It is difficult to adjust pressure and temperature after the temperature reduction regulator

Two are not enough; the steam supply pipeline before pressure reduction is not thick enough, and the water supply capacity of the deaerated water system is insufficient.

Can the stripped waste steam be compared to steam at 1.0 MPa? First of all, the pressure is lower than 1.0 MPa; you are using deoxygenated water, so the pressure has to be kept low.

It must be related to the waste steam from the integrated stripping condensate tank； You might consider setting the steam manual valve before the temperature reduction regulator to the flow rate it had when operation started, and then see if the pressure and temperature can be adjusted more easily.

At the moment, we are unable to increase the temperature in the regeneration tower; the gas return stream from the reboiler is fluctuating severely. Is this related to the temperature and pressure after the temperature reducer and pressure regulator?

How can one determine whether the injection of cooling water is unobstructed? If the amount of cooling water injected is indeed low, how can it be increased without affecting the operation of the equipment?

I think all the problems are related to the integration of the waste steam from your stripping condensate tank into the temperature reduction pressure reducer. You can limit the amount of waste steam from the stripping condensate tank that is fed into the temperature reduction and pressure reduction unit, or simply stop it altogether, and see how things go.

Is the amount of waste steam from the stripping condensate tank fixed? This portion of the waste steam is saturated steam; therefore, it is recommended that the point at which the waste steam is combined with the main stream be located after the remote temperature sensor. In this way, the temperature and pressure reduction device can function properly. Since the waste steam after reduction is still saturated steam, it does not affect the steam supply to the system

Based on the original question posed by the poster, the amount of superheated steam produced after startup increased by 5–8 tons per hour; the supply of condensate water was at full capacity. Yet, the temperature after temperature and pressure reduction was still high, which is due to the fact that the steam remained in a superheated state, indicating an obvious insufficient amount of desalinated water. Another issue is the steam at saturation state that flows into the main pipeline after pressure reduction; has the pressure of this steam been determined? If the pressures of the two are different, it will cause the pressure relief valve to fail. What was originally saturated steam may also turn into superheated steam if it is further heated by the incoming superheated steam. The inlet can be placed at the steam inlet, a distance away from the rear end of the remote temperature sensor; this way, it will affect the use of that portion of the waste steam without impacting the data from the remote temperature sensor. The temperature in the regeneration tower cannot be increased, and there is severe fluctuation in the vapor return line from the reboiler, which indicates that water has entered the steam pipeline – and a considerable amount of it. This could be due to poor atomization of the deionized water (less likely) or water being carried along with the waste vapor (more likely). A drain line and valve can be installed on the steam supply pipeline (drain valves are not recommended; gate valves or stop valves can be used) to allow for rapid drainage.

The high temperature you’re experiencing is likely due to insufficient water volume. As for the low pressure, check the installation location of the pressure transmitter – it should be placed a little further away from the pressure reduction device to obtain more accurate readings
