Energy saving analysis of airport ground bridge-brone equipment

Calculates and analyses the replacement of aircraft auxiliary power unit(APU) by airport bridge-borne equipment from the aspects of energy consumption, emission reduction and economic benefits based on obtained data from literature review and enterprise research. Taking a domestic airport as an example, records the number of planes, aircraft types, flight natures and number of bridges in one day and analyses different types of bridge-borne equipment in each boarding bridge. The results show that at the maximum power of bridge-brone equipment, the energy consumption ratio of bridge equipment to APU is no more than 32%, and the annual energy saving rate of the airport can reach 81%. The airport can reduce CO2 emission by 39 300 tons on statistics day, with 77.39% of the reduction rate. Airports and airlines can achieve win-win effect in economic benefits.
