What is the purpose of the Hartford loop in a steam boiler?
What is the purpose of the Hartford loop in a steam boiler?
The Hartford loop is needed to prevent steam pressure in the condensate return line from forcing the liquid condensate (water) out of the boiler and back into the return piping system – something that could be a serious problem resulting in boiler water loss and boiler damage or destruction.
What is a steam loop?
Definition of steam loop : an arrangement of pipes by which water of condensation can be returned to the boiler without a pump or injector as a result of condensation of boiler steam in a loop of two vertical pipes connected by a horizontal one.
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 is a Hartford loop in plumbing?
Simply speaking, a Hartford Loop is a configuration of interconnected pipes associated with the gravity condensate return line on a steam boiler, and the point at which that condensation is re-introduced back into the boiler. It exists between the header of the boiler and the gravity return.
What is a Hartford loop?
What Is a Hartford Loop? Simply speaking, a Hartford Loop is a configuration of interconnected pipes associated with the gravity condensate return line on a steam boiler, and the point at which that condensation is re-introduced back into the boiler. It exists between the header of the boiler and the gravity return.
How hot can steam get under pressure?
212°F
When water is heated at atmospheric pressure, its temperature rises until it reaches 212°F (100°C), the highest temperature at which water can exist at this pressure. Additional heat does not raise the temperature, but converts the water to steam.
Where should an air vent be installed on a one pipe steam heating system?
The radiator’s air valve, or radiator air vent or steam valve as it is sometimes called, is used only in one-pipe steam boiler systems. It is usually located at the end of the radiator opposite the supply pipe, about halfway up or higher towards the top.
How hot is 50lb steam?
For example, saturated steam at 50 PSIG has a temperature of 298°F.
What is a Hartford loop on a steam boiler?
Categories: 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.
What do you need to know about a Hartford loop?
What you should know about the Hartford Loop. 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.
What is the configuration of a Hartford loop piping system?
This configuration was Figure is a schematic of a two-pipe system showing the. Hartford Loop piping arrangement and wet return are required wiring diagram. Piping system must be installed as shown, using minimum pipe sizes shown. Jun 24, A Hartford Loop is an arrangement of piping between a steam boiler’s header and its gravity-return piping.
Do I need A Hartford loop with my return pump?
If you’re using a condensate return pump, you really don’t need the Hartford Loop. As soon as you add that condensate- or boiler-feed pump to a steam system, you open the returns to atmosphere. At that point, the equalizer stops being an equalizer, and becomes just a drip line for the header.
