Xi'an Gaoling Waste Incineration Power Plant: SIL Pressure Transmitters Ensure Incinerator Safety
2026/05/28
Project Background:
The Xi'an Gaoling waste incineration plant operates three large-scale incinerators. Flue gas pressure is directly linked to explosion risks and falls under a SIL3 safety loop, requiring regular calibration and documentation.
Key Challenges:
- Flue gas contains dust and sulfur, making it highly corrosive;
- Manual calibration of safety instruments (SIL) is labor-intensive and prone to errors;
- Clogged impulse lines lead to false alarms and unplanned shutdowns.
Selected Products:
Cerabar PMC71B / PMP55 pressure transmitters featuring ceramic diaphragms, SIL Guide, CRC checksum, and HART communication.
Application Results:
- Ceramic diaphragm offers excellent wear and corrosion resistance, achieving 99.98% availability;
- SIL Guide enables one-click safe parameter verification, reducing calibration time by 80%;
- CRC checksum prevents accidental parameter changes, enabling traceable safety audits;
- Built-in clogging warning function reduces unplanned shutdowns by 70%.
