Advantage Of L Pr Boiler And H Pr Boiler

< The hydraulic separator was involved to separate the PHE loop and the boiler loop on the heating water side. This solution brings the advantage of the independence of the heat transfer in the boiler itself, because the hydraulic condition in the boiler is nearly constant and it is independent on the flow condition in the PHE for varying mass flow.
