It is recommended to size the steam lines based on the steam flow and velocity requirements. If a line is being consciously over sized, the benefits should be balanced against these daily losses. The steam carrying capacities (in kg/hr) for some of the typical line sizes is presented below. The acceptable velocity of steam flow is limited to 25m/s.
Steam boiler sizing dilemma. Ed59 Posts: 12 Member. April 2014 in Strictly Steam . It is 8 or 9 feet above the floor, so I'm hoping not too much wet steam gets up there). Maybe this counts as particularly "unusual" piping. (The mains are not well insulated now, but I'd plan to do that especially well if I got the smaller boiler)
These returns are above the boiler water line and have a combination of water, air, and steam at various times. The pipe sizing has to accommodate all three without backing condensate into a coil. Dry returns must be sized for pressure drop at the rated flow and provide sufficient room for water flow (condensate), air, and flash steam.
