Abstract

Based on a 260 t/h ultra-high-temperature subcritical gas-fired boiler power generation project at a steel plant, this paper designs a Boiler Furnace Safety Supervision System (FSSS) utilizing Siemens TIA Portal configuration software, WinCC monitoring software, and S7-1500 PLC hardware. The system incorporates key functional modules such as the Main Fuel Trip (MFT), furnace purging, first-out fault memory, and boiler ignition control. Actual unit operation has verified the comprehensive functionality of this FSSS system, providing valuable design and operational reference experience for similar boiler safety monitoring applications.
