Help! Seeking help from experts! On the energy-saving principle of 3.5 MPa steam
Thread Content
The heating source for my work equipment is 3.5 Mpa steam, which is reduced in pressure and temperature to become 1.1 Mpa steam for use (as required by the process). Previously, the steam pressure at the front end was controlled at around 2.5 Mpa, which resulted in higher energy consumption. Now, by increasing the pressure at the front end and then reducing both the temperature and pressure, the pressure and temperature remain unchanged, while the steam-related energy consumption is reduced. I know this is because the density of the steam increases, thereby raising its calorific value. But are there any other principles behind this phenomenon, as per the experts here? I need to create a presentation in the future, and I really need the help of experts! If possible, we could also become friends so as to discuss industry issues regularly! Thank you all, experts!

In this way, the specific heat, that is, the enthalpy per mass, does not decrease? I guessed; I don’t understand this
The description of the problem is highly unprofessional, filled with made-up terms that are meaningless.
The heat source of your heater has been increased from 2.5 MPa to 3.5 MPa; considering the heat contained in the steam, and with the outlet control parameters remaining unchanged, it’s clear that the heat transfer capacity at 3.5 MPa is much higher. Moreover, the design also requires 3.5 MPa, so energy consumption will definitely decrease under these conditions.
It’s actually very simple: to obtain a certain amount of saturated steam at 1.1 MPa, if steam at 3.5 MPa is used, less steam will be required. The premise is that the temperature and pressure reduction process is an isenthalpic process.
However, his concept of energy conservation is incorrect; it is not appropriate to use steam at 3.5 MPa, which is equivalent to cutting large diamonds into smaller diamond particles.
