The burner block library for TIA Portal supports you in the creation of furnace or burner systems with oil, gas and hydrogen burners in single or multi-burner operation..
Components of a burner solution
A burner automation solution involves interaction of burner-specific components and various automation and control components:
An essential feature of a furnace and burner system is the interaction between the fuel supply and the combustion air. These manipulated variables can be controlled using various concepts (e.g. mechanical or electronic compound):
Mechanical compound
In a mechanical compound, only one actuator (air) is equipped with an actuator or pneumatically via a pressure line. The second actuator (e.g. for air) is mechanically connected by a rod. During commissioning, these units are then adjusted to the prevailing pressure conditions. However, the rigid dependence of the actuators on each other has its limits in terms of controllability. Different combustion temperatures cause density changes and may require different air-to-gas ratios.

Electronic compound
In an electronic compound, both actuators for air and gas are equipped with their own drives. These actuators operate in a closed loop and the associated feedback circuit signals. Control deviations can be optimally regulated by electronically different specifications for the air and gas actuators. In this way, it is possible to react very flexibly to different gas compositions or to implement a control system based on a flue gas measurement.

Burner block library for TIA Portal
The burner block library for TIA Portal supports you in creating a burner application for gas, oil and hydrogen burners. It is based on the hardware of the SIMATIC S7-1200/1500 F-CPUs with the associated safety I/O modules.
The fail-safe software function blocks with German Technical Inspectorate (TÜV) report represent the core of the burner block library. These have the following range of functions
Standards and guidelines
When designing a burner application, several guidelines and standards must be observed. The control logic needs to meet not only the requirements of EN 62061 or EN 13849-1, but also those of furnace-specific standards.
The burner block library takes into account the following standards to support you in implementing the functional requirements and reduce your workload:
| EN 746-2 | Industrial thermal process plants – Safety requirements for furnaces and fuel systems |
| EN 298 | Automatic burner control systems for burners and appliances burning gaseous or liquid fuels |
| EN 676 | Automatic forced draft burners for gaseous fuels |
| EN 267 | Automatic forced draft burners for liquid fuels |
| EN 1643 | Valve monitoring systems for gas burners |
| EN 12952-8 | Water-tube boilers and auxiliary installations – Requirements for firing systems for liquid and gaseous fuels for boilers |
| EN 12953-7 | Shell boilers – Requirements for firing systems for liquid and gaseous fuels for boilers |
| ISO 13577 | Industrial furnace and associated processing equipment – Safety |
| NFPA 85 | Boiler and Combustion Systems Hazards Code |
| NFPA 86 | Standards for Ovens and Furnaces |
Depending on the type of burner/furnace you have, you may need to have it approved by an independent authority or institution. You can find out whether your system is affected by this in the relevant guidelines and laws. In any case, it is advisable to contact the authority or institution at an early stage of the project.
