Comparison of measuring results between solid fuel stoves tested in accordance with EN 13240 and NS 3058

5. Theory

It is expected that there will be a direct connection between the particle emission and the CO value.

After the stoking in a test charge there will be a period of time before the flames will arise, and before the combustion seriously gets going. Notoriously there will be a high CO value in this period of time during the EN test and a correspondingly high particle emission during the NS test.

In the end of a test period, when the fire goes out, there will also be a relatively high CO value, whereas the particle emission presumably is insignificant. However, the amount of CO is from the start-up normally higher than from the end, so totally there ought to be a connection between high CO values and high particle emissions.

A similar connection exists between THC/OGC (tar material – measured according to FID measuring method) and CO.
