Preliminary remarks

Deflagration on gas engines

State of the art
The turbocharger is designed and built according to the state of the art
and is safe to operate.
Flawless condition
The turbocharger must only be used when it is in a technically flawless
condition and operated in compliance with its intended use.
ABB Turbo Systems excludes any liability for damage resulting from
unauthorized modifications to the turbocharger or improper operation.
Deflagration on gas engines
ABB turbochargers can tolerate a deflagration with a transient pressure
increase of 12 bar.
ABB Turbo Systems recommends subjecting the turbocharger to a visual
inspection after a deflagration event. As part of the inspection, the position
of the turbine casing and the position of the compressor casing to the
bearing casing must be checked, and the bearing casing must be
examined to see if it has shifted in relation to the bracket. A crack
inspection of the casings and the bellows is also recommended. The
nearest ABB Turbocharging Service Station should be instructed to carry
out this inspection and assessment.
