Sudden boiler pressure drop when open steam - Page 2

erics wrote: My Anita responds almost exactly as yours in that the boiler pressure will surely drop the moment the steam valve is opened. HOWEVER, even with the steam valve fully open, the machine will recover to normal max boiler pressure (~1.17 bar) and the heating element goes out.

15 Tips to Peak Performance in Steam Heating Systems

Tip No. 2 Make sure main vents are installed and working properly. End of main vents have to be there to have even distribution of the steam along the main. Steam moves from the higher pressure in the boiler, to the lower pressure at the open air vent. The steam supply main is full of air at the start-up of each run cycle.

High pressure steam boilers in battery (two or more ) require two stop valves in series on each boiler as well as a check valve on each boiler. It is common procedure to use 1 stop valve and 1 non-return valve (which is a combination stop valve and check valve in one body) There is also supposed to be a manual drain valve between the two stop

Boiler and steam supply: In larger systems, consider installing an automatic valve in the steam supply line, arranged so that the valve stays closed until a reasonable pressure is attained in the boiler. The valve can then be set to gradually open, allowing flow, temperature and pressure in the distribution system to reach equilibrium slowly.

Steam is a gas and it will always look for a way out of the system. When it leaves the boiler, it heads toward the air vents. The bigger the air vent, the more inclined steam will be to head that way. If the system heats unevenly, install a good, high-capacity main vent near the end of the each main and watch the difference it makes.
