Siemens LFL1 122 Flame Detector
Technical specs, application notes, replacement checks, and related model references.
Product Overview
The Siemens LFL1 122 is a heavy-duty automatic burner control unit specifically designed for forced draft gas, oil, or dual-fuel burners of medium to high capacity. It features a robust mechanical cam switch design to manage complex ignition sequences, pre-purge phases, and precise flame supervision in demanding industrial environments. This controller is a staple in industrial boilers, large furnaces, and process heating plants where continuous, safe, and controlled combustion is non-negotiable. It guarantees proper air damper control, fuel valve sequencing, and automatic lockout under abnormal conditions. Built for endurance, the LFL series is recognized globally for its fail-safe mechanical reliability, longevity, and adherence to rigorous industrial burner safety protocols.

Selection Notes & Data Verification
The LFL1 122 page is structured for engineering comparison: confirm the product type, firing range, fuel type, operating mode, electrical supply, and safety approvals against the manufacturer datasheet before specifying the burner or component.
Burner.wiki normalizes product data for discovery and comparison, but final selection should account for combustion chamber backpressure, local emission limits, control sequence requirements, and site commissioning conditions.
