      Jun 24, 2014 · The charts show that at 0-psig pressure, the steam will be moving along nicely at 30.44 feet per second. Raise the pressure to 5-psig and the steam slows to 22.5 feet per second. Bring the pressure up to 10-psig pressure and the steam moves at just 18 feet per second. You know why this happens? Because both the load and the pipe size are fixed.

      This lower pressure operation, combined with the shorter distance between the water/steam interface and the steam outlet pipe, further increase entrainment. Older boilers, while much larger, have a larger steam space which can tolerate greater changes in steam demand without severe changes in steam pressure or water level.

      Calculation of Extra BTUs needed to increase steam psi

      There is a notion that the boiler "has to work harder" to raise the steam pressure higher, so it must be using (wasting) more energy. As Cliff pointed out, the energy content per lb of steam is higher, but other than the standby loss potential, there's no impact on fuel to steam effiency per se.

      How to Fix Rising Boiler Pressure | DoItYourself

      Too much water in the expansion tank and too little air may also cause pressure to rise frequently. If the bottom of the tank does not feel hotter than the top, it indicates an excessive amount of water. You need to drain this water from the tank. To do so, first turn the boiler off. Then close the water shutoff valve and allow the system to cool.

      Jan 14, 2017 · At atmospheric pressure, water boils at 212 degrees F. In a pressurized steam system, that temperature is higher, as thermodynamic laws require. Increase pressure, increase boiling (vaporizing) temperature. So the liquid water in the lower portion of the boiler is above 212 degrees when steam is being produced.

      A high-pressure steam locomotive is a steam locomotive with a boiler that operates at pressures well above what would be considered normal. In the later years of steam, boiler pressures were typically 200 to 250 psi (1.38 to 1.72 MPa).High-pressure locomotives can be considered to start at 350 psi (2.41 MPa), when special construction techniques become necessary, but some had boilers that
