Turbine cleaning during operation

5.3

The combustion of fuels such as heavy fuel oil (HFO) in diesel engines

produces contamination of the turbocharger's turbine components. In

combination with a high exhaust gas temperature, poor quality fuel can

lead to particularly hard deposits on the nozzle ring and especially on the

gas outlet flange.

ABB Turbo Systems recommends using fuels with a low ash, sulphur, so-

dium and vanadium content.

Consequences of contamination:

€

Poor turbine efficiency

€

elevated exhaust gas temperatures

€

higher charging and ignition pressures as turbocharger speed rises

€

lower engine performance.

€

After stopping the engine, the rotor can become stuck in contamination

deposits.

Experience with turbocharger operation shows that the intervals between

overhauls can be extended if cleaning while in operation is carried out pe-

riodically. Wet cleaning the turbine, as described below, should be used

for 4-stroke applications when there are heavy deposits from, for example,

HFO.

Under no circumstances is periodic cleaning of the turbine during opera-

tion a substitute for the service work carried out when the turbocharger is

completely dismantled and cleaned mechanically.

Turbines which are very heavily contaminated cannot be cleaned this way

any longer. In this case, the contaminated components must be mechani-

cally cleaned by an ABB Turbocharging Service Station.

NOTICE

Regular cleaning
Regular turbine cleaning during operation prevents or delays excessive

build-up of contamination.

Cleaning intervals

The interval between periodic cleaning is very dependent on the operating

conditions. In general, cleaning should be carried out every 50 to 200 op-

erating hours.
