Just want to show how a V9 steam boiler should be

Its called a drop header. The water in the boiler likes to follow the steam out. The extra turns acts as a steam separator and the water can drain back into the boiler through the equalizer. Water in the mains can cause water hammer and inefficient operation. Keeping the water in the boiler so the system heats faster makes everything work better.

3. STEAM SYSTEM

2017-9-8 · As steam condenses in a process, flow is induced in the supply pipe. Condensate has a very small volume compared to the steam, and this causes a pressure drop, which causes the steam to flow through the pipes. The steam generated in the boiler must be conveyed through pipework to the point where its heat energy is required.
