Going further with super-efficient coated nozzle rings

super-efficient coated nozzle rings

Powerful and Efficient

“With the upgrade to 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..”

EGE Haina

The task

Nozzle rings play a crucial role in turbochargers by converting exhaust gases into kinetic energy to enable stronger combustion. But they need regular cleaning to perform efficiently. Washing can also mean 60 hours of reduced load each year. For a fleet of 15 vessels, for example, that could mean as much as $3,150,00 lost per year due to downtime. 

How we went further

Our superior nozzle ring coating is designed to maintain an optimal flow of exhaust gases for longer. Reducing turbo washing from around 60 times a year to just 10 slashes downtime and increases efficiency and productivity.  

Results

Our coated nozzle rings are delivering major cost savings across marine and stationary applications. Based on a typical 50 hours of cleaning downtime saved every year, a dredger with a 10,000 kW engine capacity can create $175,000 in additional revenue. By the same measure, a power station working with 17,000 kW engine capacity can generate $374,000 in extra energy sales.

Going further for EDF PEI

We helped EDF PEI to be the first power generator to trial Tekomar XPERT (now known as Tekomar for power plants). The year-long trial covered a total of 43 engines with a combined output of 750 MW.
