The boiler is firing and making steam pressure. The pressure is rising, and the boiler is in low fire due to low load. The operator control will shut down the boiler to prevent too much steam pressure from building up. However, the operator control is not the same as the boiler steam pressure setpoint. These are commonly confused.

Nov 21, 2010 · ALL residential steam boilers have a Maximum Allowable Working Pressure (MAWP) of 15 psi. Either you read the gauge incorrectly or the gauge is nothing but a paperweight attached to the boiler. Most residential steam heat systems work well with less than 2 psi and some work well with 1/2 psior at least as well as a residential steam system can.

Dec 30, 2019 · Pressure changes of a few psi one way or the other can be brought about by atmospheric conditions. Most boilers are safe up to around 30 psi, at which point seals can begin to fail. Modern boilers arent nearly as dangerous as early steam engines, but you can still damage them and require costly repairs. Provided your boiler
Click to enlarge and you can see the actual pressure settings on the steam boiler control shown at left. 0.2 psi = 0.014 Bar or about 1378 Pascal of pressure - typical low-end of residential steam boiler pressure settings. 0.5 psi = 0.034 Bar or about 3447 Pascal of
Mar 17, 2015 · Steam, Boiler, and Blowdown Pressure are the same. Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. Blowdown Rate is the % of incoming feedwater mass flow rate that leaves the boiler as a saturated liquid at boiler pressure.
