Steam mixing at different temperatures
Thread Content
Our company produces some 4.0 MPa saturated steam (260°C), and it is somewhat difficult to use this steam directly for power generation. We plan to reduce the pressure of the steam produced by boilers and mix it with this steam (at a reduced pressure of 4.0 MPa, around 500°C), before using it for power generation. 1. There is a significant temperature difference between the two types of steam; is there any risk in mixing them directly? Are there any things to be careful about? 2. Are there any practical examples of using saturated steam at 4.0 MPa directly for power generation? 3. Have you learned about the inter-stage drainage in saturated steam turbines? I have a question.
They cannot be mixed. The temperature difference between the two streams of steam entering the turbine in parallel must not exceed 17 degrees.
Could we add something like a buffer tank ahead of it before it goes into the steam turbine?
