Koretsky, "Engineering and Chemical Thermodynamics", John Wiley & Sons, 2004) B_01tbl 2. Table 24[20] gives such properties of superheated steam for varying pressures as are necessary for use in ordinary engineering practice. Calculate the amount of steam at 300 (produced, and the required volumetric flow rate of the 400 (steam. Raise the degree of superheat of supplied steam as specified and maintain the The majority of the thermal energy in the steam (latent heat of vaporization) is trans-ferred when the steam condenses to water. The primary function of a steam generator is to generate steam under pressure, but modern steam generators are also required to do the following: i. H. MILWAUKEE VALVE HAMMONDVALVE Inches Absolute STEAM TEMPERATURE PRESSURE TABLE SATURATED STEAM TEMPERATURES Temperature Gauge Temperature Gauge Temperature Gauge Temperature Gauge The sum of the Heat of the Liquid (Column 4) and Latent Heat (Column 5) in Btu. An explanation of other means. Specific Heat of Superheated Steam—The specific heat of superheated steam at atmospheric pressure and near saturation point was determined by Regnault, in 1862, who gives it the value of 0.48. Total Heat of Steam (Column 6). The mixing input operates adiabatically. The sum of the Heat of the Liquid (Column 4) and Latent Heat (Column 5) in Btu. The following brieflydescribes a few of the major thermophysical attractions of steam to the engineer. (iv) Temperature and pressure in main steam and reheat steam. steam condensing rate is known. 0.075 645 3076.5 8.9625 300 8811.0 0.113 49 3076.2 8.7750 26 907. Superheated steam at 300 (and 1 atm is needed as a feed to a heat exchanger; to produce it, the turbine discharge stream is mixed with superheated steam available from a second source at 400 (and 1 atm. This heat quantity is different for every pressure/temperature combination, as shown in the steam table. B_04_cont2_tbl 12. B_04_cont3_tbl 13. In the application section of this Handbook, there are several references to the use of the steam table. Figure 3-2 shows graphically that what Total Heat of Steam (Column 6). steam. Steam at 213 degrees F is superheated by one degree F. Superheat is then any temperature of a gas above the boiling point for that liquid. B_04tbl 10. B_04_cont5_tbl 15. Finally, if further, heat is added to one kilogram of dry steam in the cylinder at the constant pressure, the temperature of steam will rise and there will be further increase in volume of steam as shown in fig. The thermophysical properties of steam change as its conditions of state change and it is relatively easy to generate steam across a wide range of states. 3-1 (e). The degree of super heat in super critical boiler is necessary to maintain the stability of steady state Consequently steam has a very wide range of applications. Ensure generation of exceptionally high-purity steam by eliminating all impurities from saturated steam. B_04_cont4_tbl 14. B_02_cont_tbl 7. The steam produced is known as superheated steam. Saturated Steam: PRESSURE Table 5. B_03tbl 8. B_02tbl 6. (v) Total load in MW. This same amount of heat is released when a pound of steam is condensed back into a pound of water. In steam heating applications, the most effi cient heat transfer occurs when high quality (100%) steam at saturation tempera-ture is condensed in the heat exchanger or process. Compressed Water and Superheated Steam (continued) 0.01 MPa (ts = 45.806 °C) 0.02 MPa (t s = 60.058 °C) 0.03 MPa (t s = 69.095 °C) v ρh s t, °C v h s t, °C v ρ h s 26 446. It is the total heat in steam … 17 Table 3. (vi) Limits of operation for above all One of the important parameter in above list is Over Heat Degree (OHDR) of Superheat in evaporator zone of boiler.
