How to put a temperature and pressure reducer into use
Thread Content
How should medium-pressure steam at 3.5 Mpa and 420°C, and deoxygenated water at 6.4 Mpa and 104°C be fed into the temperature reduction pressure regulator? What is the correct sequence? What specific temperature is it?
Reduce pressure first and then add water: Steam → Pressure control valve → Desuperheater → Downstream. ↑ Add water; the specific temperature depends on the temperature you desire (basically, it should remain in a vapor state at that temperature)
