Maximizing your uptime.

Superior nozzle ring coating.

Optimal flow of exhaust gases through the nozzle ring.

Crucial for overall turbocharging and application efficiency.

Used to convert exhaust gases into kinetic energy in turbochargers, nozzle rings are crucial to energy efficiency. When optimized, they can increase air intake into the engine cylinders, providing better and stronger combustion, which in turn increases output and efficiency.

The Coated Nozzle Ring.

Small components, big impact.

Used to convert exhaust gases into kinetic energy in turbochargers, nozzle rings are crucial to energy efficiency. When optimized, they can increase air intake into the engine cylinders, providing better and stronger combustion, which in turn increases output and efficiency.

Thus, the optimal flow of exhaust gases through the nozzle ring is crucial for the overall turbocharging and application efficiency.

Dealing with dirty nozzle rings.

With an average engine runtime of 6000 hours per year, turbo washing would generate 60 hours of reduced load per year.

The true costs of dirty nozzle rings.

Experience from both marine and stationary applications show operators suffer huge financial losses due to repeated turbine cleaning. A large operator with a fleet comprising 15 vessels would lose more than $3,150,000 per year due to maintenance downtime.

Extension of cleaning interval up to 6 times with coated nozzle rings.

For application operators this would mean a reduction in cleaning cycles from 60 times per year to just 10 times per year, maximizing uptime.

EGE Haina earns an additional $3.3m with extended cleaning interval.

“With the upgrade to ABB’s coated nozzle rings we have been able to extend our intervals between cleaning from 50 to 300 running hours. This means we regain nearly 1,900MWh of otherwise lost power on each engine annually with even less maintenance effort.”
