Tips for a Successful Steam Boiler Replacement | U.S

Steam should always flow in the same direction in a header. This means there should never be a system riser between two boiler risers. All system risers should be piped after all boiler risers. Each system riser should be independent. Many system mains are piped together with one tee utilizing one steam riser.

Often the deaerator is a combination of two vessels; one vessel for removal of oxygen and non-condensable gases (scrubbing section), and a second vessel for storing hot feedwater (storage section). It is this 2 vessel design that provides superior results and efficiency as compared to simply having one steam heated "feedwater tank".
