Heating coil steam pressure
Thread Content
Is it better to use 1.0 MPa superheated steam or 0.45 MPa superheated steam for heating storage tanks? There is a saying that systems with high pressure have low entropy and poor functional capacity, so one should choose those with low pressure. What do you all think?
Theoretically, both are possible; the key lies in two points: 1. Temperature requirements and safety. The decision is made based on the temperature to which the material in the tank needs to be heated. However, high-pressure steam poses a risk of raising the temperature of the storage tank too much. 2. Current configuration of the steam pipeline network: The tank farm is a steam user, and it is generally not possible to have an independent pipeline network. So generally, one looks at the pipeline network configuration in the factory area.
These days, safety is the top priority in design. We can always increase the heating area if necessary. We use multi-layer coils with a pressure reduced to 0.1 Mpa, haha. . .
