Use of ABB turbochargers on gas engines
2.8
ABB turbochargers can withstand a deflagration with a transient pressure
increase of 12 bar. A maximum of 11 bar has been measured during
deflagration trials on engines with flame traps. The practical operating
experience of well-known manufacturers of gas engines reinforces this
value. Damage to ABB turbochargers during deflagration events has not
been determined in the past.
ABB Turbo Systems recommends that, following a deflagration event, the
turbocharger undergo a visual inspection. Items to check during this
inspection are the position of the turbine casing, of the compressor casing
to the bearing casing as well as a shifting of the bearing casing in relation
to the bracket. A crack inspection of the casing is also recommended. The
nearest ABB Turbocharging Service Station should be commissioned with
this inspection and assessment.
