INTRODUCTION
1.1 OVERVIEW
The Combustex BMS-2000 Burner Management System has been designed to be compatible with a wide
variety of industrial and oileld burner vessels. A common vessel will have a main burner ring into a re
tube which, in turn, heats a uid (often glycol). This uid is referred to as the “Bath”. Another uid (oil or
gas) is routed through the bath to be heated. This is referred to as the“Process”.
The BMS will control up to two pilots and two main burners, handle temperature control of the bath, and
provide ame status outputs and a variety of ESD (emergency shutdown) inputs.
The BMS-2000 is typically installed together with a Pilot Pro™ Series Ignition Assembly. These igniters
are designed and built around the features of the BMS, allowing the BMS to light and maintain a pilot
ame using the sensor that is incorporated into the pilot ignition module, providing ame verication.
The Combustex BMS-2000 is suitable for both new installations and retrotting older vessels, and is not
limited to Pilot Pro™ igniters.

1.2 BURNER SEQUENCING
When initiating a start sequence, the BMS will open the pilot and energize the igniter for the trial for
ignition period and wait for the ame sensor to conrm a ame. Upon ame verication, the unit will
then go into “Normal Operation”. At this point, the BMS will energize the main burner and the ame
status output(s). The temperature control option will also become enabled (if congured).
Set points and the associated password protected timers are congurable in the BMS menu. Other
congurable options:
• Purge and Pre-purge
• Auto Relight on Flame Fail
• Auto Relight on Power Fail (unit will relight when power is restored)

• Burner 1 operates only (see P&ID drawings pp. 31 - 15).
• Burner 2 operates only.
• Parallel - Dual Burner System. Both burners will run independently of each other
• Series - Dual Burner System. Both burners will shut down on any single ame fail.
This value represents the rst level of the ame proving sequence for burner #1 if“Flame Detection” is
congured to Thermocouple. Main burner #1 is allowed to open after crossing this set point. Preset at
250°C (482°F).
This value represents the nal level of ame verication for burner #1 if “Flame Detection” is congured
to Thermocouple. Burner #1 will go into Normal Operation upon crossing this set point. Preset at 450°C
(842°F).
This value represents the rst level of the ame proving sequence for burner #2 if“Flame Detection” is
congured to Thermocouple. Main burner #1 is allowed to open after crossing this set point. Preset at
250°C (482°F).
This value represents the nal level of ame verication for burner #1 if “Flame Detection” is congured
to Thermocouple. Burner #1 will go into Normal Operation upon crossing this set point. Preset at 450°C
(842°F).
This value sets the amount of time the BMS will allow for the Flame Sensor to verify a ame. If the ame
sensor does not send signal to BMS verifying a ame in the prescribed time, the ignition sequence is
halted. Preset for 10 seconds on contact input.
