Deflagration on gas engines

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. An ABB Turbocharging Service Station should be instructed to carry
out this inspection.
