Mar 07, 2015 · VANITA THAKKAR - BIT 17 NOZZLES A NOZZLE is a device, a DUCT of smoothly varying c/s area, that increases the velocity of a fluid at the expense of pressure. The chief use of nozzle is to produce a jet of steam (or gas) of high velocity to produce thrust for the propulsion of rocket motors and jet engines and to drive steam or gas turbines. A DIFFUSER is a device that increases the pressure of a fluid by slowing it down. Diffusers are used in compressors, combustion chambers etc.
Now steam pass through the nozzle or a set of nozzles where it is expanded from boiler pressure to the condenser pressure. Due to decreasing the steam pressure, its velocity becomes very high. This high-velocity steam first enters the first ring of moving blades where some portion of velocity is absorbed.
