8 MULTI-BURNER OPERATION
8.1 Multi-Burner Overview
Some special applications such as dual furnace fire tube boilers, multi-burner water tube boilers and other
application may require Multi-Burner operation. This feature can be used where two or more independent
burners require controlling simultaneously.
In multi-burner operation setup, all components must be kept separate and independent for each burner, so
each burner should have its own independent components, this includes:
• Air damper.
• Air fan / blower and its motor.
• Induced draught fan / blower and its motor.
• Draught control damper / valve and its control servomotor.
• Draught pressure sensor.
• Air pressure sensor or switch.
• Gas pressure sensor or switch.
• Forced FGR fan / blower.
• FGR valve and its control servomotor.
In multi-burner operation a leading MM is set as the main controller; this is called the Master MM, any other
MM units in the setup are secondary and called Salve MMs. In a multi-burner setup only one Master MM can
be setup and as many as 9 Slave MMs can be used to control up to 10 burners in total.
Note:
• All MMs in a multi-burner operation must have identical version of the software (MM, BC & DI).
• Fuel Change on the Fly (COF) feature cannot be used with Multi-Burner operation.
