Regarding the issue of raising the temperature of saturated steam
Thread Content
The saturated steam used in our industry generally has a pressure of around 0.6 MPa and a temperature of 158°C. I would like to ask the experts: if I need to raise the temperature of the saturated steam to 250°C, can this be achieved using a saturated steam electric heater? And does saturated steam turn into superheated steam whenever it passes through an electric heater? If what I want is saturated steam at 250°C, what are the ways to achieve that? Thank you!
Is pressurization feasible? I don’t know much about utility systems; I just use them. I hope someone can provide a detailed explanation so I can learn more about them.
To raise the temperature of saturated steam to 250°C, a pressure of 3900 KPa is required if pressurization is used; however, such high pressure reduces the heat exchange capacity of the steam.
This can be achieved by using electric heating to heat the heat transfer oil, which in turn generates steam; both the heater and the heat transfer oil are located within the heating tube. For reference.
Pressurize it using a compressor. There is a one-to-one relationship between saturation temperature and pressure; the higher the saturation temperature, the higher the pressure as well
1. Direct heating can only produce supersaturated steam. 2.250-degree saturated steam is generally obtained through heat exchange in the boiler network. Theoretically, to convert low-pressure saturated steam into high-pressure saturated steam, it is necessary to first heat it and then increase the pressure.
It is feasible to raise the temperature by introducing low-pressure steam, but if the amount of steam is increased, a steam compressor is required; I wonder if there are any compressor manufacturers capable of producing one? If it exists, that would solve a big problem. It seems unlikely at the moment.
Is it solved? How’s it working? Which manufacturer’s product is being used? If used well, I hope you can provide the manufacturer’s information. Thank you
