A Study on the Development of Pretreatment System to Incinerate Waste Oil with Sludge in Boilers

Various waste oil such as that from the oily water seperator, the fuel and lubricating oil purifier and leakages from machinery is gathered into the waste oil reserve tank of recent ships while she is in operation. The ship's engineers burn them out with the waste oil incinerators to empty the reserve tank at sea. But usually it takes many hours to incinerate some hundereds or more liters of the waste oil a day due to the fact that the incinerators have available capacities of only twenty or more liters an hour. In addition, the incomplete mixture of oil, sediment and water in the waste oil results in the possibility of choking of the pipe line system and the atomizers as well as destabilizing or extingushing the flames. Accordingly, many engineers on board ships do not like to operate the waste oil incinerators. Therefore, the actual validity of these incinerators for anti-pollution of the sea should be examined on the basis of whether the equipments are used in practice or not. If they are, are they being operated appropriatly? The author develops a reformming system of the waste oil with the sludge to incinerate waste oil in the furnaces of auxiliary boilers. He also examines the performance characteristics, and verifies that the system has the ability of incinerating the waste oil with the sludge in the furnaces satisfactorily without emmissing remarkable soot from exhaust gas. Thus he concludes that it could afford to save the fuel oil for the boiler as well as dramatically increase the incinerating capacity.
