Annexes
There are four different kinds of heating oils in Austria. The sulphur content in the different kinds
of heating oil is laid down in the ‘Verordnung über den Schwefelgehalt von Heizölen’ (BGBl.
1989/94 i.d.F. BGBl. 1994/545). The following table presents the maximum sulphur content in different
kinds of heating oil in Austria.
Maximum sulphur content of different kinds of heating oil
Type of heating oil Maximum sulphur content
Heating oil extra light 0.10 wt.-%
Heating oil light 0.20 wt.-%
Heating oil medium 0.60 wt.-%
Heavy fuel 1.00 wt.-%
For the lowest capacities of firing installations, the quality of heating oils to be used is restricted.
Heating oils with a higher sulphur content may be used in an installation with a
lower power capacity if the SO2 emission levels in the following table are guaranteed by
other measures.

The capacity is defined as the average of the hourly added amount of heat related to
the calorific value of the fuel
Some of the emission standards are different for the different kinds of heating oil. The following
four tables present the emission standards for dust, SO2, CO and NOx in oil-firing
plants.

The capacity is defined as the average of the hourly added amount of heat related to the calorific
value of the fuel
The emission standards for liquid fuels are related to dry exhaust gas at 0 °C, a pressure of 101.3 kPa
and an oxygen content of 3 % in the exhaust gas
The emission standards for SO2 and CO are related to the thermal output of the firing
plants.
