\"Dropped\" Header for Steam — Heating Help: The Wall

Maintain the mimimum 24" rise from the Water Level and then drop the header about 6". Going to larger diamter pipes is not a bad thing provided you carry that down to the equalizer connection. Here is a drawing of our V8 with 2 boiler risers and a dropped header. In this one we call for 2" boiler risers and a 3" common header. Hope this helps.

The importance of near-boiler piping in a steam system

The importance of near-boiler piping on a steam system Years ago, steam heating was a business of installing complete systems and not just a business of replacing boilers and fixing problems, as it is today.

Bourgeoning Brewery Cheers New Efficient Boiler System

To add efficiencies to the system, LaBar designed it to feature two five inch steam risers from the boiler into a six inch drop header to provide the dry steam. This design ensures the steam used in the process is extremely dry. “The dryer the steam, the more efficient the system,” said LaBar.

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.

steam main to the new unit. The use of the tables is best described by solving a typical problem: Assume a boiler operates at a steam pressure of 15 psig and is supplying a 300-ton steam absorption machine which requires a minimum operating pressure of 12 psig. There is a 2 psig pressure drop along the steam mains and the

Instantaneous Steam Production Boiler depressurization rate is a function of the boiler and steam system’s ability to create instantaneous steam. The amount of instantaneous steam a boiler system will produce is simply the amount of stored steam the boiler will release when the steam header …

Piping for Steam Distribution

Steam is widely used in most of the process industry as process heating media and in all power generation plants. Handling of steam is becoming very important. To study and understand the property of stem, condensate and it’s effect on the material of construction is again important while designing the piping system for steam distribution.


Where used, they should be preferably placed directly on the boiler nozzle. Where two or more boilers are on one line, in addition to the valve at the boiler, whether this be an automatic valve or a gate valve, there should be an additional gate valve on each boiler branch at the main steam header.

What is a Drop Header?

The best results are accomplished by "drying" the steam at the header (by increasing the steams "travel" distance at the boiler). That's usually tough to do in a low basement, so a drop header can give you the best of both worlds. Bob Young replies: As Dave pointed out, extra dry steam is a key result and it makes piping a proper header a snap ...

Effective Boiler-Level Control

Steam header. Multiple-boiler systems employ a steam manifold usually referred to as the main distribution header (Figure 1). Proper flow to and from a steam header is necessary for efficient warmup, good steam quality, and proper steam distribution. The design of a distribution header should allow boilers to share a load equally.

Water for the Boiler

With a boiler operating under constant load and within its design parameters, the amount of entrained moisture carried over with steam may be less than 2%. If load changes are rapid and of large magnitude, the pressure in the boiler can drop considerably, initiating extremely turbulent conditions as the contents of the boiler flash to steam.


An air cock is located in the uppermost steam space of a boiler, as shown in item 7 in figure 1-6. This design allows for air to enter and escape during filling and draining of the boiler. Before firing a cold boiler with no steam pressure, the air cock is opened to …

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 back down.
