Calorific value of 1 ton of steam
Thread Content
What is the heat output of 1 ton of steam when the pressure in the steam boiler is 7 KG/CM²? Thank you!
The enthalpy of 0.7MPa saturated steam is 2763.3 kJ/kg. (Refer to the tables of thermodynamic properties of water and water vapor.) At 0.7 MPa, the heat release per ton of steam is: 1000 Kg × 2763.3 KJ/Kg = 2763.3 MJ. This post was last edited by sejny on 2009-4-18 at 11:25
Your question is too general. Under this pressure, 1 kg of steam turning into saturated water at the same temperature can release 490 calories of heat. Generally, it is assumed that boilers with a capacity of 0.7 MW or 600,000 calories are considered 1-ton boilers; in other words, the amount of heat required to produce 1 ton of steam is 0.7 MW, or 600,000 calories.
