Refrigerant cooled main steam condenser binary cycle

This invention reduces the fuel consumption of the modern day power plant by lowering the main steam condenser operating pressure. The main steam condenser is a heat exchanger located in the power plant steam system for condensing steam. The main steam enters the main steam condenser, flowing around the tubes with the coolant flowing thru the tubes, condensing the steam. This invention replaces the present condenser once thru cooling water system with a refrigerant cooling system. The much lower normal temperature and greater high heat absorption rate of the refrigerant, lowers the main steam condenser operating pressure much below that of the present cooling water system. The lower condenser pressure increases steam flow, extracting more energy from the steam, increasing the plant-operating efficiency. This invention combines the conventional steam cycle with the conventional refrigeration cycle. The refrigerant compressor is driven by the main steam turbine which creates the binary cycle.
