Temperature Guideline for HFO

At low exhaust gas temperatures from engines running on Heavy Fuel Oil (HFO) unburned hydrocarbons may condensate and accumulate on the surface of the catalysts. These deposits can not be removed by a dust blower since it is designed to remove dry deposits only.

If the converter reaches from time to time sufficiently high temperatures (above 340°C) possible deposits will evaporate.
