Enhanced steam cycle utilizing a dual pressure recovery boiler with reheat

A dual pressure boiler and steam turbine system comprising:

• a top furnace for producing high pressure steam, a high pressure superheater fluidically connected to the top furnace for superheating the high pressure steam, and a high pressure steam turbine for receiving steam from the superheater and producing a flow of exhaust steam;
• economizer convection heating surface fluidically connected to provide heated feedwater to the top furnace;
• a bottom furnace comprising economizer fluidically connected to provide heated feedwater to the economizer convection heating surface;
• a feedwater pump for providing feedwater to the bottom furnace;
• a reheater for reheating the flow of exhaust steam from the high pressure steam turbine;
• and
• a low pressure steam turbine for receiving the reheated steam.

• a top furnace for producing high pressure steam, a high pressure superheater fluidically connected to the top furnace for superheating the high pressure steam, and a high pressure steam turbine for receiving steam from the superheater and producing a flow of exhaust steam;
• a bottom furnace comprising a low pressure natural circulation steam generating system for producing low pressure steam;
• a reheater for reheating the flow of exhaust steam from the high pressure steam turbine;
• a low pressure steam turbine for receiving the reheated steam;
• a second low pressure steam turbine for receiving the low pressure steam from the bottom furnace;
• and
• a condenser for receiving the exhaust steam from at least one of the low pressure steam turbine and the second low pressure steam turbine.
