Emission Limits For Dust And Carbon Monoxide (Co) According To 1St Bimschv, Stage 2 (Article 5) - Viessmann VITOFLEX 300-UF Technical Manual

Principles of wood combustion
■ Control of the emission limits for solid fuel boilers with a rated
heating output of 4 to 1000 kW
■ Verification of the required emission limits in the form of periodic
on-site measurements to be carried out by the flue gas inspector
when commissioning new systems (with subsequent periodic
checks every 2 years)
■ Emission limits tightened to 20 mg/m³ for dust and to 400 mg/m³
for CO in the 1st BImSchV, stage 2

Note on dust emission limits
Depending on both the type of fuel used, e.g. wood pellets or wood-
chips, and fuel quality (according to EN ISO 17225) additional emis-
sion reduction measures may be required in order to adhere to the
dust emission limits demanded by the 1st BImSchV.
VDI 4207, Sheet 2 (Emission measurements at small firing installations)
VDI 4207, Sheet 2 (Emission measurements at small firing installa-
tions) specifies the requirements for the initial and periodic testing
and measurement of dust emissions in accordance with the
1st BImSchV or the Kehr- und Überprüfungsordnung (KÜO - sweep-
ing and inspection regulation) when using solid fuels. Also described
are the system and operation-related measures that need to be
implemented in advance in order to ensure that the emissions meas-
urements are carried out correctly.

■ After a transitional period, emission limits will also apply to old sys-
tems.
■ Design of the heating water buffer cylinder in hand charged sys-
tems: Min. 12 litres per litre fuel hopper or 55 litres/kW rated boiler

These are secondary measures, such as a fine-dust filter (e.g. an
electrostatic filter) or tertiary measures in the form of the support of a
Viessmann engineer when measuring. Viessmann should be consul-
ted on this.
