A cfb steam generator with a superheater and a reheater

摘要

A method for exercising control over the final predefined superheat outlet steam temperature and for exercising control over the final predefined reheat outlet steam temperature from a circulating fluidized bed steam generator having a furnace volume embodying at least superheat surface, a multichambered backpass volume embodying at least superheat surface within one chamber of the multichambered backpass volume and at least reheat surface within another one of the multichambered backpass volume, a first circulatory fluid flow path operative as an evaporative steam loop, and a second circulatory fluid flow path operative as a superheat steam-reheat steam loop and including a saturated steam segment, a superheat steam segment, a reheat steam segment and an economizer segment.
