民用航空器机载APU污染排放及节能运行研究

Pollution Emission and Energy-saving Operating for Airborne APU

针对当前民航机场飞机经停、维修、航前航后普遍使用机载APU的现状,研究减少APU使用的必要性和可行性。经广泛调研搜集APU运行数据,并对数据进行分析计算,得出机载APU运行所造成的大气污染和燃油消耗情况。研究表明,某航空公司一年中APU消耗燃油约5万t,CO2排放总量约15万t左右,其他污染物的排放也达到数百吨。通过对机坪内机载APU运行噪音的监控表明,APU的运行噪音最大达到94.7 dB,因此,减少机载APU的使用是十分必要的。并参考国外机载APU的运行情况,提供机载APU节能运行模式的方案。

Concerning the APU generally used in civil airport for aircrafts stopover and being maintained between flights, necessity and feasibility of reduction of APU use were studied. Based on analysis of a large number of APU operation data, air pollution and fuel consumption caused by APU operation were analyzed and calculated. Results indicated that some airline APU fuel consumption was about 50,000 tons in a year, CO2 emissions about 150,000 tons, and emissions of other pollutants reached hundreds of tons. APU running noise monitoring showed that APU operating noise was up to 94.7 dB, therefore re- ducing the chance of using APU is very necessary. With the reference to operation mode of foreign APU, the program of air- borne APU energy-saving operation mode was also provided.
