Abstract

Nowadays, the use of exhaust gas energy seems to be a very promising key to increase the energy efficiency in maritime field by converting the thermal losses of ship into useful energy sources such as exhaust boiler, exhaust turbo charging or mini electrical generator, which ensure the best utilization of the fuel, reduce emission met IMO requirements and reduce the operating costs. Diesel engine exhaust gas energy, certainly the most interesting among the waste heat sources of a ship because of the heat flow and temperature, is always considered to utilize due to the exhaust gas energy is approximately 25-30% of total energy of burned fuels in internal combustion engines. By installing the main propulsion plant with a waste heat recovery system (WHRS), the fuel can be utilized more economically, because energy lost in the exhaust gas flow is less. Moreover, the amount of CO2 emissions related to the mechanical power output of engines may be dropped off. The paper presents the review of utilization of exhaust gas heat in ship and suggests a heating up method for biodiesel or bio-oils which fuel in diesel engine in order to get dual benefit.

船用柴油机废气回收以减少有毒排放物和节约能源:一个小回顾

目前，将船舶的热损失转化为有用的能源，如废气锅炉、废气涡轮增压或微型发电机等，以确保燃料的最佳利用，减少排放，达到IMO要求，降低运营成本，是提高海事领域能源效率的一个非常有前途的关键。柴油机废气能量是船舶废热源中最有趣的一种，由于其热流和温度的关系，柴油机废气能量约占内燃机燃烧燃料总能量的25-30%，因此一直被认为是可利用的。通过安装带有废热回收系统(WHRS)的主推进装置，可以更经济地利用燃料，因为废气流中的能量损失更少。此外，与发动机的机械功率输出有关的二氧化碳排放量可能会下降。本文综述了船舶废气热利用的研究进展，提出了一种对柴油发动机中的生物柴油或生物油进行加热的方法，以达到双重效益。
