Nitrogen Generation System Boeing

The aersafe system limits the amount of available oxygen that can ignite fuel vapors and prevents sparks from initiating an explosion. Nitrogen generators are used in hypoxic air fire prevention systems to produce air with a low oxygen content which will suppress a fire. Paragraph h of this proposed ad provides that for operators not required to comply with the ftfr rule electing to comply with the ftfr rule would be an acceptable.

There is no chemically new nitrogen created.

Nitrogen generation system boeing.

Boeing 747 nitrogen generation system ngs controller. Projected annual electrical costs would have been 76 400 including peak demand charges. Packages can be either skid mounted or free standing depending on local requirements. Aversan system integration lab avsil avsil is an affordable flexible system integration solution for real time closed loop.

The projected energy consumption for a system equivalent to boeing s original nitrogen generator but with higher capacity was an estimated 2 150 000 kwh per year with a peak each month of 225 kw. Operators of airbus 319 320 321 and boeing 767 and 737 aircraft have two options. Typical high pressure psa system 40 350 bar g parker nitrogen gas generation systems are designed to deliver high purity high pressure nitrogen gas eliminating the need for delivery of costly high pressure cylinders. To prevent corrosion nitrogen generators are used in place of or in conjunction with a compressed air system to provide supervisory nitrogen gas in place of air for dry pipe and pre action fire sprinkler systems.

Aversan provided embedded test software for the boeing 747 nitrogen generation system. These include cabin pressurization compressor motors ram air fan motors the nitrogen generation system compressor used for fuel tank inerting and large hydraulic pump motors. The nitrogen generating system ngs being developed by boeing to meet the ftfr rule addresses the unsafe condition of this ad as well as providing other safety improvements. A flammability reduction means such as nitrogen inerting or an ignition mitigation means such as aersafe.

The 270 vdc system supports a handful of large rated adjustable speed motors required for the no bleed architecture. As rac points out nitrogen generation system is somewhat of a misnomer all the system does is remove oxygen from the ambient air and blow the rest into the center fuel tank.
