How can saturated steam at 6 kg be used to produce superheated steam at around 130 degrees in a DN65 pipeline? Urgent! Urgent! Urgent! ! !

The saturation steam temperature at 0.6 MPa (G) is above 160 degrees, while superheated steam is not 130 degrees

As long as it’s over 130, that’s fine

To produce superheated steam at around 130 degrees, the following steps can be followed: 1. Ensure that the pressure of the saturated steam is 6 kg, and introduce this saturated steam through a DN65 pipe. 2. The received saturated steam needs to be pressurized before it enters the system. Appropriate steam pressurization equipment (such as steam pressure pumps) can be used to raise the pressure to that required for generating superheated steam. 3. The pressurized steam is sent to the superheater, where it is heated by heating elements such as electric heating tubes or heat exchangers, raising its temperature to that required for producing superheated steam (around 130 degrees). 4. Ensure that the control system of the superheater can accurately regulate the steam temperature, so as to maintain a stable temperature during the production process. 5. Ensure that pipelines, superheaters, and related equipment possess sufficient safety and pressure resistance capabilities to prevent equipment damage or safety incidents caused by excessive pressure. Please note that the above are only the steps for generating superheated steam under normal circumstances; the actual operations need to be adjusted and carried out according to the specific conditions and characteristics of the equipment. For operations and equipment involving steam, it is necessary to ensure guidance and supervision by qualified professionals, as well as strict adherence to the relevant safety procedures. .

The temperature of the saturated steam at 0.6 Mpa after it is received is 165°C, which is above 130°C! Steam at 0.6 Mpa is considered superheated steam only if its temperature is above 165°C. Without pressure relief, when the steam temperature drops to 130°C, the pipeline will be filled with water (this can cause severe liquid slugging in the pipeline during use, leading to danger)! Additionally: The steam pressure corresponding to saturated steam at 130℃ is 0.17 Mpa. Emphasize that for superheated steam, the pressure must be < 0.17 Mpa. In other words: if steam at 130°C is required, a temperature-reducing pressure regulator is needed.

Secondary heat exchange can be arranged in the boiler, or a separate superheater can be used to raise the steam temperature by utilizing hot flue gas or separate heating. Alternatively, by allowing steam to expand to a low pressure after passing through the nozzle of a pressure reducing valve, the superheat can be increased by utilizing the energy changes during the throttling process.
