Abstract
A hybrid steam generating system and method in which fluid is passed through the waterwall tubes of a furnace to transfer heat from the furnace to the fluid to convert at least a portion of the fluid to steam. Under certain operating conditions, the heated fluid is passed from the furnace to a separator for separating the steam from the heated fluid and the separated heated fluid is passed from the separator back to the furnace. The steam from the separator is passed to a steam utilization unit, and, under certain operating conditions, the heated fluid is passed from the furnace directly to the steam utilization unit.
