What are the approximate temperatures and pressures of medium-pressure steam condensate and low-pressure steam condensate? Can they be collected in the same pipe?
Sure, as long as the pressure of the condensate water is the same!
From the perspective of steam conservation and process control, it is not recommended. 1. The condensate pressure corresponds to the pressure of the medium-pressure and low-pressure steam ； The temperature is the saturation temperature of medium-pressure steam and low-pressure steam at that pressure. 2. Collection in the same tube: If the pressure at the collection point is higher than the pressure of the low-pressure steam, the low-pressure condensate cannot enter, which is also uneconomical. Suggestion: Medium-pressure steam should first enter the flash tank; the flash pressure should be the same as that of low-pressure steam. The low-pressure steam resulting from flashing is incorporated into the low-pressure steam pipeline network, while the condensate produced by flashing merges with the low-pressure condensate.
1. Both medium-pressure and low-pressure are ranges; it is necessary to determine the pressure first before checking the saturated vapor pressure. 2. Steam generally makes use of its latent heat, so the temperature and pressure of the condensed liquid do not decrease. 3. Medium-pressure condensed liquid can be converted into low-pressure steam and low-pressure condensed liquid through flashing, which allows the heat from the high-pressure condensed liquid to be recovered, after which the low-pressure condensed liquids can be mixed together
