We have 2 x 100% configuration hrsg feed water pumps. And i have seen some of the reference P & ID's where the minimum recirculation lines are separate for each pump and each line is connected separately to the source.
Can't we combine the two minimum recirculation lines to a common header and then use a singl line to the source.
We are using Autorecirculation Valve at the Pump discharge. Hence in my opinion, even if individual minimum recirculation lines are combined together no problem will occur since Autorecirculation valve has a check valve.
Please comment if there are any technical problems with this.
