Abstract
The present application provides a once-through evaporator system. The once-through evaporator system may include a number of enlarged once-through evaporator sections, a first superheater positioned immediately downstream of the enlarged once-through evaporator sections, a second superheater positioned downstream of the first superheater, and an attemperator positioned between the first superheater and the second superheater.
Claims20
A method, comprising:
- controlling, via at least one controller, a valve:
- to control a flow of a liquid into a once-through evaporator and to selectively vary an output between a steam and a first superheated steam, wherein the once-through evaporator is configured to selectively output only the steam and the first superheated steam;
- and
- receiving the steam or the first superheated steam from the once-through evaporator into at least one superheater fluidly coupled to the once-through evaporator, wherein the at least one superheater is configured to output a second superheated steam, wherein the steam or the first superheated steam flows directly from the once-through evaporator to the at least one superheater.
