2.8 Deflagration on gas engines
ABB turbochargers can withstand a deflagration with a transient pres-
sure increase of 12bar.
ABB Turbocharging recommends that, following a deflagration event,
the turbocharger undergoes an inspection of the following points:
¡ 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 in-
spection and evaluation must be carried out by an ABB Turbocharging
Service Station.
