Coal-to-hydrogen purification and conversion unit
Thread Content
I would like to ask everyone: before stopping the unit, if the injection system of the waste boiler is shut down one day in advance, will the steam generated by that waste boiler still be fed into the pipeline network? Is there any problem with this? Could shutting down the system in advance result in the steam not meeting the required standards?
Chemical dosing in waste boilers is primarily aimed at reducing scaling, and it does not affect the quality of the steam.
No, chemicals are added to prevent scaling, and you surely conduct regular analyses as well; not adding these chemicals for a short period of time has no impact on the system
It is now equipped with an isothermal reactor for high-concentration CO conversion; the reactor itself functions as a steam boiler, connected to a steam-water circulation drum that produces saturated steam at 3.9 MPa. The technology of Hunan Anchun Company is really excellent. Why add chemicals? This requirement applies to deoxygenated demineralized water. Is it necessary to add chemicals for normal sewage discharge?
