A vapor generating system for use in a power plant having a steam turbine and a condenser connected in a series flow relationship, in which a vapor generating section receives a heat exchange fluid and passes the fluid in a heat exchange relation to a source of heat to raise the temperature and pressure of the fluid to predetermined values. The vapor generating section operates at substantially constant pressure during start-up and a pressure reducing station is provided for reducing the pressure of the fluid before it is passed to a plurality of separators in the main flow path for receiving the fluid and separating the fluid into a liquid and a vapor. The separators are connected to a vapor circuit and to a liquid circuit for passing the vapor and liquid to the turbine and condenser, respectively. A method of starting up a vapor generating system in a power plant.
A vapor generating system for use in a power plant having a steam turbine and a condenser connected in a series flow relationship, said system comprising a vapor generating section for receiving a heat exchange fluid and applying heat to said fluid, a superheating section for applying additional heat to said fluid, fluid flow circuitry directly connecting said vapor generating section to said superheating section, pressure reducing means connected directly in said fluid flow circuitry between said vapor generating section and said superheating section for receiving said heated fluid from said vapor generating section and reducing the pressure thereof, separation means connected directly in said fluid flow circuitry between said pressure reducing means and said superheating section for receiving said heated fluid at said reduced pressure and separating said fluid into a liquid and a vapor, said fluid flow circuitry passing all of the vapor from said separation means to said superheating section during start-up and full load conditions.
A method of generating vapor for use in a power plant having a steam turbine and a condenser connected in a series flow relationship, comprising the steps of passing said fluid through a vapor generating section to apply heat to said fluid, directly passing said fluid from said vapor generating section to a superheating section to apply additional heat to said fluid, reducing the pressure of said heated fluid as it passes from said vapor generating section to said superheating section, separating said fluid into a liquid and a vapor after said step of reducing and before the fluid is passed to said superheating section, all of the separated vapor being passed to said superheating section during start-up and full load conditions.
