IMPROVEMENT OF THE FLUE GASES CLEANING SYSTEM AT SHIP POWER PLANTS

М. В. Голубев

Abstract


Purpose. In the article there was considered the problem of the flue gases cooling and cleaning from harmful toxic components. There was described the classification of the various methods of cleaning and shown that it is necessary to develop a new method which would be characterizing as a simple and cheap.
Design/methodology/approach. It was offered to use the hydrodynamic process of contact interaction between flue gases and stationary liquid. Due to the specially profiled camera settings has been achieved an increase in residence time of flue gases in the water. There was done a description of the main aspects of water-gas filtration theory and given an explanation of some features of the hydrodynamic behavior of a gas bubble during flotation process.
Findings. On the basis of the stated differential equations solution there was obtained a number of theoretical results, which describe the dynamics of interaction between flue gases and water. All results were obtained using the finite difference method. The description of the results of physical experiments, performed in real marine environments. There was done a description of the influence of the flow’s velocity at the inlet to the plant onto the heat take-off process and concentration reduction of oxides of sulfur and nitrogen.
Originality/value. Exactly for the ship operating conditions there was developed a method of calculation of the separation unit and had been formulated general conclusions.


Keywords
