A Rankine cycle with two steam turbines and a single open feedwater heater. A feedwater heater is a power plant component used to preheat water delivered to a steam generating boiler . [1] [2] [3] Preheating the feedwater reduces the irreversibilities involved in steam generation and therefore improves the thermodynamic efficiency of the system. [4]

Combined cycle technology allows a power plant to generate 50 percent more electricity from its fuel than it could with a singlecycle power system. Here's how it works: In a twoonone combined cycle system, two combustion turbine generators work in conjunction with two heatrecovery steam generators and a steam turbine generator.

Jun 08, 2018· This Innovative Technology Harvests Water from Cooling Towers. Just as in other industrial settings, cooling towers are an inherent part of the power plant's steam cycle. As the reactor heats ultrapure water to create steam to spin a turbine and generate electricity, a cloud forms and rises from the cooling towers, akin to the plume of "steam" that wafts from the brim of a hot cup of coffee.
