POWER GENERATION SYSTEM HAVING COMPRESSOR CREATING EXCESS AIR FLOW AND STORAGE VESSEL FOR AUGMENTING EXCESS AIR FLOW

摘要

PROBLEM TO BE SOLVED: To provide a method for employing an excess air flow to improve output of a power generation system.SOLUTION: A power generation system includes a first gas turbine system 102, including a first turbine component 104 and a first combustor 108 to which air from the first turbine component and fuel are supplied, the first combustor arranged to supply hot combustion gases to the first turbine component, and the first turbine component having a flow capacity greater than an intake capacity of the first combustor and/or the first turbine component, creating an excess air flow 200. A second gas turbine system 140 includes similar components to the first gas turbine system except not having an excess capacity in its compressor. A control valve system 202 controls a flow of the excess air flow from the first gas turbine system to the second gas turbine system. A storage vessel 252 is coupled to an excess air flow path 250 for augmenting the excess air flow with additional air during a peak demand period.SELECTED DRAWING: Figure 1
