Automation of excess steam condenser unit.
Automation of excess steam condenser unit.
(OP)
Greetings,
We have an excess steam condenser unit that needs to be automated in order to avoid having huge amounts of condensate and effectively utilize the steam's energy as much as we can. Unfortunately, we couldn't due to hammering issue. Please refer to the attached word doc for further explanation, and advice accordingly.
Thanks,

RE: Automation of excess steam condenser unit.
You said that the hammering starts when you get steam in the outlet condensate line. The LP steam is stated to be 60 psig so the outlet steam/condensate has to be in the area of 300F. The control range is shown as 160 to 200F, is it not starting up additional fans fast enough?
RE: Automation of excess steam condenser unit.
Burning fuel to generate steam and then discharge it to condensate through the aforementioned excess steam condensers is not practical at all, the board operator in the Central Control Room CCR is placing the PCV-1 and PCV-2 on MANUAL mode to get rid of the hammering issue. what I have observed is when we place the system on AUTO mode severe hammering will start. I am doubting about the control philosophy and as well what you have mentioned that fans will take time to start. therefore, steam/condensate will appear. I think it is a design issue and we need to resolve it ASAP to avoid this bad practice of wasting the steam energy.
your feedback is highly appreciated
thanks !
RE: Automation of excess steam condenser unit.
Have you talked to the equipment vendor? Does the equipment data sheet indicate the transient nature of the steam flow and air temperatures? The picture you attached seems to suggest a significant sized unit. Unfortunately, a lot of these units are specified at the design condition and the wide range of operating conditions it has to operate at are not included for the equipment vendor to consider.
