Dear experts, my factory has low-pressure steam at 225°C and 1.0 MPag. Due to the requirements of the subsequent equipment design, it is necessary to raise its temperature to 240°C while keeping the pressure at 1.0 MPag. What are the possible methods to achieve this? Which method is the most cost-effective and practical? Please give me some advice.
Constant pressure, rising temperature? Isn’t this the conversion of saturated steam to superheated steam, through heating?
A superheating heat exchange device that requires steam needs to be added. The saturation temperature at 1.0 MPa is 184°C; when the temperature rises to 240°C, the superheat is 56°C. The sensible heat temperature change requires additional heat to be supplied.
You can look up heat pump technology.
What is the purpose of increasing the steam pressure? If it is used as a heat source to heat a medium to 240°C, and saturated steam at this pressure is converted into superheated steam at a higher temperature through wall-to-wall heat transfer, then using this superheated steam for heating will result in a reduced heating effect. Superheated steam is utilized for its kinetic energy; it is produced and applied precisely because its thermal energy is difficult to release. The method on the 4th floor is feasible; by using heat pump technology to increase the pressure, the temperature of the saturated steam at a higher pressure is raised as well
First, it is possible to raise the temperature of the entire steam network to meet the requirements of subsequent equipment. Second, a steam compressor is used to increase the temperature and pressure, which are then reduced before use~~
Electric heating, far-infrared; it’s feasible for small quantities, while for larger amounts, the methods mentioned above can be used
Such a high question? Wouldn’t it be better to use heat transfer oil directly?
