ABSTRACT

The article presents the results of experimental research carried out on a real object and analysis of the effect of preparing oil-related waste with various physical and chemical properties for combustion in a marine auxiliary boiler, on selected components of exhaust gases, such as carbon oxide (CO), carbon dioxide (CO2) and nitrogen oxides (NOx) arising as a result of their burning. Oil-related waste comes from operating marine power plants; they are characterised by diverse compositions, heterogeneous structure and may contain a large amount of water. They are gathered from various places in the power plant, as also from various vessels, to a single tank on a barge with a fired boiler equipped with burners suited for burning such kind of fuel. For the needs of research, an installation for preparing fuel on the vessel was designed and modernised. The waste is burned after preparation by one of four selected methods permitting the homogenisation of the fuel structure: by gravitational sedimentation, by a homogenising shredder pump, by a static homogeniser constructed at the Maritime University of Szczecin and by a serial connection of these two devices. The experiment was carried out in that exhaust gas composition was measured by means of a portable IMR 3000 P analyser with variable boiler efficiency and using oil-related waste fuel. It was found that the emission of selected exhaust gas components arising at burning oil-related waste depended on the method applied for preparing it for the burning process. It has been shown that the serial connection of the homogenising shredder pump and the static homogeniser has the largest effect on the reduction of toxic compounds contained in exhaust gases.
