Reheat steam temperature control in a circulating fluidized bed steam generator

摘要

A method of controlling the reheat steam temperature in a circulating fluidized bed combustion system wherein the circulating solids are cooled in a heat recovery fluid bed system containing reheat heat exchange surface. The rate of heat transfer and thus the reheat steam temperature are controlled by adjusting the flow rate of fluidizing air to the portion of the heat recovery fluid bed system containing the reheat surface.
