Calculation of steam pressure loss
Thread Content
Hello, dear teachers. I have a steam pipeline with a DN300 diameter, 15 cm of insulation, and a length of 300 meters. The inlet temperature in the factory area is 230 degrees Celsius, the pressure is 1.4 MPa, and the flow rate is 5 tons per hour. After depressurization, the temperature is 200 degrees Celsius and the pressure is 0.8 MPa. The steam is delivered to the workshop from 2 ends. I would like to ask: after pressure reduction, what distance is there within which no condensation water is formed? Or rather, since the propulsion of steam relies on the consumption of heat, how is the amount of steam consumed during transmission calculated? Thank you
Is the power of steam generated by consuming heat? Then, the better the insulation, the less it will be possible to transport, right? When there is condensate water, it is counted as heat loss.
A temperature of 200 degrees Celsius and a pressure of 0.8 MPa correspond to superheated steam; under normal conditions, no condensation water will form.
30 kPa drop over 100m
