Abstract
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 control station is provided which includes one or more relatively small bore tubes, a first conduit having control means disposed therein, and a second conduit, through which fluid passes before it is passed to a plurality of separators in the main flow path which receives the fluid and separates same 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 heat recovery or condenser, respectively. A method of starting up a vapor generating system in a power plant.
