Stor, langsomt kørende, turboladet, intern totaktsforbrændingsmotor med længdeskylning og med krydshoveder samt dampturbine

摘要

A large slow running multi cylinder turbocharged two stroke uniflow internal combustion engine with crossheads (53) has a plurality of cylinders (l) that are each connected to an exhaust gas receiver (3) that receives the exhaust gas from the cylinders (l) and to a scavenging air receiver (2) that supplies scavenging air to the cylinders (1). The engine has a turbocharger (6) with an exhaust gas driven turbine (8) that drives a compressor (7) for pressurizing the scavenging air, an exhaust gas conduit (18) connecting the exhaust gas receiver (3) to the turbine (8), a scavenging air conduit (11) connecting the compressor (7) to the scavenging air receiver (2) and a water based engine cooling system. The engine further comprises a heat exchanger (14) for heating the scavenging air, the heat exchanger (14) being arranged upstream of the compressor (7) and the heat exchanger (14) being heated with cooling water from the engine cooling system, and an evaporating or superheating and evaporating boiler (13) arranged in the scavenging air conduit (11) with scavenging air flowing through the evaporating or superheating and evaporating boiler (13), and a s team turbine (37) powered by steam delivered by the evaporating or superheating and evaporating boiler (13).
