The document describes a simple steam vapor power cycle. It consists of four main processes: 1) Water is pumped and pressurized in a boiler where it is heated and vaporized into high-pressure steam. 2) The high-pressure steam expands through a turbine, producing work and lowering in temperature and pressure. 3) The low-pressure steam is then condensed into water again in a condenser, releasing heat to the surroundings. 4) The water is pumped back to repeat the cycle. This vapor power cycle converts heat from fuel combustion into work.
