Saturated steam jet pressure reduction
Thread Content
The boiler produces saturated steam at 4.9 MPa in a volume of 1 ton. Due to process requirements, this steam is depressurized by spraying water to produce saturated steam at 1.0 MPa, which is then used for heat exchange. How many tons of saturated steam at 1.0 MPa can be generated? How is this calculated? Thank you!
The welding value for 5.0 MPa steam (absolute pressure) is 668.47 kal/kg, while that for 1.1 MPa steam is 665 kal/kg; the ratio of the two is 1.0052.
The welding value for steam at 5.0 MPa (absolute pressure) is 1154.5 kJ/kg, while that for steam at 1.1 MPa is 781.2 kJ/kg; the ratio of these two values is 1.478 tons
The 2nd and 3rd floors provide two sets of steam enthalpy data respectively; which one is closer and more suitable for use as the data to be collected? Please ask experts for further guidance!
Doing this is unreasonable; it’s not cost-effective at all. A pressure relief valve should be installed first, and only then should water be sprayed to achieve saturation.
