Steam Headers and Off Takes | Spirax Sarco

Jun 24, 2014 · The drop header keeps water from getting into the system, and allows for more expansion and contraction of boiler sections. This results in "dry" steam being fed to the system, which is steam at its most potent. Dave replies: Wet steam does not do much except cause water hammer. The best results are accomplished by "drying" the steam at the header (by increasing the steams "travel" distance at the boiler).

steamheating - Header piping

Steam exits the boiler through piping referred to as the steam header. The header also serves as a reservoir that feeds steam to the individual heating circuits. The steam header must be large enough to virtually eliminate pressure drop between the boiler and the beginning of the circuit.

Ian Sutton, in Plant Design and Operations (Second Edition), 2017. Steam Tracing. Steam tracing consists of small bore piping connected to the steam header and that is wrapped around the piping that it is protecting. The steam tubing can be connected to the pipe either with straps or by special heat-conducting cement. The steam condenses as it flows along and is collected in a steam trap.

Steam Header - Boiler Steam Header, Steam Distribution Header

Jun 13, 2011 · They are a very good thing for a steam boiler, especially if the existing supply/feed is close to the recommended height above the water line in the boiler. Your supplies off the top of the boiler can go up much higher to the ceiling and back down to the header which has the equalizer and feed the system off the header. Keeps the steam drier.

Drop header on residential steam boilers | Plumbing Zone

The main observation is that this design of distribution header does not allow the boilers to share the load equally. The aim should be that the pressure drops between each boiler outlet and the header off-take to the plant should be within 0.1 bar. This will minimise carryover and help to prevent overload and lockout of boilers.

Section 23 52 39 - FIRE-TUBE BOILERS

Steam lines should ideally be arranged to fall in the direction of flow, at not less than 100 mm per 10 m of pipe (1:100).This slope will ensure that gravity (and the flow of steam), will assist in moving the condensate towards drain points so that the condensate may be safely and effectively removed (see Fig. 15.4).Any steam lines rising in the direction of flow should slope at not less than

this header is first reduced in pressure to 10 psi and then cooled down with water injection as close as possible to the saturation temperature for 10 psi steam of 240°F. Your lumber quality will improve immensely, your boiler will be loafing, your fuel bill will drop dramatically. As I said at the beginning, steam is an amazing substance.

Weil Mclain SGO-8 Gas Fired Steam Boiler With A Mega Drop

I'd like to talk about header piping on steam boilers. In older boilers, the boilers were designed to have a very large open space inside, which allowed the water to boil and bubble, but not "wet" the top of the boiler, inside. This allowed for space inside the boiler for the steam to form and let the water drop …

Sep 01, 2006 · Steam inlets to "horizontal" headers may be at one end or at mid length, but with vertical headers the steam inlet is preferably near the top. Coils with a center inlet connection make it more difficult to ensure that air is pushed from the top tubes; the steam tends to short-circuit past these tubes to the condensate header.
