Intake air cooling apparatus for stationary internal combustion engine

摘要

A water-saving intake air cooling apparatus for a stationary internal combustion engine includes a primary intake air cooler, a high temperature side intake air cooler, and a low temperature side intake air cooler in an intake air passage upstream and downstream of a turbo charger. A first radiator transfers cooling water to an absorption chiller. The absorption chiller transfers cooling water to the primary intake air cooler and to the low temperature side intake air cooler. A second radiator transfers cooling water to the high temperature side intake air cooler. A third radiator cools lubricating oil flowing through a lubricating oil circulation space. Steam is generated by an exhaust heat boiler provided in an exhaust gas passage, and the steam is supplied to the absorption chiller as a heat source. Such use of the first, second, and third radiators, reduces the need for cooling water.

主权项

1. An intake air cooling apparatus for a stationary internal combustion engine in which a turbo charger is provided in an intake air passage and an exhaust gas passage, comprising:
a first intake air cooler provided in the intake air passage on an upstream side of a compressor forming the turbo charger in order to perform primary cooling on intake air; a second intake air cooler for performing secondary cooling on the intake air on an outlet side of the compressor after the intake air is compressed and heated by the compressor; an absorption chiller that uses heat possessed by exhaust gas from the stationary internal combustion engine as a heat source and supplies cooling water for cooling the intake air to the first intake air cooler and the second intake air cooler; and a heat exchanger that cools cooling water by performing heat exchange between the cooling water and outside air and supplies the cooling water to the absorption chiller as a cold source, wherein intake air supplied to a combustion chamber of the stationary internal combustion engine is cooled by the first intake air cooler and the second intake air cooler.
