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.
1.7

Warning plates on the turbocharger

Warning plates that must be observed are attached to the turbocharger. The warning plates
must always be present in the intended locations and must be legible.
Figure 1: Warning plate
If warning plates are not present in the intended locations or are not legible, they must be re-
placed with new warning plates. The information that is required can be found in the Operation
Manual / Product description.
Turbochargers supplied to the enginebuilder without insulation must be equipped later with
warning plates on the insulation. This is the responsibility of the enginebuilder.
