Burner Application Example – TIA Portal (Burner Library)
Application Overview
This application example demonstrates a standardised burner control solution using the Siemens TIA Portal Burner Library. It supports the safe operation of gas and oil burners by implementing certified safety functions and modular control logic.
Application Objective
The objective of this application is to provide a reliable and safe burner management system that complies with international safety standards while reducing engineering time through the use of reusable function blocks.
System Description
From a control perspective, the burner system includes air supply, fuel supply, ignition system, flame monitoring, and safety shut-off valves. The application uses Siemens fail-safe PLCs and safety I/O modules to ensure safe operation.
Main Functions
– Air damper control (F_AIRD)
– Gas tightness test (F_TIGHTN)
– Ignition control (F_IGNTR)
– Gas burner control (F_GAS_BU)
– Oil burner control (F_OIL_BU)
– Pre-purge and ventilation (F_PRE_PURGE)
Safety Concept
The application is based on modular safety interlocks, including MAIN_INTL, PRE_INTL, ST_INTL, and OP_INTL. These interlocks ensure that all safety conditions are fulfilled before and during burner operation.
Standards Compliance
The burner application is designed in accordance with major international standards such as EN 746-2, EN 298, EN 676, EN 267, ISO 13577, and IEC 61508 (up to SIL 3).
