Steam Heating Boilers Operating Pressure Settings Residential steam heating systems are almost always designed to operate at very low pressures, typically around 0.2 psi to a maximum of 0.5 psi - that' s 1/2 of one psi. Click to enlarge and you can see the actual pressure settings on the steam boiler control shown at left.

4 things to look out for in steam boiler pressure controls

Sep 28, 2016 · The boiler will cycle between 1 and 3 lb. of pressure. If the boiler uses a firing rate or modulating control, that changes the strategy a bit. I would set the operating control slightly higher, to operate between 2 and 4 psi and the firing rate or modulating control to operate between 1 and 3 psi.

How to control the working pressure of a boiler - Quora

Jul 25, 2018 · Pressure in a boiler is controlled by the use of pressure switches. These switched are designed to turn on the system when the pressure is too low, and turns off the boiler when it reaches the desired pressure. If your pressure is too high or won’t stabilise, you can try the following: Check that the pressure relief valve is tightly closed.

      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.

The HP boiler worked at approx 850 psi (5.86 MPa), and the low-pressure boiler at 200 to 250 psi (1.38 to 1.72 MPa). The UHP and HP boilers were of a water tube design, while the LP boiler was a fire tube boiler typical for steam locomotives. The LP cylinders were driven with a mixture of the HP cylinder exhaust and the LP boiler output.

Condensate from steam traps should always be returned to the TOP of condensate lines; the maximum height of rise above the steam trap to the condensate line is a function of steam pressure and the type of trap. A general rule of thumb is that 1 psi of steam will raise water about 2 feet.

Chapter 9 Boilers - NavyBMR

● Superheated steam is steam at a temperature higher than the saturation temperature corresponding to pressure. For example, a boiler may operate at 415 psig (pounds per square inch gauge). The corresponding saturation temperature for this pressure is 483°F, and this will be the temperature of the water in the boiler and the steam in the drum.

Although the definitions are somewhat flexible, it can be said that older steam generators were commonly termed boilers and worked at low to medium pressure (7–2,000 kPa or 1–290 psi) but, at pressures above this, it is more usual to speak of a steam generator. A boiler or steam generator is used wherever a source of steam is required.
