Abstract
A boiler includes a steam drum, an intermediate drum, and a lower drum. Each drum is divided into a clean section and a concentrated section. A channel that is fluidly connected to the clean section also runs down one side of the concentrated section in the intermediate drum and the lower drum. The presence of the channels permits low-quality feedwater tubes and high-quality feedwater tubes to be arranged in parallel rows next to each other.
