The total specific enthalpy of the steam (or heat required to evaporate water to steam) at atmospheric pressure and 100 oC can be summarized as: = 2676 (kJ/kg) / 3600 (s/h) = 0.74 kWh/kg. Note: - You cannot use commas (,) as decimal points. At atmospheric pressure (0 bar g, absolute 1 bar ) water boils at 100 o C and 417.51 kJ of energy is required to heat 1 kg of water from 0 o C to evaporating temperature 100 o C. The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow: Pressure = 163.0 psig Temperature = 18.9 °C Example: 1.02 not 1,02.

Combustion Efficiency is the % of fuel energy that is directly added to the feedwater and not otherwise lost or used. are not considered. Privacy Policy. Vacuum steam is the general term used for saturated steam at temperatures below, Specific enthalpy - or Sensible Heat - is the quantity of heat in. Using the Steam Property Calculator, properties are determined using Inlet Pressure and the selected second parameter (Temperature, Specific Enthalpy, Specific Entropy, or Quality). Includes 53 different calculations. If you continue without changing your cookie settings, we assume that you consent to our use of cookies on this device. Saturated Steam Table: The Temperature and the Pressure of the saturated steam are mutually dependent. Using the Steam Property Calculator, properties are determined using Steam Pressure and the selected second parameter (Temperature, Specific Enthalpy, Specific Entropy, or Quality). Properties of the superheated steam under the sepcified temperature and pressure are listed below in both metric and standard units. For water or steam other than saturated steam, please use the general steam table. The heat energy (enthalpy of evaporation) needed at 7 bar gauge to evaporate the water to steam is actually less than the heat energy required at atmospheric pressure. Note! Steam, Boiler, and Blowdown Pressure are the same.

This general steam table uses data that covers compressed water, saturated steam, superheated steam, and supercritical water. For water or steam other than saturated steam, please use the general steam table. In other words the same pipe may transfer more energy with high pressure steam than with low pressure steam. The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow: Using the calculated feedwater mass flow and blowdown rate: Using the Steam Property Calculator, properties are determined using Steam Pressure and Quality = 0 (Saturated Liquid). Contacts | Web Site Policies Superheated Steam Region. The Specific Enthalpy is then multiplied by the Mass Flow to get the Energy Flow: Pressure = 862.6 psig Temperature = 356.3 °C Example - Boiling Water at 100 o C, 0 bar (100 kPa) Atmospheric Pressure. All Rights Reserved. C ] Released june 2007. Version: v0.9 - Build Date: 3/17/2015. Contacts | Web Site Policies Using the Steam Property Calculator, properties are determined using Steam Pressure and the selected second parameter (Temperature, Specific Enthalpy, Specific Entropy, or Quality). Boiler and fuel types are not considered. The superheated steam region depicts steam at a temperature higher than its saturation temperature. (Saturated Liquid). AddThis use cookies for handling links to social media. Semiconductors, medical equipment, lasers, optics and aviation and aerospace. Therefore, at 0 bar gauge (absolute 101.33 kN/m2) - the specific enthalpy of evaporation is 2257 kJ/kg. Steam at atmospheric pressure is of limited practical use since it can not be conveyed by its own pressure along a steam pipe to the points of consumption. Should saturated steam be heated at constant pressure, its temperature will rise, producing superheated steam. The DA has no additional heat or masses losses. | U.S. Department of Energy | USA.gov Calculate properties of combustion gases. Note: - You cannot use commas (,) as decimal points.
