Vacuum Boiler – Natural Gas Line
CWT Boiler, Dry Line Heater, Pipeline Heater, Vacuum Boiler
After consulting with National Grid, the Profire Team recommended a PF3100 burner management system for the application. The PF 3100 platform provides a wide range of temperature control, process and ESD functions. The proposed solution included a Profire ignition electrode to allow automatic pilot re-lighting and reliable pilot flame detection. The system was further optimized for efficiency and reliability by the following changes:
- Replacement of the existing temperature switches with Type K dual head thermocouples
- Replacement of the millivolt operated gas valves with Asco solenoids controlled by the PF3100 controller
- Replacement of the existing vacuum switches with vacuum transmitters to allow connection to the PF3100
- Enabled Modbus features on the PF3100
National Grid was able to dramatically improve reliability, safety, and visibility of their vacuum boiler operation after the upgrades. The company can now easily view live heater conditions and adjust set points both onsite and remotely.
