A device for utilizing the waste heat of a thermo-process device comprising a first heat exchanger for transferring heat from a heat flow of a thermo-process device to a heat transfer medium; a second heat exchanger for transferring heat from the heat flow to a heat transfer medium, the second heat exchanger being arranged downstream of the first heat exchanger with respect to the heat flow; a thermodynamic cycle device having a third heat exchanger for transferring heat from the heat transfer medium to a working medium of the thermodynamic cycle device and having a fourth heat exchanger for transferring heat from the heat transfer medium to the working medium, the fourth heat exchanger being arranged upstream of the second heat exchanger with respect to the flow of the working medium; wherein heat transfer medium cooled in the third heat exchanger can be supplied at least partially to the first heat exchanger for heating and wherein heat transfer medium cooled in the fourth heat exchanger can be supplied at least partially to the second heat exchanger for heating.

An EGR cooler 5 is attached to an engine 1 via a bracket 6. The bracket 6 has an exhaust introduction path 65 for introducing some exhaust discharged from a cylinder head 11 to the EGR cooler 5, an exhaust recirculation path 66 for recirculating exhaust that has passed through the EGR cooler 5 toward the engine 1, a cooling water introduction path 67 for introducing cooling water from cooling water supply parts (3, 13-15) to the EGR cooler 5, and a cooling water recirculation path 68 for recirculating cooling water that has passed through the EGR cooler 5 to the cooling water supply parts.

A cooling system is mounted on an internal combustion engine equipped with an EGR device including an EGR passage. The cooling system includes: an intercooler disposed in the intake passage; an EGR cooler disposed in the EGR passage; a condensed water discharger configured to discharge condensed water generated in the EGR cooler from the EGR passage; a radiator configured to cool a first coolant to or below a dew point of the EGR gas flowing into the EGR cooler; a first circulation flow path configured to circulate the first coolant in the order of the radiator, the EGR cooler, and the intercooler; and a pump disposed in the first circulation flow path and configured to circulate the first coolant such that an outlet gas temperature of the EGR cooler is equal to or lower than the dew point of the EGR gas flowing into the EGR cooler.

An exhaust gas recirculation (EGR) system with a diesel particulate filter (DPF) incorporated before the EGR cooler to filter the particulate matter from the EGR before entering the air intake. With the DPF installed before the EGR cooler soot buildup in all EGR components and air intake track is reduced or eliminated. Installing the DPF before the EGR cooler allows the DPF to be in passive regeneration while the vehicle's engine is in operation, extending the life and maintenance interval of the DPF. Alternatively, the DPF may be installed after the EGR cooler, reducing or eliminating soot buildup in the EGR valve and air intake.

The present invention relates to an apparatus for reducing greenhouse gas emission in a vessel cooperated with exhaust gas recirculation (EGR) and intelligent control by exhaust recycling (iCER), and a vessel including the same, in which EGR and iCER are combined so that NO.sub.x generation is reduced by EGR and CO.sub.2 and SO.sub.x are absorbed and converted into materials that do not affect environments, thereby preventing corrosion of an engine, improving combustion quality, increasing engine efficiency by iCER, and reducing methane slip.
