Turbine side washing (TSW) and coating turbine blades safeguard turbocharger efficiency and protect your turbocharger.

What causes blade damage and loss of efficiency?

  • Lubricating oils, when used together with heavy fuel oil in dual-fuel engines running in gas mode, create contamination.
  • This contamination can appear as deposits on the turbine-side components, such as TPL-A/C turbine blades.
  • These deposits impair turbocharger efficiency and performance, cause blade excitation and can, ultimately, result in turbocharger breakdown.
  • Efficiency is impacted particularly when contamination buildup wears the turbine blade tip and increases tip clearance.

What can we do about it?

  • Performing TSW while the engine is running removes residues.
  • TSW only needs water.
  • Coating the tips of six turbine blades (“Dragon’s Teeth”) lets them cut away any deposits in the diffuser and prevents wear on the standard teeth.
  • Coating the blades ensures tip clearance is maintained and the high efficiency of the ABB turbocharger is preserved.
  • Blade tip coatings also reduce thermal loading of the engine and eliminate costly repair or renewal of all the blades.

Blade cleaning and coating will increase the lifetime of your turbocharger make it run more efficiently!

If you want your dual-fuel engine to run smoothly
Perform TSW after ~ 150 h running time

By carefully following ABB guidelines, operators can perform turbine cleaning while the engine is in operation, thus minimizing downtime. Turbine cleaning is complex and, to provide innovative turbine cleaning systems, ABB Turbocharging invests in extensive development and testing.
