Condenser cooling water: A source of water external to a boiler's feed system is passed through the steam leaving the turbine in order to cool and condense the steam. This reduces the steam's exit pressure and recaptures its heat, which is then used to preheat fluid entering the boiler, thereby increasing the plant's thermodynamic efficiency.

Jun 21, 2012 · The bed of solid particles exhibits the properties of a boiling liquid and assumes the appearance of a fluid – "bubbling fluidized bed". 19. At higher velocities, bubbles disappear, and particles areblown out of the bed. Therefore, some amounts of particleshave to be recirculated to maintain a stable system –"circulating fluidised bed".
