Steam generator furnace pressure
Steam generator furnace pressure
(OP)
Hello to everyone, i work at a thermal power plant that a firing optimisation and rehabilitation project is going on now. We have started to commisioning at unit 1. But we have a problem. Problem is following, before the rehabilitation furnace presseure was fluctuating between -2 and 0 mbar but now it is fluctuating between -8 and 0 mbar. Do you think what must be the fluctutating range ? And how can i find a standard or other document about this subject.

Also, partial plugging of regenerative air heaters could be introducing instabilities that could be disturbing the responses of the fan control systems. If the frequency of pressure fluctuations is similar to the rotating frequency of the air heaters, then I would want to pay this possibility more serious attention.

If the fans are eliminated as suspects, the next things to look at are burner control and fuel feeding.
