T- VTR 4 series turbocharger nozzle ring (guide vane) belongs to one part of T- ABB / T- VTR series exhaust gas turbocharger. The T- ABB / T- VTR series marine turbocharger is created for two-stroke, low-speed and four-stroke, medium-speed heavy-duty diesel engines. The engine power output is from 700 kW to 18,500 kW per turbocharger. T- VTR series turbocharger has been widely applied to marine propulsion engines (esp. at part load), stationary power plants and units burning heavy oil and in continuous operation. The advantages are as following:

The engine exhaust gas expands through a nozzle ring where the pressure energy of the gas is converted to kinetic energy. This high velocity gas is directed onto the turbine blades where it drives the turbine wheel, and thus the compressor at high speeds (10 -15000 rpm). The exhaust gas then passes through the outlet casing to the exhaust uptakes.
The nozzle ring need to bear the extremely high temperature and high pressure, so it's very crucial for its material selection.
The turbocharger nozzle ring is usually fabricated from a creep resistant chromium nickel alloy, heat resisting moly-chrome nickel steel or a nimonic alloy.
The marine turbocharger, also known as exhaust gas turbocharger, is the main equipment in the diesel engine boosting system. It consists of a single-stage exhaust gas turbine and a centrifugal compressor. They are mounted on the same shaft to form the moving part of the marine turbocharger/exhaust gas turbocharger - the rotor. The function of the marine turbocharger/exhaust gas turbocharger is to use the diesel exhaust energy to drive the turbine to drive the compressor on the coaxial to increase the air pressure into the cylinder, so that the diesel engine power is greatly improved. The exhaust turbocharger approximately doubles the power of the diesel engine, but its weight is only increased 10%.
