Use of ABB turbochargers on gas engines

ABB turbochargers can tolerate a deflagration with a transient pressure increase of 12 bar. In
deflagration tests on engines with flame barriers, a maximum of 11 bar was measured. This
value is supported by the practical experience in operation gained by renowned gas engine
manufacturers. ABB turbochargers have never been damaged in the past when deflagration
events occurred.
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.
