SOx and PM removal using electrostatic precipitator with heat exchanger for marine diesel
نویسندگان
چکیده
The reduction of SO2 and PM for marine engines was investigated using the electrostatic precipitator (ESP) with the heat exchanger. The experiments were carried out to reduce SO2 due to condensation of water in the exhausted gas. The experimental system consists of the diesel engine, the heat exchanger and the ESP. The exhausted gas at 180 o C of the temperature is cooled to 20 o C, and generated mist particles due to water condensation in the heat exchanger. The mist particles and PM are collected in the ESP. The particle concentrations were measured using the scanning mobility particle sizer and the low volume air sampler after hot dilution. SO2 concentrations are also measured by the SO2 monitor using UV fluorescence after hot dilution. As a result, the condensation water was sampled after the heat exchanger. SO2 removal rate was 76 %, and the collection efficiency was 78% in ESP with the heat exchanger.

Low resistive particulate matter (PM) generated from marine engines or diesel generators has been known to be difficult to collect by the conventional electrostatic precipitators (ESP). In the present study, the double-cylinder type ESP (DC ESP) was developed to remove low resistive diesel exhaust particles. Two ESPs, namely, the conventional singlecylinder type ESP (SC ESP ) and DC ESP were in...
