Title:
EXHAUST GAS PURIFICATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2010/092855
Kind Code:
A1
Abstract:
In a machine wherein a plurality of diesel generators are driven such as a marine vessel, a switching operation from a low-sulfur fuel to a general fuel loaded on the machine (and vice versa) is simplified. An exhaust gas purification system which is equipped with a NOx catalyst (62) accelerating the reduction of NOx contained in an exhaust gas from a plurality of electric power-generating engines (12), a urea-water injection nozzle (47) supplying urea-water for reducing NOx to the exhaust gas, and an electric power transducer (15) detecting the concentration of NOx in the exhaust gas on the basis of the electric power generation by electric power generators (13) that are driven by the electric power-generating engines (12). The system is further equipped with an engine controller (80) controlling the driving of each of the electric power-generating engines (12) and a supply-switching electromagnetic valve (81) selectively switching a low-sulfur fuel to a general fuel (and vice versa) as the fuel to be supplied to each of the electric power-generating engines (12). The system is designed so that the engine controller (80) controls the switching by the supply-switching electromagnetic valve (81).
