4.8 Cleaning the inlet valves and the inlet channel
Fig. 4.8.1 – 4.8.4
The blasting probe must be positioned
close to the surfaces being cleaned. The
cleaning phases should last no more than
2-3 seconds. Then the area being cleaned
should be blown out again with air.
Alternate between cleaning and blowing
out several times. Each time the blast-
ing probe must be moved to a different
position so that the entire coked area is
cleaned.
Fig. 4.8.5
After all cleaning positions have been
blasted once, the cleaning result must
be visually inspected. If the result is un-
satisfactory, the process must be repeat-
ed and/or the operating pressure of the
device increased.
Max. 8 bar!
Fig. 4.8.6
The inlet valves and the inlet channel
area should be bare and free of carbon-
isation.
When cleaning and blowing out, blast-
ing medium must not escape from the
suction adapter! If blasting medium is
escaping, the power of the suction unit
is not sufficient.
