the burner main group safety
solenoid valve opens
• Temperature regulation takes place according to
selected type and mode
NOTE:
During burner operation, the air flow is always
constant. The regulation cycles only take place with “car
stopped”. During each “car advance” the main group
safety valve closes, and the air actuator closes.
Stop
• Press the group(s) stop button
• Close the main and burner manual gas valve (firing
zone in kiln’s roof)
• If the kiln is maintained in operation, remove the
burners and close the holes
• In case of kiln stop, do not switch off the combustion
blower until the kiln temperature is less than 572ºF
(300ºC) and then close the air valves for each
burner
• Switch off the electrical power
NOTE:
Keep the blower running after the burner is turned
off to protect the burner and other components from any
back flow of hot gases.
■
The following must be immediately carried out in
case of main power failure:
■
Close all manual air valves so that the burners are
isolated from the distribution manifolds and
prevent the return of hot gases through the
burners.
■
In case of a long power failure (more than 15
minutes), the burners should be removed from
their positions to prevent them from being
exposed to high temperatures for a prolonged
period.
■
Select resistant material for air pipes if there is a
possibility of temporary reversal of hot gases.
