Ratteau turbine

Another impulse turbine is the pressure eompound or Ratteau turbine. In this turbine the work is broken down into various stages. Eaeh stage eonsists of a nozzle and blade row where the kinetie energy of the jet is absorbed into the turbine rotor as useful work. The air that leaves the moving blades enters the next set of nozzles where the enthalpy deereases further, and the veloeity is inereased and then absorbed in an assoeiated row of moving blades. [Pg.345]

Figure 9-8 shows the Ratteau turbine. The total pressure and temperature remain unehanged in the nozzles, exeept for minor frietional losses. [Pg.346]
