However a residential steam boiler pressure is so modest (0.2 psi to 0.5 psi) that the temperature increase above 212 F will be no more than about 220 F. A commercial boiler system heating a high-rise building may be operating at much higher pressures, perhaps 20 to 40 psi in order to be able to force steam to 20 or 40 floors of building height.

The boiler pressure is 12.5 MPa and temperature is 510°C. The condenser pressure is 50.8 mmHg and temperature is 38.4°C. The regenerator pressure is 132 kPa. Habib et al. (1995) indicated that for maximum efficiency of a single reheat cycle, the reheat pressure should be approximately 19% of the boiler …

To generate steam, you have to reach at least 100C, or 212 degrees Fahrenheit. However, the more pressure that exists in the boiler, the higher the temperature can be. So you could have a boiler with a water temp of 450 degrees F. Someone who knows more about steam than I do can tell you what pressure it would be at in this condition.

The inlet temperature of the turbine (or the outlet temperature of the boiler) is varied between 500 C and 700 C in steps of 20 C. Also, the inlet pressure of the turbine (or the outlet temperature of the boiler) is varied between 8 MPa and 10 MPa in steps of 200 kPa.

The main parameters that affect a steam boiler's efficiency are boiler load, combustion air, stack gas temperature, radiant heat loss, and acid dew point. In this article, natural gas fired conventional steam boilers are evaluated and potential savings are determined in the power plant of Tüpraş İzmir refinery.
