Deflagration on gas engines
2.8
ABB turbochargers can tolerate a deflagration with a transient pressure
increase of 12 bar.
After a deflagration event ABB Turbo Systems recommends verifying the
following points on the turbocharger:
Position of the turbine and compressor casings to the bearing casing
Shifting of the bearing casing in relation to the bracket
Cracks in casings
If during external inspection anomalies are found or if a particularly strong
deflagration event has taken place, it is also recommended to check the
bearings of the turbochargers before the next start. This inspection and
evaluation must be carried out by an ABB Turbocharging Service Station.
