Furnace Safety Supervision System
Boiler Furnace Safety Monitoring System, or FSSS (Furnace Safeguard Supervisory System), is to ensure the safe operation of boiler-critical systems, which started in the boiler, and stop running all stages of continuous monitoring of the boiler operating parameters, in accordance with provisions of Ex order security conditions, continually carry out logic judgment and calculation, the corresponding interlock device through the combustion facilities in accordance with established procedures to complete the necessary operations to avoid explosive air - in the fuel mixture accumulated inside the furnace and flue, and boiler in the event of endangering the safety of working conditions , entered the chamber quickly cut off all fuel to prevent the occurrence of explosion of a furnace.
Furnace Safety Monitoring System (FSSS) mainly by the operating station, operation panels, the main control cabinet, ignition control system, flame detector and cooling air system, and other components. Including the fuel system, throttle bodies monitoring the implementation, chamber pressure, drum level, the blower fan which, by the door, and other signal conditioning warm water monitoring, as well as with DCS communications. System structure indicative figure: -Main fuel tripping MFT (Main Fuel Trip) -Fuel oil Trip OFT -Oil leak test system -Oil combustion system management (signal detection and control) -Pulverized coal combustion system management (signal detection and control) -Rapid load-shedding Fast Cut Back -Signal detection and extinguishing the flame protection -Alarm and display (node failure, the furnace pressure drum water level alarm limits, combustion instability alarm.) -Flame detector cooling wind management -Controlled ignition (Local / Remote) -Accident causes chronicles functional movements -Recollections functional simulation curve
