effects of freshwater on steam boilers

Modern Ships Engine Equipment with Waste Heat

The modern ships engine room equipment includes common rail fuel injection, a waste heat recovery boiler that supplies a steam turbine. The turbine drives a generator that can supply power to motors on the main drive shaft, increasing the efficiency of the plant even more. The exhaust gas emissions of SOx, NOx and particulates are reduced by the use of scrubbers and the efficient engine
