Abstract
An exhaust gas released from the exhaust gas heat exchanger 9 is conveyed into the inlet of a bend 32 communicated to a silencer 31. The exhaust gas mixed with the condensed water is upwardly passed as a mixture fluid through a passage 322 and forced into a first expansion chamber 323. The mixture fluid is separated into the exhaust gas and the condensed water in the chamber 323 and conveyed downwardly in a passage 324 provided with a second expansion chamber 325. While the exhaust gas is forced upwardly from the lower end of the silencer 31, the condensed water is discharged downwardly. The condensed water is conveyed in the drain passage of a waster water trap and released to the outside.
Claims8
An engine waste heat recovering apparatus having an exhaust gas heat exchanger for recovering heat from the exhaust gas of the engine and a drain passage for discharging the condensed water produced due to the function of heat exchange in the exhaust gas heat exchanger, comprising:
- a lift-up passage extending upwardly from the exhaust gas heat exchanger;
- an expansion chamber communicated with an upper end of the lift-up passage;
- a fall-down passage extending downwardly from the expansion chamber;
- and
- an exhaust gas discharge passage communicated with a lower end of the fall-down passage extending upward, wherein the drain passage is communicated at its bottom.
