Annexes
­ Luftreinhaltegesetz and Luftreinhalteverordnung für Kesselanlage (Clean Air Act and
Clean Air Ordinance for Steam Boilers) (LRG-K and LRV-K)
In Austria emissions from steam boiler plants and waste heat boilers are regulated by the
“Luftreinhaltegesetz für Kesselanlagen” (BGBl. 1988/380 i.d.F. BGBl. 1993/185, BGBl. I
1997/115, BGBl. I 1998/158) and the ordinance “Luftreinhalteverordnung für Kesselanlagen”
(BGBl. 1989/19 i.d.F. BGBl. 1990/134, BGBl. 1994/785, BGBl. II 1997/324). The
emission standards for dust, SO2, CO and NOx due to the Luftreinhalteverordnung für Kesselanlagen
depend on the kind of fuel and on the thermal output of the plants.
Dust emission standards [mg/Nm 3 Fuel

Capacity a [MW]
50 MW
Solid fuels b
150 50
Gaseous fuels - 5 5 5
Heating oil extra light - 30 30 30
Heating oil light - 50 35 35
Heating oil medium - 60 50 35
Heavy fuel - 60 50 35
a
The capacity is defined as the average of the hourly added amount of heat related to the calorific value of the
fuel
b Wood is excluded

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 solid fuels are related to 6 % oxygen in the exhaust gas. For liquid and gaseous
fuels they are related to 3 % oxygen. All emission values are related to dry exhaust gas at 0 °C and a pressure
of 101.3 kPa.
Emissions to Water
The discharge of waste water into surface water or the public sewerage system in Austria is
regulated by the ordinance “Allgemeine Abwasseremissionsverordnung” (General Waste Water
Emission Ordinance) (BGBl. 1996/186) and special ordinances for different industrial sectors.
