Questions about steam heating temperature
Thread Content
The steam provided by the company's power workshop is in the range of 0.5Mpa to 0.7Mpa. The 1000L reactor is heated with steam. The steam passes through the safety valve from the upper part of the jacket (the setting value is 0.1Mpa pressure starting), enters the jacket for heating, and is drained from the bottom of the jacket through the trap. However, the temperature of the reactor cannot rise by 100 degrees. Is it because the steam pressure is not enough or the insulation effect of the reactor is not good?

Is this the case with you?: 1: The jacket is heated with 0.5~0.7MPa steam 2: But why does the jacket have a safety valve with a trip pressure of 0.1MPa? Isn’t all the steam taking off and finished?
I agree with what was said above. The poster did not describe it clearly. What is the safety valve? It is impossible for the steam pressure to fluctuate by 2 kilograms during production, right? Please explain clearly.
If possible, increase the pressure of the safety valve. At this time, the steam temperature is not important, the key is the pressure. The heating temperature corresponds to the saturation temperature under the steam working pressure. Increasing the pressure increases the heating temperature. The 0.1MPa steam saturation temperature is about 110 degrees (did not check the table).
What everyone above said is wrong. I understand that the safety valve is for the reactor. Steam is used for heating. Heating to 100°C depends on the boiling point of the reaction medium at 2 kg of pressure. If the boiling point is less than or equal to the boiling point, it must be adjusted. At this time, if the temperature needs to be increased, the pressure needs to be increased. right
