Oil preheater

An oil preheater is a unit or a component that warms fuel oil to improve its viscosity. The oil preheating process is used, for example, when firing heavy oils, as the viscosity of those oils is not suitable for atomisation by the burner nozzles. Light fuel oil is also preheated in low-capacity burners, such as the WL5-purflam®, so that fine atomisation of the oil can be ensured even after long periods of inoperation or in low ambient temperatures. Benefits include a lower fuel throughput (and therefore lower ratings), improved combustion with reduced emissions, and an improved burner start.
