T- MAN Turbocharger Nozzle Ring / T- TCA88 Turbo Guide Vane For
Marine, Power And Industrial Engines
T- MAN / T- TCA series marine turbocharger features:
T- TCA88 turbocharger nozzle ring (also called guide
vane) belongs to one part of T- MAN / T- TCA series marine turbocharger with the features
as below:
- T- MAN / T- TCA series exhaust gas turbocharger is a axial-flow turbocharger
with wide application range of two-stroke and four-stroke
engines.
- For engine power output range from 2000 to 30000 kW per
turbocharger;
- Axial flow turbine inboard high performance plain bearing design;
- Whispering silencer with air filter;
- Low-noise, Easy maintenance compressor wheel due to it special fastening
method;
- Uncooled bearing casing;
- Easy access to thrust bearing;
- Integrated sealing air, oil pipe and venting systems;
- High efficient diffuser;
- Long-life and adjustable nozzle ring;
- High efficiency of turbine blades is designed to be possible to
omit the otherwise usual damping wire in the blade ring both for
2-stroke and 4-stroke engines;
- Suitable for heavy fuel, diesel oil, biofuel and gas operation;
- widely used in marine, power and industrial applications of
diesel-powered and gas-powered engines.

T- TCA88 turbocharger nozzle ring (turbo guide vane) functions:
- The turbocharger nozzle ring is in the where the energy in the
exhaust gas is converted into kinetic energy, so the nozzle ring
need to bear the extremely high temperature and high pressure.
- The turbocharger nozzle ring is usually fabricated from a creep
resistant chromium nickel alloy, heat resisting moly-chrome nickel
steel or a nimonic alloy which will withstand the high temperatures
and be resistant to corrosion.
- Furthermore, due to its function is to convert the exhaust gas into
kinetic energy, the precision processing of the nozzle ring is
highly demanded.
