Abstract (en)

[origin: EP2489843A1] Problems in conventional exhaust gas treatment techniques for a diesel engine that use corona discharge are solved, and a method and equipment of electrical treatment for diesel engine exhaust gas are provided which can remove with high efficiency PM, particularly, SOF in exhaust gas of a diesel engine using a low-quality fuel equivalent or inferior to heavy fuel oil, and which can provide long-term stable performance. In an electrical exhaust gas treatment method for a large-displacement diesel engine that removes, by an electrical means, particulate matter mainly including insoluble organic fractions and soluble organic fractions contained in exhaust gas of a diesel engine that uses a low-quality fuel equivalent or inferior to heavy fuel oil, the particulate matter is removed by the electrical means after the temperature of the whole exhaust gas containing the particulate matter is lowered by 100°C or more, preferably, 130°C or more, to a temperature that is represented by a ratio R of exhaust gas temperature/fuel boiling point temperature of 0.85, or less by a gas cooling means.
