    Combustion properties of various pyrolysis oils were studied at Oilon (Lahti, Finland) in a test boiler on 4 MW output level. Burner settings and boiler dimensions as well as oil properties were tested. A special emphasis was on oil specifications for boiler application. It was concluded that pyrolysis oils can be combusted in slightly modified conventional oil furnaces and boilers fairly well. Some existing oil burners are also capable to combust pyrolysis oils, but they might need slight modification. However, oil specifications must be defined, including at least water and solids. Special care should be taken in handling and pumping of oils. Support fuel is needed at the burner to start the combustion and recommended for supporting pyrolysis oil in case of poor-quality oil. Emissions depend on oil quality. They are generally equal to those of light fuel oil or light bunker oil, but the content of particles in exhaust gases is higher. The results are applicable with small modifications in the boiler size class down to 1 MWth. Research into replacing light fuel oil in boilers below 1 MWth continues.
