| Outline of Final Research Achievements |
The electrostatic precipitator (ESP) with heat exchanger was developed to reduce particles and SO2 emitted from marine diesel engines. The influence of gas cooling on the particle and SO2 concentrations was investigated using a 400-cc diesel engine.The results show that the number and the volume concentration of particles increased due to generated SOF and sulfuric acid particles by gas cooling. It was also indicated that SO2 concentration in the gas was reduced due to absorption into condensed water. Although the particle concentration increased, ESP showed a high particle collection efficiency.
