Oil emerging from a storage tank and containing all forms of pollution is placed in extensive surface contact with an underlying washing liquid having a greater specific gravity, on to which it diffuses, gives up to it material soluble therein and, in the absence turbulent flows causes solid particles to sink into it after which it rises up and makes room for newly-arriving contaminated oil. This process is supported by its performance in the boiler chamber so that the oil is heated during the operation; in addition, this heating reduces viscosity and leads to improved atomization in the burner. The device (1) consists of a vessel, closed off by an inspection window not illustrated, said vessel having an inner chamber (2) containing, up to its surface (7), the washing liquid (5) i.e. water with or without additives; the oil enters through an inlet port (3) and emerges from the vessel at the top through a discharge opening (4). |
