Contaminants, present in the air or the fuel, are deposited on the blades of a compressor or turbine.

DISPLACEMENT COMPRESSOR

A type of compressor that depends on displacement of a volume of air by a piston moving in a cylinder.

VACUUM PUM

Low-pressure air compressor that takes suction from a region below atmospheric pressure (turbine condenser) and discharge into the atmosphere.

TURBO CHARGER

The blades of a turbine in the outlet exhaust flow of an engine are driven by the gases flowing over them. Compressor blades at the other end of the same axle are spun in the inlet flow, drawing large volumes of air into the cylinders. This enables faster combustion than naturally aspirated engines and increases power of the engine.

AXIAL FLOW COMPRESSOR

A compressor that uses rotor blades shaped like airfoils that give the air a high velocity and push it into subsequent stationary blade passages that convert the velocity energy into pressure. This process is repeated through several stages. The airflow movement is axial.

INTERCOOLED CYCLE

A gas turbine employing two compressors, the compressed air from the first compressor is cooled before being discharged into a second compressor.

DUCT

A passage for air or gas flow.

DEPOSIT GAGE

The general name for instruments used in air pollution studies for determining the amount of material deposited on a given area during a given time.

VOLUME OF AIR

The number of cubic feet of air per minute expressed at fan outlet conditions.

ACCELERATOR JET

The jet through which the fuel is injected into the incoming air in the carburetor with rapid demand for increased power output.

AIR-COOLED CONDENSER

A heat exchanger which uses a natural or forced flow of ambient air around the outside of a set of tubes to cool and condense a vapour contained inside the tubes.
