ultra-high pressure boiler outlet steam pressure

High-pressure steam locomotive - Wikipedia

Hence, H at inlet and outlet is same. With reduced pressure to 3 bar g, Hf = 144.74 kcal/kg and Hfg = 510.29 Kcal/kg. Total heat i.e. H remains constant, however the dryness fraction increases to 0.97. This example illustrates that a reduction in steam pressure enhances the quality of steam. It is equally important to select correct pressures.

High Pressure Steam Boilers | Lathrop Trotter | Lathrop

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.

Relation Between Steam Turbine Inlet pressure and Steam

The sealed ultra-high-pressure circuit ran at between 1,200 and 1,600 psi (8.27 and 11.03 MPa), depending on the rate of firing. 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).

Characteristics of a High Pressure Boiler Power of Steam: Water expands 1600 times to form steam, which can carry large amounts of heat. This makes water an economical and ideal raw material for generating heat and power. High pressure boilers heat water to create steam at over 15 psi and have water pressure over 160 psig.
