The soundtrack was also processed with volume normalization, noise reduction, clipping reduction, and equalization (the resulting sound, though not perfect, is far less noisy than the original). US Navy Training Film MN-9223f en.wikipedia.org An oil burner is a heating device which burns fuel oil. The oil is atomized in to a fine spray usually by forcing it under pressure through a nozzle. This spray is usually ignited by an electric spark with the air being forced through by an electric fan. Fuel is injected into the combustion chamber by a spray nozzle. The nozzles are usually supplied with high pressure oil. Because of problems with erosion, and blockage due to lumps in the oil, they need frequent replacement typically every year. Fuel nozzles are usually rated in fuel volume flow per unit time eg USGal/h (US Gallons per hour). A fuel nozzle is characterized by 3 features: - A flow of 7 bar pump pressure (0.65 (USGal / h)) - The spray characteristic (S) - The spray angle (60 °) Alternatively fuel may be passed over a tiny orifice fed with compressed air. This arrangement is referred to as babington atomiser/nozzle after its inventor. As the oil flows over the nozzle , the fuel needn't be under any great pressure. If the pump can handle such the oil may even contain lumps such as ...
