Steam Boiler Drop Header

Steam Headers and Off Takes | Spirax Sarco

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.

The resulting water steam mixture is then carried ahead through the same tubes to a steam drum. Steam is separated from hot water in the steam drum and sent to the steam superheater, where it is further heated and then sent to a steam header for distribution to the steam users.

Just want to show how a V9 steam boiler should be piped

Its called a drop header. The water in the boiler likes to follow the steam out. The extra turns acts as a steam separator and the water can drain back into the boiler through the equalizer. Water in the mains can cause water hammer and inefficient operation. Keeping the water in the boiler so the system heats faster makes everything work better.

Steam Header - Boiler Steam Header, Steam Distribution Header

Steam Headers and Off-takes Shell boilers are made for capacities up to around 27000 kg/h of steam. When loads in excess of this are required, two or more boilers are connected in parallel, with an installation of four or more boilers not being uncommon. The design of the interconnecting steam header is highly important.

Apr 30, 2013 · 0.50. An industrial steam distribution system with multiple headers, turbines, boilers, and reducing valves is managed with header control strategies that mitigate upsets, increase power generation, and reduce clean condensate makeup. Effective use of override, anti-windup, and TG governor interface strategies insure header stability.

Steam Pressure Reduction: Opportunities and Issues

A List of Boiler and Steam System Losses It is useful to summarize the typical causes of boiler and steam system losses. Most of these losses vary with steam pressure (and temperature) and can potentially be reduced by lowering the steam pressure at Pa = the absolute pressure drop across the orifice in pounds per square inch absolute (psia

3. STEAM SYSTEM

As steam condenses in a process, flow is induced in the supply pipe. Condensate has a very small volume compared to the steam, and this causes a pressure drop, which causes the steam to flow through the pipes. The steam generated in the boiler must be conveyed through pipework to the point where its heat energy is required.

Hartford Loop - Mass Engineers, Steam Engineering, Steam

A Hartford Loop is an arrangement of piping between a steam boiler's header and its gravity-return piping. The end of the header drops vertically below the boiler's waterline and connects into the bottom of the boiler. We call this pipe the "equalizer" because it balances the pressure between the boiler's steam outlet and condensate-return inlet.

Boiler Steam Headers | Steam header | Tpp Boilers Pvt. Ltd.

Headers form an important part of all types of boilers. Steam from the generating tubes is collected in headers which are therefore always under pressure. This pressure may vary from 300 psi to 2000 psi. Since headers are always under pressure, the utmost care is taken by us while fabricating them.

Drop header on residential steam boilers | Plumbing Zone

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

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 …

In that case, the header size is based on limiting the frictional pressure drop and /or noise, vibration and wet steam erosion/corrosion.

The steam header must be large enough to virtually eliminate pressure drop between the boiler and the beginning of the circuit.
