What is steam header in boiler?
What is steam header in boiler?
A steam header is the main steam supply pipeline, its function is to deliver steam in as high level of quality (dryness) as possible to the general areas where steam is needed. There are other headers called condensate headers that collect the condensed steam of users and returns it to the boiler feedwater system.
What is a drop heading?
A “dropped header” is a header that is installed below the roof or floor framing with a short wall (knee wall) between the header and the top plate.
How do I lower my boiler steam?
To reduce boiler losses and use less fuel to achieve the production rate you need, review these tips:
- Improve Your Boiler’s Combustion Efficiency (PDF 238 KB)
- Install an Automatic Blowdown Control System (PDF 212 KB)
- Insulate Steam Distribution and Condensate Return Lines (PDF 162 KB)
How does a steam header work?
A header transfers a heat transfer medium (water, steam, oil, etc.), typically via pipe(s), between (one or more) boilers and (one or more) points where the heat is required. A header can connect a single boiler to a single point where heat is needed.
How does a low loss header work?
A low loss header usually has a drain at the bottom of it. Hot water passes through the header at a lower pressure than it would pass through the rest of the system. This reduction in pressure and speed allows time for any dirt and debris in the system to sink to the bottom of the header.
What is header and footer?
A header is text that is placed at the top of a page, while a footer is placed at the bottom, or foot, of a page. Typically these areas are used for inserting document information, such as the name of the document, the chapter heading, page numbers, creation date and the like.
How do I reduce the blowdown on my boiler?
There are three ways to minimize boiler blowdown that will save water for your boiler plant. Automate Surface Blowdown • Proper Pre-treatment • Condensate Recovery Automating Surface Blowdown Automating the surface blowdown allows for the highest TDS (total dissolved solids) portion of the boiler water to be purged.
Why bottom blowdown is carried out?
Boiler blow down is done to remove carbon deposits and other impurities from the boiler. Blow down of the boiler is done to remove two types of impurities – scum and bottom deposits. This means that blow down is done either for scum or for bottom blow down.
What is the best way to get one-pipe steamed?
Balancing One-Pipe Steam Systems
- First, vent the mains quickly.
- Install a “Y” strainer before the main vent.
- Vent the radiators based on their size, not on their location within the building.
- Use two vents on oversized radiators.
- Insulate all the steam lines.
- Clean the system (and a dozen times, if necessary).
What type of pipe is used for steam boiler?
Pipes for steam systems are commonly manufactured from carbon steel ASTM A106. The same material may be used for condensate lines, although copper tubing is preferred in some industries.
What is the purpose of a drop header on a boiler?
The drop header (s) piping is sized to match the two top tappings in the steam chest which lets the boiler make more dry steam at a faster rate through the twin steam chest tappings and also making the boiler more efficient in the process in making dry steam using a common condensate drain from the drop headers back to the boilers water level.
How high should the steam header be above the boiler?
I think the bottom of the steam header should be a minimum of 24 inches above the top of the boiler jacket, and more than that, if possible. The higher the header, the drier the steam will be. Pros who do steam know this.
How do you use drop header piping?
Many of them use a Dead Man trick called a drop header. This is where you bring your risers to a very high point, and then turn with your elbows first over and then down before entering your header from the top. You can learn more about drop-header piping HERE.
Is it normal for boiler water to fill up the header?
Within a few minutes, boiler water has completely filled the two risers to the header and is spilling over into the header. People stare in amazement. The person running the show explains that this is normal.
