EJECTIVE SYSTEM FOR AIR COOLING OF ALTERNATOR AND ZONAL VENTILATION OF SHIP ENGINE ROOM 

A.N. Radchenko

The efficient ejective systems for air cooling of alternators and local ventilation of ship engine room in the zones of diesel-generator displacement with increased intensity of heat emission. The circulation of air in ejective systems is performed by using the energy of exhaust gases of driving diesel engine. With this the circulation of ventilation air is performed without of energy consumption. Ejective systems can be applied for ventilation of alternator with air from the ship engine room and air cooled by waste heat recovery cooling machine. The pressure-circulation characteristics of ejective devises and schemes of ejective systems are presented.

Key words: ventilation, ejection, alternator, diesel, diesel-generator, utilization, exhaust gases, pressure increase.
