Focused Case Retrofit of Aircraft Refueler

Retrofit of Aircraft Refuelers

The Euro III aircraft refuelers of CPC Taiwan Co., Ltd. that refueling aircrafts at Taipei, Taichung, and Kaohsiung International Airports, have been retrofitted with particulate filters for reduction of PM2.5 since 2018.

Operation Mode of Aircraft Refueler

The airport is one of most strictly security and safety control area in every country. Driving speed of all vehicles at the airport must be less than 15 km per hour.
Aircraft refuellers are operated at low exhaust temperature due to slow driving speed at airport when aircrafts refueling.

20,000 liters highly flammable aviation fuel JP-5 is loaded in each aircraft refuellers, that also requires the highest safety procedure of refueling in preventing fire hazards caused by human errors during refueling.

Duty Cycle Assessment (DCA) of Aircraft Refueler.

Daily log of exhaust temperature and pressure after filter installed.

Duty cycle analysis as blow shows profile of exhaust temperature over time in % of daily operation of aircraft refueller for aircrafts refueling.

0.70% of duty cycle, exhaust temperature >240C.
0.00% of duty cycle, exhaust temperature >300C.

Strategy of filter regeneration: Dual Filter Regeneration.

Log of 18 days operation shows maximum exhaust pressure of aircraft refueler is 140 mbar, which is lower than alarm setting.
Partial filter regeneration takes place automatically during daily operation of refueling due to low exhaust temperature, then filter is regenerated by supportive electrical heater monthly to ensure filter being cleaned.
