- Supply and return lines: Each heating coil is connected to the main steam line through a supply line, which delivers steam to the coil, and a return line, which carries the condensate (water formed when the steam cools down) back to the boiler for re-heating.
- Heating coils: The heating coils are the devices that transfer heat from the steam to the air or liquid being heated. They are typically made of copper or steel and are designed with fins or tubes to increase the surface area for heat transfer.
- Air vents and traps: To ensure efficient operation, the system is equipped with air vents to release any air trapped in the pipes and traps to remove condensate from the coils without losing steam. These components help maintain proper steam flow and prevent damage to the heating coils.
In a single-loop piping diagram for steam heating coils, the steam flows from the boiler through the main steam line to the supply lines of each heating coil. The steam gives up its heat to the air or liquid in the coils, and the resulting condensate flows back to the boiler through the return lines. This continuous loop ensures that the steam is effectively utilized and provides consistent heating to the building or space.
