Burner Management

Burner Management Systems (BMS) and Fuel Safety Systems (FSS)

FPS is one of very few companies in the world that can supply a Burner Management System with a full complement of boiler safety products. Our safety systems are typically supplied including control cabinets, flame scanners, ignitors, valve trains, blower assemblies, and water level detectors, all of which are designed, built and tested in our factory. Over the past twenty years FPS has continually developed and improved upon our product line, and we now support one of the largest users list of BMS, and BMS products, in North America.

The Burner Management System is the safety and sequencing system used when firing boilers. The BMS common logic includes fan control, power monitoring, boiler purge, boiler trip, firing permissive and furnace implosion/explosion protection. The fuel portion of the logic includes fuel headers and/or coal distribution systems, ignitor control, burner control and air register control. When required, the BMS also includes the PA duct heaters and fuel lean gas reburn (FLGR) systems. Additional features that are available include automatic fan runup, automatic coal mill startup and shutdown sequencing, and automatic burner start/stop for load varying boilers.

Some standard features of FPS’s BMS include a fully redundant, hardwired Master Fuel Trip circuit, which is in full accordance with the latest NFPA 85 code. First out and "cause of trip" annunciation, alarming, and sequence of events monitoring are also included with each system.

Emergency Shutdown Procedure (ESP)

In some cases, an additional level of safety is required over and above the traditional safety system. In these instances a hardwired ESP is implemented. An example of one such case is on a black liquor recovery boiler, where an ESP is required in the event of a water or steam leak into the boiler.

FPS has designed an ESP system that is widely used in conjunction with FPS designed safety systems. The ESP provides a means whereby the operator can, in a single operation, shut down the boiler by removing all fuels and place the boiler in a predefined condition to safely remove all combustible gases and isolate any possible source of water or steam.

FPS can engineer, design and manufacture an ESP system either as a single standalone unit, or as an integrated part of a supplied system.
