Reducing CO_2 from ships

摘要

For example, during 2009 AalborgrnIndustries received numerous orders for waste heat recovery (WHR) plants. These will contribute significantly to the reduction of CO_2 emissions for ships in operation through the recovery of the energy wasted in the exhaust from the large diesel engine and using this for electrical power generation.rnToday, the main engine of a ship has a thermal efficiency of approximately 50% (the best coal-fired stations show an efficiency of 45%). This impressive efficiency is the result of many years of intensive R & D work carried out by engine builders.
