TS prEN 267

TS prEN 267 is a standard dealing with definitions, requirements, test principles and marking for forced draught oil burners. Its specific technical focus is on burners supplied with fuel whose viscosity at the burner inlet is between 1 mm²/s and 6 mm²/s at 20°C, linking fuel properties directly to burner design and testing concerns.

Technical scope of forced draught oil burners

In a forced draught burner, combustion air is supplied by a fan or similar mechanical device. This gives tighter control over flame formation and stability, which is why such burners are widely used in boilers, process heating equipment and other heat-generating installations. For liquid fuels, viscosity is a key variable because it influences atomization, spray formation and mixing; the stated fuel range therefore has clear technical significance.

Testing, laboratory assessment and marking

The standard covers test requirements and methods for laboratory testing. In general technical terms, such provisions are intended to make performance, reliability and core operating characteristics of a burner assessable under controlled conditions and in a comparable way. The marking aspect identified in the title is important for product identification and correct application, but this record should be understood as addressing this technical field rather than reproducing the full content of the complete document.

• The standard applies to forced draught oil burners.
• It covers fuels with viscosity at the burner inlet of 1 mm²/s to 6 mm²/s at 20°C.
• It includes laboratory test rules and test methods.
• Definitions, requirements and marking are named in the title.
• This record refers to a withdrawn TSE standard based on prEN 267:1996.
