To reduce oxidized metals in exhaust gas and prevent the corrosion of equipment due to metal fused salt by supplying to a diesel engine a heavy oil from which metals are removed using high-temperature and high-pressure water.
An oil reformer consisting of a reactor for desorption reacting metals with the mixture and reaction of supercritical water, heavy oil and oxidant and a trapper for removing the metals after desorption from a liquid with a trapping agent is installed on the upstream side of a fuel supply system for the diesel engine. The high-temperature and high-pressure water and the oxidant are used for the desorption of the metals from the heavy oil and trapping them with the trapping agent. The heavy oil from which the metals are removed is supplied to the diesel engine, thus reducing the oxidized metals in the exhaust gas and preventing the corrosion of the equipment.
