Getting the Most Out of Modern Steam Boilers | Liming

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.

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.

Guide to Steam Systems Part 2: Steam Distribution

5. If the boiler is severely oversized, the steam flow in the mains will cause too much pressure drop. The water in the returns will rise and water hammer can occur. E. COUNTERFLOW SYSTEMS 1. Basic system piping and operation a) Condensate must flow against the flow of steam b) The boiler header must enter the top of the main on counterflow

Drop header or not — Heating Help: The Wall

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.

How NOT to Design a Steam System - The C&S Companies

The reheating steam is supplied to the upper header of each tube element and condenses on the inside of the tube. The condensate is piped from the bottom header and passed to the feed train. The heating steam supply to the elements through which the separator exhaust steam first passes, is obtained from a tapping on the HP cylinder.


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 …

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).
