Abstract
A combustion turbine power plant includes a modular compressor assembly structured to enclose multiple configurations of vanes and blades, a modular combustor assembly structured to be disengagably coupleable to a fuel source, a modular first turbine assembly structured to enclose multiple configurations of vanes and blades, a modular diffuser, a modular second turbine unit, a work unit, and a modular heat exchange system. A work unit shaft is structured to have two ends that are disengagably coupleable to the modular second turbine unit and the work unit. A compressor turbine shaft is structured to have two ends that are disengagably coupleable to the modular compressor assembly and the modular compressor turbine assembly.
